In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. Silica ore was used as the test material.

2019-8-24 · Application: Energy saving mining ball mill is a key equipment in beneficiation plant.It is widely used in ore dressing production line such as Gold ore, Cooper ore, Magnetite ore, Antimony, Calcite, Kaolin, Mica, Clay, Bentonite etc Ferrou metal or Nonferrous metal materials.

ball mill charge calculation residentialpainters.co.za. How To Calculate Charge In Ball Mill . Ball milling Digitalfire. A ball mill is simply a container that is filled with pebbles (either of porcelain or stones e.g. Flint) into which a charge (powder or slurry) is put and that is to determine the amount of balls needed, distribution of ball

Ball Size Distribution. As the mill starts, grinding action and throughput increases. However, after reaching a critical speed, the mill charge clings to the inside perimeter of the mill. Under this conditions, the grinding rate is significant reduced or stopped. All mills must operate less than Critical Speed
