The coal hammer crusher crushes materials by the collisions between the high-speed hammer and materials, and the coal hammer crusher features in its simple structure, high reduction ration, high efficiency, etc. The PC type coal hammer crusher is developed for both dry and wet crushing of brittle and medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and petroleum chemical industries.

Operation and maintenance of coal hammer crusher:

1. The frame and the liner should be checked preferentially to tighten  the availability of loose bolts and other bolts, whether they are good for running or not, check and remove the material if there are some material in the crusher machine.

2. While power on, attention should be paid enough to check and make sure the material is evenly feeding, no excess, the particle size is not ultra-light, and any problem should be solved in time. Avoid iron and other materials cannot be crushed feeding into the crusher. It brings serious damage to crushers if feeding large blocks iron or other materials cannot be crushed.

3. Crusher hammers are the most easy wear parts, and it can be reuse by changing the other side. When replacing hammer, it should be weighed individually. According to the weight of hammers to form a single group and each group has the same weight. The weight difference of the hammerhead and the axis pin should be less in 0.05KG to ensure the smooth operation of the rotor. When overhaul, hammers should be packed to do the whole rotor balancing test which makes the extension of life and safety play an active role in running. While replace the hammers, pay attention to whether there exists crack and trachoma on the hammer, unqualified hammers cannot be use.

Operating principle of coal hammer crusher:

The motor drives the rotor to rotate the hammer crusher with high speed through the belt, and on the rotor there are a series of hammers. When the materials get into the working area of hammers, they are crushed by the rotating hammers of the coal hammer crusher with high rotation speed, the products which are crushed to meet the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushed area by the hammers of the coal hammer crusher for being re-crushed until they reached the required size. This machine can be adjusted according to user space grate section, change the particle size, to meet the different needs of different users.
