Modern economy and high-speed development, peopleundefineds industrial equipment is also continuously developing, in which the use of the breaking hammer is also very frequent, in which, for the crushing hammer factory, it is also very challenging, but the use of the crushing hammer and the excavator is still not well understood, In the following, Yantai Puxi Hydraulic Equipment Co., Ltd. provides you with the following: 1. Use a high-quality breaking hammer. The inferior crushing hammer is easy to solve due to the design, manufacture and inspection, and the failure rate is high, and the excavator is more likely to be damaged; 2. Suitable engine speed. As the crushing hammer has lower working pressure and flow requirements (such as 20-ton excavator, the working pressure is 160 to 180KG, the flow rate is 140 to 180 L/ MIN), the middle throttle can be operated; if the large-throttle operation not only does not increase the impact force, the hydraulic oil is abnormally heated, and the hydraulic system can also be damaged; 3. Correct butter position, frequency and quantity. The grease shall be supplemented in the straight state of the steel, and the grease shall be filled every two hours. If the lubricating grease is supplemented in the suspended state of the steel, the grease enters the striking chamber, and the abnormal high-pressure oil can be generated in the striking chamber to enter the hydraulic system, and the hydraulic pump is damaged; 4. Hydraulic oil quantity and pollution. Since the hydraulic oil pollution is one of the main reasons leading to the failure of the hydraulic pump, the pollution condition of the hydraulic oil shall be confirmed in time (the hydraulic oil is changed for 600 hours and the filter element is replaced for 100 hours). The lack of hydraulic oil will cause cavitation, such as hydraulic pump failure, broken hammer piston cylinder strain, etc.; it is suggested that the oil level should be checked before being used every day; 5. Replace the oil seal in time. The oil seal belongs to the wearing parts. It is recommended that the breaking hammer work for 600-800 hours and replace the one-time crushing hammer oil seal. When the oil seal is leaking, the oil seal must be stopped immediately, the oil seal is replaced, and the dust on the negative side is easy to enter the hydraulic system, and the hydraulic system is damaged and the hydraulic pump is damaged. 6. Keep the pipeline clean. The crushing hammer pipeline must be thoroughly cleaned and the return oil circuit is in cycle butt-jointed; when the bucket is replaced, the broken hammer pipeline must be blocked and the pipeline is kept clean. The hydraulic pump can be easily damaged after the sundries such as sand enter the hydraulic system. The above is how to use the crushing hammer to do not damage the excavator, and I hope that the introduction can help you.

Many masters will doubt such a question, why the broken hammer bought at the same time is used by others for a longer time than themselves, in fact, such a result is not unexpected, the following Yunnan engineer broken hammer Xiao Li will share with you the maintenance, installation of broken hammer skills and details. First: venue is key Choose a clean, clean, flat site, be sure to stay away from dust, debris, put the hammer on two pieces of wood. Remember to clean the dirty hoses and connectors in time. It is recommended to use special cleaning oil for better effect. Second: installation steps (1) After the host and the site are ready, the first step is to align the boom of the host with the center of the crushing hammer pin. Next, carefully lower the host connecting rod, align the pin hole on the boom with the pin hole on the crushing hammer support, and then insert the pin shaft. (2) Install the stop ring, align the bolt hole and insert the bolt. Cross tighten the two nuts. Note that if the stop ring is too tight with the nut, it will shorten the life of the bolt or cause it to become loose. (3) Shut off the engine, if there is pressure in the hydraulic tank must be released completely. Turn the closure valve mounted on the end of the main boom 90 degrees to prevent hydraulic oil from flowing out. Nitrogen pressure will cause the rod to fly out. Do not operate near the rod. (4) Loosen the tube plug on the crushing hammer hose and the tube joint cover on the front end of the main boom, and then connect the high pressure and low pressure oil hose to these joints respectively. There will be a small amount of hydraulic fluid, so find a container. Third, disassembly steps (1) The disassembly steps of the crushing hammer are opposite to the installation. After disassembly, plug the hose on the crushing hammer with a pipe plug to prevent mud and dust from entering the hose. Also cover the joint on the main boom to prevent dust from entering the piping. Be careful to take care of the removed parts. (2) If the broken hammer removed is not used for a long time, anti-rust and other work must be done, such as grease coated on the clamping part of the drill rod, unloaded the hollow plug, spray a layer of anti-rust oil on the front of the piston, and the crushing hammer should be kept indoors.

