Coal mill. The coal mill uses coal, coke or grinded pet coke with different size of balls. Larger sized balls are used for impact grinding and the smaller balls are used for attrition grinding. Cement mill. This is the final step in a cement manufacturing process. In this step, the clinker is ground together with additives in a cement mill.

Fuel is combusted to produce heat for the clinker production process; coal is the traditional fuel used in China's cement industry. The raw coal from the stockyard is crushed in a hammer crusher and fed to the coal mill. The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator.

Silo/filter probes for your coal mill system. Highly combustible coal dust poses a serious hazard. CO builds up in coalfilled silos and in cyclones or bag houses that are not being used, while imprecise O2 levels in inert coal mills can also present a significant danger. In either situation, selfignition is a real possibility.
