Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material for blending. Most of the material is usually ground finer than 90 microns - the fineness is often expressed in terms of the percentage retained on a 90 micron sieve. Once the the raw materials are ground fine enough, they are blended in ...

Mills belong to a class of equipments that accomplish comminution of materials in the fine range. There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns.

The cement clinker manufacturing process can be divided into mill-on and mill-off modes according to the raw mill operating conditions ( Li et al., 2019, Zheng et al., 2012 ). When the raw mill is running during the mill-on mode, the flue gas from the precalciner passes through the raw mill into the dust collector before being emitted.
