    Crushing and breaking. Run-of-mine coal must be crushed to an acceptable top size for treatment in the preparation plant. Typical crushing and breaking devices are feeder breakers, rotary breakers, hammer mills, and roll crushers. Sizing. Different cleaning processes are used on different sizes of coal. Therefore raw coal entering the plant will be screened (sieved) into three or four sizes. Clean coal is rarely

  • Crushing Methods and thier Classification Mineral

    With an open crushing cycle, the product is fed to the crusher only once, with a closed crushing cycle, the material from the crusher goes to the screen, where it is sorted and large pieces are returned to the next crushing cycle, and small pieces are returned for further processing. With a closed crushing cycle, the best result is achieved, since the resulting granulometric composition is uniform, as well as energy consumption and wear of the parts of the crusher
