Simulation and optimization of a two-stage ball mill

7/1/2016· In this study, a two-stage ball mill grinding circuit currently run at the molybdenum mine in Jecheon, Korea, is investigated. The concept of this work is based on the kinetic grinding model, with the methodology proposed by Austin, Klimpel and Luckie . This method is not based on specific energy, but is capable of predicting the mill performance of various grinding circuits.

Stage 4: Finish Process Cement Production

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.
