Coal mill is the equipment used for grinding and drying coal with different hardness and it is mainly composed of feeding device, principal axis, rotating the part, transmission part, discharging part, highpressure starting device, and lubrication system. It is widely used cement, building material, thermal power generation, metallurgy, and chemical industry.
This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coalfired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
on 70 of the coal passing through a 200 mesh screen. Mills are capable of grinding harder coal with higher percentage moisture content and can reduce the product fineness in excess of 90 passing a 200 mesh screen at a reduced output capacity. The feed size of the coal to the mill should be precrushed to 1 top size. Available capacity size
The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber. The impeller is a cage with a set of blades installed around its outer ring. It introduces a secondary classification by the collision effect in addition to the primary classification by centrifugal force 11 , 12 , 13 .
All internal mill surfaces must be smooth so that the swirl of the coalair mixture may enter and leave the classifier without spoiling or turbulence caused by double layer tiles, welded pad eyes

To grind coal to fine powder for further firing at the huge huge burners fitted in the water walls of boilers in the coal fired thermal power plants mainly to heat water and convert to high pressure, high temperature steam, steam to be fed in turb
Hardgrove Grindability Index short HGI is a measure for the grindability of coal. Grindability is an index, therefore it has no unit. The smaller the HGI, the harder is coal texture and less grindable is the coal. Grindability is an important factor for the design a coal mill. As grindability depends on many unknown factors, HGI is determined

Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throats flowshaping contour, enables recirculation patterns that extend into the furnace.
The ATOX Coal Mill handles feed materials with less than one percent moisture and up to 25 percent moisture, where abrasiveness and stickiness is not an issue for grinding. Longlasting durability. The materials used to produce the ATOX Coal Mills segmented wear surfaces are durable and therefore, last longer.