Crushing hammer may be in addition to the bucket, excavator is the most commonly used tools, and with the hammer, excavator work to make more money, but we also know that "shooting" is very harmful to excavator itself, especially incorrect operation. Precautions for operation are as follows (1) When using the crushing hammer each time, first check whether the high pressure or low pressure oil pipe of the crushing hammer is loose; At the same time, for the sake of caution, we should always check whether there is oil leakage in other places, so as to avoid a oil pipe falling off due to vibration and thus failure. (2) In the crushing hammer operation, the drill rod should always be vertical to the surface of the broken object. And make the rod is pressed to be broken object, broken should immediately stop crushing hammer work, in order to prevent air play. Continuous aimless impact will cause damage to the precursor of the crushing hammer and loosening of the main bolt, and can hurt the host itself in serious cases. (3) when crushing, do not use shaking rod, otherwise the main bolt and rod may be broken; Do not make the crushing hammer fall down quickly or hit hard stones, which will damage the crushing hammer or main engine due to excessive impact. (4) Do not crush in water or mud. In addition to the rod, other parts of the crushing hammer body should not be immersed in water or mud, otherwise the piston and other parts with similar functions will cause premature loss of the crushing hammer due to the accumulation of mud. (5) when breaking especially hard objects, should start from the edge, do not continuously beat more than 1min at the same point, in order to prevent rod burning or hydraulic oil overheating. (6) Do not use the protection plate of the crushing hammer as a tool to push heavy objects. Because the mining loaders are mainly minicomputers, their weight is light. If they push heavy objects, the crushing hammer will be damaged if they are light, and the lifting arm of the main engine will be broken if they are heavy, and even the main engine will overturn. 323/5000 (7) The operation is carried out when the hydraulic cylinder is fully extended or fully contracted, otherwise the impact vibration will be transmitted to the hydraulic cylinder and thus to the host. Maintenance of crushing hammer Because the working conditions of the crushing hammer are very bad, the correct maintenance can reduce the failure of the machine and prolong the service life of the machine. In addition to the timely maintenance of the host, the following points should also be paid attention to: 1, appearance inspection: check whether the bolts are loose; Whether the connecting pin shaft is excessively worn; Check whether the clearance between the drill rod and its bushing is normal, and whether there is oil leakage in the interval, indicating that the low-pressure oil seal has been damaged, and professionals should be asked to replace it. 2. Lubrication: The lubrication point of the working device should be lubricated before operation and after each continuous operation for 2 ~ 3h. 3, replace the hydraulic oil: the change of the hydraulic oil quality is different because of the different working environment. The simple way to judge the quality of the oil is to observe the color of the oil. When the oil quality turns bad is very serious, the oil should be let off, and then inject new oil after cleaning the tank and oil filter.

As we all know, in daily life, many safety accidents are caused by mechanical equipment, and most of the reasons are caused by improper maintenance of mechanical equipment. Indeed, strengthening the maintenance of large crushing hammer manufacturers' products is a necessary means to ensure the normal and safe operation of equipment. It can not only prolong the service life of mechanical equipment, but also ensure the safe, reliable and efficient operation of mechanical equipment to avoid safety accidents, personal injury and property losses. At present, large crushing hammer is widely used in road and railway construction, engineering construction, mining and other fields, but the workplace of the products of large crushing hammer manufacturers is very extreme, and there may be problems in the process of use. Let's take a look at the cause of the abnormal noise produced by the large crushing hammer. 1. The automatic exhaust valve is damaged, the valve spring is yellow and soft or damaged, and the load regulator is not adjusted correctly. All of these can cause an abnormal sound in the valve chamber. 2. If some parts of the crushing hammer splint have problems, abnormal sounds may be emitted. According to the large crushing hammer manufacturer, the actual operator can distinguish the abnormal sound. 3, crankcase crank pin bolts, nuts, crankshaft bolts, crosshead bolts loose, off, broken, seriously damaged diameter, increased clearance, crosshead pin and sleeve is too large or damaged. There's an abnormal sound in the crankcase. 4. The gap between the piston and the cylinder head is too small to produce a direct impact sound. 5. The connecting nut of the piston rod and piston of large crushing hammer manufacturers loosens or disconnects, the inner hole of the piston is blocked, the piston sticks and hits the cylinder cover, the metal debris falls into the cylinder, and the moisture accumulates and produces abnormal sound. With the crushing hammer, the cylinder rod cannot be fully extended or retracted to work, as this causes more damage to the cylinder block and the car itself. The other thing is to make sure that the body is placed as firmly as possible in the broken parts and that the drill pipe is compressed to do the work. In addition, large crushing hammer can not be put into the water to work, large crushing hammer manufacturers said that it will cause serious damage to the hydraulic seal in the hammer body.

