Grinding in Ball Mills: Modeling and Process Control

2007-9-5 · Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

 · Re: Ball Mill Load & feed. Dear GKS, You are correct in stating that main drive kw only increase when less grinding media charge and small size of grinding media w.r.t. feed size and feed rate. However, it was to be stated in my reply that Kwh/t of material increases in chocked condition of the mill as there is no output from the mill. Warm regards...
