The breakage mechanisms in stirred mills – regardless of the mill orientation – are typically described as abrasion and attrition (Gao and Forssberg, 1995, Sinnott et al., 2006, Wills and Napier-Munn, 2006, Ye et al., 2010), or more simply "shear" breakage (Radziszewski, 2013).The dominant breakage mechanism in ball mills is generally …

How Overflow Type Ball Mill Works. Material Feed: The raw material is fed into the mill at one end and travels through the mill by rotation. The feed enters the mill at a specific rate, ensuring a controlled grinding process.; Grinding Process: As the mill rotates, the grinding media crushes and grinds the material into a fine powder. The wet …

The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, and secondary grinding requiring 5-2 cm. Concha et al. (1988) have developed a method to calculate ball mill charge by using a grinding circuit simulator with a model of ball wear in a tumbling mill.
