Ball Mill Understanding & Optimisation Mill (grinding
This book throws new light on the internal mechanics of mills. It covers among others the following aspects Ball, tube, rod, pebble, batch, grate discharge, trunnion overf1ow, hardinage and airswept mills open and closed circuit grinding dry and wet milling contamination of products.For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,.
