Maintenance management is an essential part of effective operation of a coal preparation plant. The key metric is: overall equipment effectiveness can be applied to any coal-processing facility to measure and sustain performance. The maintenance management system consists of a framework of 3M: man, machine and methods.
The unit processes in coal preparation plants vary, but the following sequence of steps is typical. 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.
