2009-8-26 · The particles size distribution slope is not affected by the mill speed (see Graph 2) as the curves are mostly overlapping. Density These tests were done with a ∅0.82 x 1 m grate discharge mill with a 30 mm graded ball charge and a 30% filling degree. The mill discharge pulp density was increased from 68.8% to 75.9% solids.
