9.3.2.1 Coal Hammer Crusher Operating Principles. Hammer mills are primarily steel drums that contain a vertical or horizontal cross-shaped rotor mounted with pivoting hammers that can freely swing on either end of the cross. While the material is fed into the feed hopper, the rotor placed inside the drum is spun at a high speed.

Coal mill is also called coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are air-swept ball mill and vertical roller mill.. At present, most cement plants use coal as the main fuel in the clinker production process.

SUPPORT CONTROL SYSTEM. The various functions of the powered supports are controlled by an electro-hydraulic control system. The simplest method utilises a control valve mounted on each support which is used to operate the functions of that support (lowering and raising legs, support advancement and conveyor push).
