Designed to deliver exceptional levels of performance and value, David Brown Santasalo ball mill drives are optimised for primary and secondary grinding applications. Extensively field tested and proven in harsh cement applications, our mill drive gearboxes cover all grinding applications up to 10 MW per drive

An experimental laboratory scale ball mill available at the University of Lubumbashi was used in this research work. The ball mill measured 0.305 m in diameter and 0.127 in length. It was driven by an asynchronous motor rated with power close to 10 kW. A schematic of the experimental laboratory ball mill used is shown in Fig. 3

Oct 26, 2018 Oct 26, 2018 Principles of Grinding in Ball Mills. Action inside a Ball Mill drum is not a haphazard process. Stirring is not random nor is the throwing of the charge. There is a very specific operating speed for the most efficient grinding. Depending upon the Mill’s speed, there is a point in which the load along the wall of the cylinder will break free
