Ball Mill Loading - Dry Milling - Paul O. Abbe

Charging a Dry Mill – The general operation of a grinding mill is to have the product impacted between the balls as they tumble. If there are insufficient solids in the mill then the media will strike itself and generate excessive media wear. If too much product then the solid may buffer the impact too much. As with most of the independent variable in ball milling it is best to do some ...

Grinding Media - Growth Steel

Media to media contact for rods mills is linear rather than point to point (as with balls) and are much heavier. The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. This leads to a narrower size distribution and significantly less slime compared to ball mills.

Ball mil design calculation? Yahoo Answers

31/03/2008  The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill speed, rpm. The actual motor energy consumption is 5-10% greater than this due to mechanical losses in the motor and gearbox.
