Clinker Grinding Mill. The clinker, gypsum, and additive will next be fed into the grinding mill, to produce the desired type of cement. Essentially this is a rotating horizontal cylinder containing steel balls. The materials are crushed by impact and finely ground by attrition (friction) between the balls. Water sprays are passed through the ...

Cement Grinding: cement grinding is the final stage in Portland cement manufacturing. In this step, clinker will be ground in grinding mill to reach the qualified fineness of cement product. During the grinding, we usually add gypsum, fly ash and other raw materials into the cement to realize the different usage of cement.

Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.
