The basic parameters used inball milldesign(powercalculations), rodmillor any tumblingmillsizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desiredmilltonnage capacity DTPH, operating % solids or …
ball mill power load relationship. The proper operating speeds of ballmills vary inversely as the squareroot of the diameters The proper operating speed of a ballmill increases as the size of the ball load increases Due to interference between the balls the volume of the charge should not be over 60 per cent of the volume of the mill
Calculating a grinding circuit’s circulatingloadsbased on Screen Analysis of its slurries. Compared to %Solids or Density based Circulatingloadequations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around theball millor rodmilland hydrocyclones, screen or ...

Theball millis the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed inball mills.
Jan 01, 2000· The target ball volume is 38%, which translates to a target power of 2,145 kW (_+ 32 kW depending on liner life). The ABC is setup to add 100 kg increments as required, typically 10+15 times per day. The maximum BWR allowed by the control program is 50 g/kWh and the minimum is 30 g/kWh.

Ball millstumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed toball mills(dry basis) is typically 75 vol.-% ore and 25% steel. Theball millis operated in closed circuit with a particle-size measurement device and size-control cyclones.
