2022年11月1日 In numerous cement ball mill operations (Genc, 2008, Tsakalakis and Stamboltzis, 2008, Altun, 2018, Ghalandari and Iranmanesh, 2020), the ratio of maximum ball size to minimum ball size for coarse milling compartments lies between 1.3 and 2.0,
the ball mill had an average production rate of 190tph with a specific electrical energy consumption of 35.5kWh/t. Its operational issues included: • oversized limestone • worn
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") rath
