The capacity of a system depends on the grindability of the clinker and the fineness it is ground to. Picture 6 shows the ...
All types of cement grinding mills such as cement ball mills, vertical roller mills, roller presses, and various related equipment form a highly efficient production line. Closed circuit grinding systems equipped with an O-Sepa separator are more efficient especially when the grinding mill is a cement vertical mill.
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.