Modern economy and high-speed development, peopleundefineds industrial equipment is also continuously developing, in which the use of the breaking hammer is also very frequent, in which, for the crushing hammer factory, it is also very challenging, but the use of the crushing hammer and the excavator is still not well understood, In the following, Yantai Puxi Hydraulic Equipment Co., Ltd. provides you with the following: 1.

As one of the most common accessories in construction machinery, excavator hydraulic crushing hammer has been widely used in mines, railways, highways, municipal work occasions. In the face of bad construction site, not only to ensure the construction efficiency, but also to ensure the construction safety. Next, expand into small series from several aspects to summarize the safety use of the crushing hammer: 1. Install carefully The installation of crushing hammer is the premise of construction. Only by improving the quality of construction machinery installation can we reduce the safety accidents. In this regard, the installation process and standard of the crushing hammer shall be determined according to the relevant construction machinery and equipment installation work specifications, so as to ensure that the installers and later users can accurately install and use the crushing hammer according to the standards. For example, the installation personnel shall strictly check the qualification specification and qualification certificate of the crushing hammer, and at the same time carefully check the auxiliary components needed for the crushing hammer installation to ensure the smooth installation. 2. Trial operation is necessary The actual operation is to check the mechanical performance and specification of parts installation before the crushing hammer is put into use. The proper debugging is also to further test the quality of the crushing hammer and reduce the failure of the crushing hammer as much as possible. After the trial machine is completed, reinforce each part again. 3. Standardize operation to reduce damage Personnel's protective equipment configuration and operation method selection. For example, before the strike, select the appropriate strike point and confirm that the brazing rod is indeed stable before the operation strike. Do not use as a sledge hammer. Place the bit on the ground before starting. Never use the crusher as a sledge hammer to break objects. The above is yantai pukun hydraulic equipment co., LTD. On the safe use of the three points of the crushing hammer, these three points are directly related to the safety of the operation and the service life of the equipment, each can not be careless.

Explain the correct use of hydraulic crushing hammer. 1) Carefully read the operation manual of hydraulic crushing hammers to prevent damage to hydraulic crushing hammers and excavators and operate them effectively. 2) Before operation, check whether the bolts and connectors are loose, and whether there is leakage in the hydraulic pipeline. 3) Do not use a hydraulic hammer to peck holes in hard rock. 4) It is not allowed to operate the crushing hammer when the piston rod of the hydraulic cylinder is fully extended or fully contracted. 5) When the hydraulic hose vibrates violently, the operation of crushing hammer should be stopped and the pressure of accumulator should be checked. 6) To prevent interference between the arm of the excavator and the bit of the crushing hammer. 7) Do not immerse the crushing hammer in water except the drill bit. 8) Crushing hammer shall not be used as lifting device. 9) Crushing hammer shall not be operated on the crawler side of excavator. 10) When the hydraulic crushing hammer is connected with the hydraulic excavator or other engineering construction machinery, the working pressure and flow of the hydraulic system of the host must meet the technical parameter requirements of the hydraulic crushing hammer. The "P" port of the hydraulic crushing hammer is connected with the high pressure oil circuit of the host, and the "A" port is connected with the oil return circuit of the host. 11) The best hydraulic oil temperature of hydraulic crushing hammer is 50-60 degrees, and the highest temperature shall not exceed 80 degrees. Otherwise, the load of hydraulic crushing hammer should be reduced. 12) The working medium used by hydraulic crushing hammer can usually be consistent with the oil used in the hydraulic system of the host machine. It is recommended to use YB-N46 or YB-N68 anti-wear hydraulic oil in general areas, and yC-N46 or YC-N68 low-temperature hydraulic oil in cold areas. Hydraulic oil filtration accuracy is not less than 50micro; M. 13) New and repaired hydraulic crushing hammers must be re-filled with nitrogen at a pressure of 2.5, ±0.5MPa. 14) between the rod handle and the cylinder guide sleeve must be lubricated with calcium base grease or compound calcium base grease, and each shift is injected once. 15) When working, the hydraulic crushing hammer must first press the rod on the rock, and maintain a certain pressure before starting the crushing hammer, which is not allowed to start in the suspended state. 16) It is not allowed to use the hydraulic hammer as a crowbar to avoid breaking the drill bar. 17) Hydraulic crushing hammer and fiber rod should be perpendicular to the working face when used, in order to not produce radial force as the principle. 18) When the broken object has cracked or started to crack, the impact of the crushing hammer should be stopped immediately to avoid harmful "empty beating". 19) If the hydraulic crushing hammer wants to stop using for a long time, nitrogen should be discharged, and the oil inlet and outlet should be sealed, and the cutting iron should be stored in high temperature and -20 degrees below the environment.

