# calculate ball information ### Ball Mill an overview | ScienceDirect Topics

Conical Ball Mills differ in mill body construction, which is composed of two cones and a short cylindrical part located between them (Fig. ).Such a ball mill body is expedient because efficiency is appreciably increased. Peripheral velocity along the conical drum scales down in the direction from the cylindrical part to the discharge outlet; the helix angle of balls is decreased and ...

Note the starting position of the tape and count the amount of times the ball has rotated using fractions, not hours. Take the total amount of rotations and multiply by 4. This equals hand revs. For example, the ball started at 9:00 and ended at 3:00, passing past 9:00 three times. This would result in 3 1/2 rotations. 3 1/2 X 4 = 14 hand revs.
