slurry density for ball grinding
Slurry density effects on ball milling in a laboratory
Dec 01, 1989 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.
