Grinding kinetics of quartz and chlorite in wet ball milling

01-01-2017· A typical study of grinding was carried out by Venkataraman and Fuerstenau using a 1:l mix of calcite and quartz in a tumbling ball mill. The results showed the breakage rate was first-order for both calcite and quartz when ground alone or as a component in a binary mix. However, the breakage rate of each component in the mix changed.

Identification of Optimal Mill Operating Parameters during

ball filling during quartz grinding and the scale-up of lab-oratory mill results to full-scale. 2. Theoretical background Let’s consider a mass of material M in a ball mill that after breakage needs to be divided, by using x i screens, into i + 1 narrow size classes. Normally, for a size class i bounded between two successive screens x i and x i+1 con-