Gun head, also known as crushing hammer, stone crushing, crushing device, is one of the accessories often used by excavators, often used for mountain cutting, breaking road surface, house demolition, bridge demolition, mining crushing stones and other working conditions. The structure of the gun head is mainly divided into three blocks: the upper cylinder body (nitrogen chamber), the middle cylinder body (oil cylinder), the lower cylinder body, the three are connected by four full-body bolts. The upper cylinder is used to store low-pressure nitrogen, the middle cylinder is the piston, accumulator, oil seal, air exchange valve and so on, the lower cylinder has steel, flat pin, horizontal pin, inner and outer bushing. It can be seen from the above figure that the main structure of crushing hammer is divided into hammer body (movement) and bracket, in which the upper splint and the lower splint respectively protect the movement, and the drill rod is in direct contact with the material in crushing operation. The accumulator mainly plays a buffer protection role, which can prolong the service life of the crusher to a certain extent. Generally small crushing hammer or crusher hammer with diameter less than 10cm is not equipped with accumulator. Gun head is powered hydrostatic pressure, hydraulic drive piston run up, compressed nitrogen at the same time, when the piston to the reversing valve, hydraulic direction change makes the piston down, at the same time, influenced by nitrogen and piston weight force, so that the piston high-speed impact drill rod, the reciprocating motion of broken rock, concrete and other solid operations.

Hammer crusher as one of the most widely used crushing equipment, vulnerable parts hammer choose what material is best? This is a question that is often discussed and one that deserves attention. Wear resistance in the process of use is the focus of many customers, but also the key to inject research power of producers. On the market, crusher hammer is common with high manganese steel hammer, high chromium hammer, manganese alloy hammer, chromium alloy hammer, hard alloy hammer, chromium manganese composite hammer, carbon steel hammer etc., if you want to ask which kind of crusher hammer is the best to use? It must be decided according to its working conditions, different working environments and different effects of use. Such as broken stone stone, pebbles and other very hard ore, this time with high manganese steel or high manganese steel alloy effect is the best, because the characteristics of high manganese steel is the greater the impact force, the more wear-resistant; But if the broken coal, limestone, these are not very hard materials, it is difficult to play its wear resistance with high manganese steel, this time with high chromium alloy hammer, the effect is good. So what material crusher hammer is the best to use? It depends on what scenario is being used, right

Many masters will doubt such a question, why the broken hammer bought at the same time is used by others for a longer time than themselves, in fact, such a result is not unexpected, the following Yunnan engineer broken hammer Xiao Li will share with you the maintenance, installation of broken hammer skills and details.

Next, carefully lower the host connecting rod, align the pin hole on the boom with the pin hole on the crushing hammer support, and then insert the pin shaft. (2) Install the stop ring, align the bolt hole and insert the bolt. Cross tighten the two nuts. Note that if the stop ring is too tight with the nut, it will shorten the life of the bolt or cause it to become loose. (3) Shut off the engine, if there is pressure in the hydraulic tank must be released completely. Turn the closure valve mounted on the end of the main boom 90 degrees to prevent hydraulic oil from flowing out. Nitrogen pressure will cause the rod to fly out. Do not operate near the rod. (4) Loosen the tube plug on the crushing hammer hose and the tube joint cover on the front end of the main boom, and then connect the high pressure and low pressure oil hose to these joints respectively. There will be a small amount of hydraulic fluid, so find a container. Third, disassembly steps (1) The disassembly steps of the crushing hammer are opposite to the installation. After disassembly, plug the hose on the crushing hammer with a pipe plug to prevent mud and dust from entering the hose. Also cover the joint on the main boom to prevent dust from entering the piping. Be careful to take care of the removed parts. (2) If the broken hammer removed is not used for a long time, anti-rust and other work must be done, such as grease coated on the clamping part of the drill rod, unloaded the hollow plug, spray a layer of anti-rust oil on the front of the piston, and the crushing hammer should be kept indoors.

