The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test. The pulp volume of the pulp in the mill is then calculated using the mill discharge density before dilution obtained during the sampling.The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test.

The density of solid can be estimated if you know the composition by weight or volume of each component in the solid and the respective solid densities.Also, the uprising velocity in the mill can be controlled by a recycle pump to affect the product size distribution, prevent over grinding, and reduce the circulating load from the cyclone. Final product size is a factor of applied grinding power, flow rate, and slurry density.

At dilute slurry conditions, particles appear to reside in the ball mass, but they tend to migrate to the mill periphery forming a deposited layer at concentrations greater than 45 vol. solids.

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. This effect caused a change in the circulation path of moving balls, asThe effect of slurry density on the dynamics and grinding behavior of a batch ball mill was studied using quartz as a test material.
