The influence of mill speed and pulp density on the
The extra power input achieved by increasing the speed does not seem to have any effect and does not result in a finer grind. 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 ...
