It would then seem thatall charge that occupies between 25 and 50 per cent, of the volume of the mill will give the most satisfactory results. in an 8ft. 2.4 m. mill running at 22 r.p.m., with8,000lb, 12,700 kg. charge of 2in. 50.8mm. balls, there will be an average of about 1,000,000 blows per minute each of these blows will be equivalent to droppingin.

The volume percent of the ball mill occupied by the balls can be calculated from the relationship13 125hd 1314 question 11. aball mill having an inside diameter of 12 ft and an inside length of 14 it is to be used to grindopper ore.
