### How to Calculate Load Torque & Motor Power

2006-3-4 The sum of resistances = tractive pull. The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5) Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and so on.

### Effect of lifters and mill speed on particle behaviour

2017-5-1 The torque and power of a ball mill usually increase with an increase in mill speed when no lifter exists in the mill (N l = 0 or H L = 0 mm). Usually, the slope is extremely small. The torque and power curves become close to the curve corresponding to no lifters (N l = 0 or H L = 0 mm) when the lifters are few and low. This condition indicates

### Ball Mills an overview ScienceDirect Topics

Ball mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.
