2017年4月25日 Rod mills are normally operated at 50 to 65% of critical speed. This allows the rods to tumble in a cascading-type pattern instead of cataracting, which tends to tangle the rods. Pulp densities usually range from 60 to 75% solids with finer feeds requiring lower pulp densities, although optimum conditions are ultimately dictated by the ore itself.

Ball Mill Explained saVRee
For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged. Pulp is usually 75% solid (crushed ore) and 25% water; pulp is also known as ‘ slurry ’.
