densitys in a ball mill

Slurry density effects on ball milling in a laboratory ...
1989121 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.

Pulp Densities Within Operating Ball Mills  OneMine
The ball mill made about one revolution after the power was turned off, and just as soon as the mill stopped, a spout was placed at the discharge trunnion and all of the pulp that flowed out of the mill was caught in tanks. The manhole in the mill was then opened and the whole mill charge dumped into other tanks.

The influence of mill speed and pulp density on the ...
2009826 The pilot mill is also equipped with a sensor measuring the ‘ball and pulp toe and shoulder angles’ (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73% solids as the total media angle does not change.

How Mill Load/Charge is Estimated  Grinding ...
20211117 Sag mills in the gold and copper operations would vary from 6% 15% and are normally grate discharge types in most cases the densities of the slurry in the mill is over 65% and that goes for ball mills also. Off course you have a upper limit or the balls will "float" out. Higher densities allow better grind and increase residence time in the mill.
