between the crushing elements (mantle and concaves), finally exiting the crushing chamber at the bottom under the influence of gravity. The crushing elements, mantle and concaves are made of high wear resistant material. The crushing gap is adjusted by hydraulically lifting or lowering the main shaft by the hydraulic cylinder.
Coal crushing can include a two stage process, dependent on deposit size. Coal is crushed in a feeder breaker, a chain conveyor that breaks the biggest lumps. Coal size is further reduced through a sizer. Screening is used to separate different sizes of crushed coal. In this process, coarse and fine coal is separated to accommodate specific ...