Hammer crusher hammer on the market can be divided into two kinds according to the manufacturing process: casting and forging, but their wear resistance is not the same. Due to the crushing material, the head needs good wear resistance and the handle needs enough toughness, usually alloy steel, high manganese steel, cast steel and high chromium cast iron bimetal composite materials by forging or casting method a molding, with the corresponding heat treatment process is more economical, crusher hammer according to the material can be divided into: High manganese steel hammer head, bimetal hammer head, composite hammer head, big gold tooth hammer head, medium chromium alloy hammer head, hard alloy hammer head. The main factor is the content of silica. Modern industrial technology shows that the use of cemented carbide hammer has a good performance on wear resistance.

Crushing hammer may be in addition to the bucket, excavator is the most commonly used tools, and with the hammer, excavator work to make more money, but we also know that "shooting" is very harmful to excavator itself, especially incorrect operation. Precautions for operation are as follows (1) When using the crushing hammer each time, first check whether the high pressure or low pressure oil pipe of the crushing hammer is loose; At the same time, for the sake of caution, we should always check whether there is oil leakage in other places, so as to avoid a oil pipe falling off due to vibration and thus failure.

(4) Do not crush in water or mud. In addition to the rod, other parts of the crushing hammer body should not be immersed in water or mud, otherwise the piston and other parts with similar functions will cause premature loss of the crushing hammer due to the accumulation of mud. (5) when breaking especially hard objects, should start from the edge, do not continuously beat more than 1min at the same point, in order to prevent rod burning or hydraulic oil overheating.

The power source of hydraulic crushing hammer is the pressure provided by excavator, loader or pumping station, which can break stone and rock more effectively and improve working efficiency in engineering construction. The principle of selecting hydraulic crushing hammer is to select suitable hydraulic crushing hammer according to excavator model and working environment. The characteristics of hydraulic crushing hammer are introduced below. 1.Hydraulic crushing hammer can ensure high quality, piston, Main Body front, cylinder, main body rear and other main parts produced by new heat treatment equipment, in addition, many years of technical experience to ensure the stability of excellent quality. 2.Using high quality material special technology to manufacture piston, theme bolt, main body front, cylinder, main body rear and other important parts of the material is through the strict quality inspection of the company. 3.The impact energy enhanced structure design hydraulic crushing hammer adopts the optimization design idea, increases the piston and cylinder block stroke, adopts the piston and the brazing rod equally large diameter, causes the crushing hammer to match the main engine very well, reasonably uses the high output energy, saves the energy, achieves the work efficiency extremely high. Hydraulic crushing hammer has become an important working tool of hydraulic excavator. Hydraulic crushing hammer is installed on excavator loader or wheel loader for crushing operation.

The long and short bolt of crushing hammer plays the role of fastening the connection, and the stress is more complicated, so it is easy to be damaged. In the daily maintenance work of the crushing hammer, apart from the replacement of some large vulnerable parts, it is also necessary to check and replace the length and length of the crushing hammer bolts, check whether the bolts and nuts are loose, damaged and fall off the whole body bolts, splint bolts, accumulator bolts are damaged. Then how to replace the long and short bolts? The following is to listen to our yantai crushing hammer manufacturers for you to summarize the practical experience: 1.Before unscrewing the through-body bolt, the nitrogen in the upper body should be completely released. In case of nitrogen resistance, unscrewing the bolt strictly so as to avoid internal damage to personnel. 2. After removing the overall bolt, the staff of yantai crushing hammer manufacturer will generally check whether the bolts of the crushing hammer have cracks, wear and other damages. If there is any damage, replace them in time. 3. When installing the length bolts of the whole body crushing hammer, please pay attention not to tighten one bolt at one time, and the next bolt should be tightened synchronously, so as to avoid the tightness of one bolt and the damage of others without tightening. 4. The selection of tools is also crucial for the loading and unloading of spare parts. On the one hand, appropriate tools can help the smooth loading and unloading; On the other hand, select the torque wrench in accordance with the specifications, the correct application of force can avoid the screw during the installation process. When we install the bolt length of the crushing hammer, we must operate in strict accordance with the above method. Due to the negligence of installation, the failure of using the crushing hammer in the later stage occurs. After reading the above introduction, please feel free to contact our yantai crushing hammer manufacturer if you need any service to replace the bolts of the crushing hammer.

