Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls. Types of ball mill

The effect of slurry rheology on fine grinding in a

The effect of slurry rheology on fine grinding in a

Abstract The kinetics of slowing down of breakage rates for fine wet grinding of 20 30 mesh quartz fraction was investigated as a function of slurry concentration in a laboratory batch ball mill. It was discovered that the slowing-down effect occurred to all particle sizes in the charge and at any slurry concentrations even for very dilute conditions.
