Continuous Grinding In A Small Wet Ball Mill Part Iv A

Abstract txx influence of changes in grinding media load and density on the grinding behaviour of trace quantities of quartz within an environment of calcite in a small continuous wet ball mill have been studied using (a) ball loads ranging from 45% to 100% of the standard load of 1-in. balls, (b) a standard load of 1-in. pebbles and (c) standard loads of equicylinders with specific gravities.As with dry milling there should be at least 25% liquid to fill the void space plus a bit more to insure the balls are striking product and not each other. of course the surface tension of the liquid used will greatly affect the ability of the solids to be both suspended in the liquid and to form a film on the grinding media. product viscosity in a factor in wet.
