Coal grinding mill of coal mill for coal production line

Coal mill is the key equipment for re-crushing, it is widely used for dry or wet powder grinding operation of ore grinding before dressing ferrous and non-ferrous metal, raw material or finished product of cement, chemical industry, novel construction material, refractory material, etc.

Coal  mill is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control).

Working principle of coal mill:

As coal powder is the most important fuel in the power plant, The plant owners need coal mill or coal pulverizer to grind the coal to micro powders.
Raw coal (crushed) is fed through hopper at the top of the coal pulverizer and falls down to grinder ring to be pressed, crushed and milled into pieces by rollers. After the first crush, coal powder fall into the second and third layer. The pumping of the high-pressure centrifugal blower put the outside air into the coal mill. The coarse coal powder will be brought into the classifier.

General in the complete coal powder production line, Crushing is the first step, using the coal crusher to crush coal into small particle. These small coal particle is grinded into powder by coal mill. The whole system consist of main coal crusher, coal mill, blower, dustpan elevator, electro-magnetic vibrating feeder, impulse dust cleaner, cyclone collector device, classifier, high-pressure motor and muffler.

Application of coal mill:

Coal mill pulverizer used in cement plant:
Coal mill (coal pulcerizer) is the essential machine used in cement plant, because coal is the important raw materials in cement production line. Coal powder after grinding by coal mill enter into the rotary kiln toghter with cement raw meal for burning.

Coal powder has special strict demand in fineness. The finished size is 0.0445mm.
