The operating principle of the ball mill
Energy consumption for ball mills is a function of many factors: the physical properties of the ground material – its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc. Ball mills have low efficiency – no more than 15%. Energy is mainly consumed on the wear of grinding balls and ...

Ball Mill Design/Power Calculation
The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. 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.
THE LURE OF GOLD (continued)
Also under construction that summer was a mill, located at 40 feet above sea level and adjacent to left bank of Nuka River. The mill building contained a small Blake jaw crusher; a Worthington overflow-type, 5' x 5' ball mill; a drag classifier; amalgam plates; and a concentrating table. Its capacity was 40 tons per 24 hours.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
