## 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") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the m…Ball Mills | Industry Grinder for Mineral Processing,,Jan 30, 2018· Ball Mills 【Capacity】 From 0.2-90 T/H 【Advantages】Designed for long service life, minimum maintenance, can grind and homogenize mineral ores down to the nano range, large volume of processing capacity 【Max Feeding size】 <25mm 【Discharge size】0.075-0.4mm 【Types】overflow ball mills, grate discharge ball millsCement Ball Mill - JXSC Machine,The equipment of ball mill used in cement plant includes vertical cement mill, roller press and ball mill, etc. The cement ball mill in cement plant is usually divided into 2-4 silos, the most representative of which are the “new type of high fineness cement ball mill” and “open flow high fineness cement ball mill”.Ball Mills - an overview | ScienceDirect Topics,The critical speed n (rpm) when the balls are attached to the wall due to centrifugation: Figure 2.7., Ball mills are rated by power rather than capacity.
