 Coal crusher is a kind of mechanical equipment which can break large particle coal into small particles at all levels according to the use requirements. It is mainly used in coal, chemical industry, power plant and other related industries. It can be divided into jaw type, hammer type, toothed roller type, compound type, grinding type and other forms. The products have experienced the process from import to domestic production.For example, in the coal industry, it is more suitable to use the Hubei type coal crusher. In the chemical industry and power plant industry, the hammer type and gear type are more used. As for the grinding type, the coal-fired boiler is mainly used. The composite products of hammer type and toothed roller are still in the initial stage and have not passed the market test, so the performance and reliability need to be improved.

 Working principle: take hammer type coal breaker as an example, the main working part of hammer type coal breaker is the rotor with hammer (also known as hammer head).The rotor is composed of spindle, disc, pin and hammer.The motor drives the rotor to rotate at high speed in the crushing chamber.The material is fed into the machine from the upper feeding port and crushed by the impact, impact, shearing and grinding of a high-speed hammer.In the lower part of the rotor, there is a sieve plate. The particles smaller than the mesh size in the crushed materials are discharged through the sieve plate, and the coarse particles larger than the mesh size are retained on the sieve plate and continue to be hit and ground by the hammer, and then discharged out of the machine through the sieve plate.Hammer crusher is suitable for crushing various brittle materials.The crushed materials are coal, salt, Baiya, gypsum, alum, brick, tile, limestone, etc.
