In the charge, the center of gravity is shifted from the rotational center of the mill system, and its motion is induced by rotation of the mill. At the same time, the charge creates a torque in the mill system. Breakage of ore particles and wear of liners/ball media are closely linked to this motion. To study these phenomena in a physicallyImproved Productivity in Mining. SafeSet Torque-limiting1 Ball Mill 2 TBM Due to the varying hardness of soil and rock layers, torque peaks are hard to predict. Excessive torque levels can occur particularly the torque creates a shock load for the gear box and could cause signiﬁ cant damage and downtime.

ids showed that maximum torque occurred at a mill load volume equivalent to fill ing of the void space between the balls. Increasing slurry percent solids in creases torque until the slurry becomes too viscous to permit cataracting of the ball-ore load. At this point torque de creases.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23%Calculation Of Load Torque Gold Ball MillsHow To Calculate Torque Load Of Ball Mill.
