The cutter head, also known as hammer head, is the main vulnerable part of the crushing shaft, and it is also the part that bears great impact force when crushing coal. There are castings and forgings on the market, but the castings bearing strength is small and the service life is short. Blade was covered a layer of wear-resisting layer forging and become, blade and blade both use a special fastening bolt and nut set, blade bolts and nuts with locking washers, when wear to a certain situation or cracks have appeared, should change in time, otherwise will make the blade are installed on the part of the blade is damaged, and can no longer be tighten blade on the blade holder. The broken shaft without cutting teeth will lose its balance, and the strong vibration will shorten the service life of the broken shaft sharply. Shuangzhi coal machine for many years focused on the scraper conveyor, transfer machine accessories, crusher accessories system repair, products sold to the major mining areas, more information please click on the official website of Shuangzhi coal machine or call to inquire the factory investigation
The crushing machine series of mine scraper conveyer is mainly used in combination with the transferring machine and complete the conveying task of underground comprehensive mechanized coal mining with belt conveyer, scraper conveyer, shearer and hydraulic support. The models of mine crusher are PCM, PEM, PLM, etc. They are respectively represented as hammer crusher, jaw crusher, wheel crusher, etc. According to different working face and production capacity of mine, different crushing capacity of crusher is required. For example, PLM3000 wheel crusher has crushing capacity of 3000T /h. PLM4000 wheel crusher with crushing capacity up to 4000T /h. The crushing shaft group is the main component of the crushing coal and gangue. Using the broken shaft set higher rotational inertia stored at rated speed kinetic energy by installing group on the shaft of the broken blade and the broken material short contact time and impact break coal formation, again by cutter tooth and scraper chain, crusher, the speed difference between further to crush was broken coal, so as to achieve the goal of broken coal. Shuangzhi Coal machine focuses on the production and manufacturing of spare parts of scraper machine, transferring machine spare parts and crusher spare parts for mine. It is located in Zhengzhou with developed logistics. At present, it cooperates with major mining areas all over the country.

Common hammer head hammer head materials are: high manganese steel, low carbon alloy steel, high chromium cast iron. High manganese steel has better toughness, better technology and lower cost. But the processing hardening of high manganese steel requires higher processing technology. If the impact force is not enough and the contact stress is too small, the surface cannot be hardened. Low carbon alloy steel has high hardness and toughness. At the same working strength, the service time is twice that of high manganese steel. High chromium cast iron has poor toughness and is prone to fracture. High chromium cast iron is usually used as hammer handle on the head of high manganese steel and low carbon alloy steel to make it have hardness and toughness. The quality of manufacturing process is to determine the service life of the hammer head. If there are shrinkage holes or cracks on the surface or inside of the hammer head, it will reduce the performance of the hammer head and even cause fracture in the operation process, affecting the working efficiency. In the manufacturing process of hammer head, forging and heat treatment process should be strictly controlled, and strict quality inspection process should be established. Hammer heads of different structure and geometry have different performance after heat treatment and forging. Generally speaking, the thicker the hammer head, the larger the size, the less easy to penetrate. However, it is limited to change this situation through reasonable heat treatment and forging, so it is still necessary to optimize the structure and shape of the hammer without affecting the use effect. In general, the rotor speed of the broken shaft group is high, the greater the impact force on the hammer head, it can be better impact hardening. But also can cause the hammer head service life to reduce, the crusher power consumption is too big. Therefore, a reasonable speed should be set. If the clearance between crushing shaft rotor, grate, crushing plate and feeding roller is too small, it will lead to the blockage of coal. If the clearance is too small, the crushing effect and efficiency are too low. Hammer head crusher in the use of time, often adjust the clearance between the parts, so that it in the appropriate range. The shape and quality of hammer head directly affect the yield and service life of the crusher. When buying a crusher hammer head, pay more attention to the above mentioned factors, choose suitable for toughness hammer head. Henan Shuangzhi Machinery Equipment Co., LTD. Produces hammer head of crusher, crushing shaft group, scraper conveyor accessories. Welcome customers to purchase.

The crushing shaft is composed of crushing shaft, cutter tooth base, cutter tooth, flat key, bearing, seal and fastening bolt. The strong rival of coal "big block" is broken shaft group, today we are going to introduce this "strong rival"! Trough crusher is used with the transfer machine, using the high speed rotating hammer head to impact and squeeze large raw coal, so as to achieve the required particle size. The crushing shaft assembly is the key component of the crusher, which requires high precision and high stiffness. The middle part of the spindle is equipped with hammer head, which is directly involved in impact crushing. Its performance is the key. Due to the large impact load of the hammer head, high rotation speed, the use of mining is extremely bad, so the performance of the hammer head largely determines the reliability of the crusher. Main parts function, structure characteristic and installation and maintenance of broken shaft 1. The rotating part of the crushing shaft assembly shall not contact with any other parts in the box body. 2. The distance between any particular point of the rotation part of the crushing shaft set and the side wall of the crushing box is equal on the circumference of the crushing box. 3. The fastening bolts between the cutter body and the cutter tooth base shall not be loosened, and the cutter body shall not be cracked. 4. Manual rotation of the crushing shaft should be smooth and sound. 5. There is no bump mark in the belt groove on the pulley. 6. Prepare for complete machine test in coordination with other parts.
