Jul 17, 2021P = Shaft Power. E = Specific Power of Mill. Let's solve an example; Find the mill capacity when the shaft power is 24 and the specific power of mill is 6. This implies that; P = Shaft Power = 24. E = Specific Power of Mill = 6. Q = P / E. Q = 24 / 6.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Analysis of power draw in ball mills by the discrete. Apr 01 1999 The calculated power draft is maximum at about 50 ball load. According to Eq. 1 mill power is a function of ball mass M b and the distance between mill center and the center of gravity of ball mass r g. So as the mill filling increases M b goes up but r g decreases.

Power calculation is done by power consumed to do a job divided by throughput. We say KWhr / TON FEED. It is the power consumed by input feed to achieve a grind of mesh say 200# 80%. HOW THIS IS AFFECTED: Feed size: As feed size increases consumption will also increase as, larger feed size reduces input rate to achieve 200# 80%.
