Coal Mill


Strong adaptability, reliable performances and continuous production

A coal mill is the important auxiliary equipment for coal-powder furnace. It has three methods to crush the coal lumps and to grind them into powders, that is, crushing, impacting and grinding.
Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is fed into the coal mill via an inlet pipe so that the coal mill can pulverize the coal into particles.

Materials:Coal, cement clinker, limestone, calcite, dolomite, talc, etc.

Product Advantages


The use of new wear-resistant materials greatly improves the service life of wearing parts.

The PLC control system can be selected to improve the automation control level of the grinding mill.

The coal mills have closed structure, so there is less dust spill-over, and it is beneficial and friendly to the surrounding environment.

ZENITH’s coal mills have an excellent balance between productivity and energy consumption. Users can get higher capacity under the premise of low energy consumption.

Working Principle of Coal Mill


As the mill rotates, steel balls work to grind the coal. The mill rotates approximately once every couple of seconds.
The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of coal is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer ones and sent back for further grinding. When final products reach the fineness standard, they are discharged out of the mill.
