Grinding raw material and clinker causes considerable wear to the grinding mill. Starting the mill direct-on-line stresses the mill and the gearbox, increasing the risk of gearbox failure and shortens the lifetime of mechanical equipment. VSDs help optimize the mill speed to match the material flow, thus minimizing the wear of the grinding mill.

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...

A Ballpeb mill is a secondary ball mill having either one or two compartments. This mill is specifically designed for operation in series with a Preliminator mill, or as a finish grinding mill with small size feed. Ballpeb mills will produce a finished product from relatively fine feed in open or closed circuit.
