Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding.

Milling and grinding media are designed for ball milling and the grinding of bulk powder or granular materials into finer powder forms. Ceramic bead, hard metal shot, carbide balls, and other ball-shaped media are used. The hardness of the powder or bulk material to grind determines the selection of the media material.

The fine grinding mills are classified often into five major groups (i) impact mills, (ii) ball media mills, (iii) air jet mills, (iv) roller mills, and (v) shearing attrition mills …

INTRODUCTION Primary grinding mills as defined in this paper, are autogenous or semi-autogenous rotating, tumbling mills having a coarse feed with a top size usually varying from 150 to 300 mm (6 to 12 inches). Most frequently, the feed to these mills is the product of primary crushing plants but in some cases run of mine ore is used as feed such as at …
