Solved Please Answer ALL. Thanks. 1) The ore fed to a rod
The p80 of feed to the mill is 22 mm (f) and the p80 of the product from the mill is 0.140 mm (p). Calculate the work (in kW/tonne) required to grind the ore to the product size. 2)A ball mill with an internal diameter of 2,600 mm is operated at 75% of the critical speed. At what speed in revolution per minute should the mill be operated at.
