Ball Mill Loading (dry milling) When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product. Charging a Dry Mill The general operation of a grinding mill is to have the product impacted between the balls as
The media diameter of 60 mm and 50 mm were supplemented for the optimization and verification test of media proportion. The dry grinding experiments were operated in a ball mill (460 #215; 600 mm) with steel ball media at mill speed 47 r/min, spacefilling factor 30%, and material ball ratio

#0183;#32;Dry batch milling of a silica ore. In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. The ball mill, liners and grinding media employed were made from stainless steel.
As it can be seen from the results grinding media shape effect particle size and power draw for ball mills. Spherical balls have nearly %27 finer product than worn balls.