Crushing hammer may be in addition to the bucket, excavator is the most commonly used tools, and with the hammer, excavator work to make more money, but we also know that "shooting" is very harmful to excavator itself, especially incorrect operation. Precautions for operation are as follows (1) When using the crushing hammer each time, first check whether the high pressure or low pressure oil pipe of the crushing hammer is loose; At the same time, for the sake of caution, we should always check whether there is oil leakage in other places, so as to avoid a oil pipe falling off due to vibration and thus failure. (2) In the crushing hammer operation, the drill rod should always be vertical to the surface of the broken object. And make the rod is pressed to be broken object, broken should immediately stop crushing hammer work, in order to prevent air play. Continuous aimless impact will cause damage to the precursor of the crushing hammer and loosening of the main bolt, and can hurt the host itself in serious cases. (3) when crushing, do not use shaking rod, otherwise the main bolt and rod may be broken; Do not make the crushing hammer fall down quickly or hit hard stones, which will damage the crushing hammer or main engine due to excessive impact. (4) Do not crush in water or mud. In addition to the rod, other parts of the crushing hammer body should not be immersed in water or mud, otherwise the piston and other parts with similar functions will cause premature loss of the crushing hammer due to the accumulation of mud. (5) when breaking especially hard objects, should start from the edge, do not continuously beat more than 1min at the same point, in order to prevent rod burning or hydraulic oil overheating. (6) Do not use the protection plate of the crushing hammer as a tool to push heavy objects. Because the mining loaders are mainly minicomputers, their weight is light. If they push heavy objects, the crushing hammer will be damaged if they are light, and the lifting arm of the main engine will be broken if they are heavy, and even the main engine will overturn. 323/5000 (7) The operation is carried out when the hydraulic cylinder is fully extended or fully contracted, otherwise the impact vibration will be transmitted to the hydraulic cylinder and thus to the host. Maintenance of crushing hammer Because the working conditions of the crushing hammer are very bad, the correct maintenance can reduce the failure of the machine and prolong the service life of the machine. In addition to the timely maintenance of the host, the following points should also be paid attention to: 1, appearance inspection: check whether the bolts are loose; Whether the connecting pin shaft is excessively worn; Check whether the clearance between the drill rod and its bushing is normal, and whether there is oil leakage in the interval, indicating that the low-pressure oil seal has been damaged, and professionals should be asked to replace it. 2. Lubrication: The lubrication point of the working device should be lubricated before operation and after each continuous operation for 2 ~ 3h. 3, replace the hydraulic oil: the change of the hydraulic oil quality is different because of the different working environment. The simple way to judge the quality of the oil is to observe the color of the oil. When the oil quality turns bad is very serious, the oil should be let off, and then inject new oil after cleaning the tank and oil filter.

Gun head, also known as crushing hammer, stone crushing, crushing device, is one of the accessories often used by excavators, often used for mountain cutting, breaking road surface, house demolition, bridge demolition, mining crushing stones and other working conditions. The structure of the gun head is mainly divided into three blocks: the upper cylinder body (nitrogen chamber), the middle cylinder body (oil cylinder), the lower cylinder body, the three are connected by four full-body bolts. The upper cylinder is used to store low-pressure nitrogen, the middle cylinder is the piston, accumulator, oil seal, air exchange valve and so on, the lower cylinder has steel, flat pin, horizontal pin, inner and outer bushing. It can be seen from the above figure that the main structure of crushing hammer is divided into hammer body (movement) and bracket, in which the upper splint and the lower splint respectively protect the movement, and the drill rod is in direct contact with the material in crushing operation. The accumulator mainly plays a buffer protection role, which can prolong the service life of the crusher to a certain extent. Generally small crushing hammer or crusher hammer with diameter less than 10cm is not equipped with accumulator. Gun head is powered hydrostatic pressure, hydraulic drive piston run up, compressed nitrogen at the same time, when the piston to the reversing valve, hydraulic direction change makes the piston down, at the same time, influenced by nitrogen and piston weight force, so that the piston high-speed impact drill rod, the reciprocating motion of broken rock, concrete and other solid operations.
