HOW BALL MILL WORKS? - energosteel

10/10/2016  The amount of milled pieces also gradually decreases as approaching to the place of unloading and this reduces energy consumption for grinding. Should be noted, the productivity of ball mills depend on the drum diameter and ratio between the diameter and length of the drum. At the short ball mill grinding is a more rough and for grinding fineness a lot of material has to be returned from ...

ENERGY SAVINGS AND TECHNOLOGY COMPARISON USING

grinding can be achieved at lower energy consumption. In ball mills, energy savings vary from 10 per cent to 40 per cent compared to 25 mm media. A regrind ball mill with a mix of small grinding media can be as energy effi cient as an Isa Mill charged with 2.5 and 3.5 mm beads. In vertical stirred mills, energy savings vary from 30 per cent to 60 per cent. To carry out the same fi nal grind ...

Ball Mill Critical Speed - Mineral Processing Metallurgy

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...
