This is the power of the shaft given in horsepower. Since 1 kW = 1.341 horsepower, 0.1008 kW in horsepower will be given as: 0.1008 kW × 1.341 = 0.135 horse power. Using a factor of safety of 1.5for the design, the motor horsepower required will be = 1.5 × 0.135 = 0.2025 horse power.

### Ball Mill - an overview | ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
