Vertical Coal Mill

Vertical Coal Mill, also known as coal mill, for superfine grinding of raw coal, soft coal specifically for cement, power plant, steel mill and other fields. Its special design structure and production process creates the higher production efficiency with lower energy consumption, less dust, lower noise than ball mill, which meets national standard of energy saving industry.


Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.

Air swept coal mill

Air-swept coal mill, also called coal mill, is an equipment used to grind and dry coal of various hardnesses. It is mainly used to grind lignite, coal, anthracite, coal gangue and other raw materials. It is mainly composed of a feeding device, a main bearing, a rotating part, a transmission device, a discharging device, a high-pressure starting
