The effect of slurry density on the dynamics and grinding behavior of a batch ball mill was studied using quartz as a test material. it was found that slurry density determined the distribution of solid charge in the mill, with migration of particles from the tumbling zone to the mill periphery as solid concentration was progressively increased.
Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. it will control the grind in two ways. it affects retention time and helps distribute the ore through
