Wet grinding of CaCO3 with a stirred media mill: Influence,

Unlike in the case of tumbling ball mills, grinding in stirred media mills is not limited by the critical rotational speed because the mill wall is stationary and the grinding media are kept in rapid motion by an axial stirrer. This enables high-energy intensity, which isCement Grinding in Ball Mills and Vortex Layer Devices,,Grinding cement in ball mills. The principle of the ball mill operation is simple: it consists of a rotating drum and grinding media (cylinders, balls etc). The material is placed into the drum which starts rotating.

Cement mill - Wikipedia

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs,Request for feedback for a Two Chamber Cement Mill Ball,,Re: Request for feedback for a Two Chamber Cement Mill Ball Charge and Longitudinal Sieve Analysis.
