Ballmill Design - Power Draw

Summary

An interactive design tool for determination of ballmill power draw.

Notes on Ball Mill Design - Power Draw

  • Power Draw is steady running power requirement ... ignoring drive-train losses and startup loads.
  • Power Draw is reduced for regrinding ... ie. if 1.5 < (Feed Size/Product Size) < 3.0
  • 105 < Feed Size < 10000 microns
  • 20 < Product Size < 75 microns
  • 3.0 < Mill Diameter < 5.5 m
  • 3 < Mill Length < 10 m
  • 1 < Vertical Drop < 5 m (top of shell to lowest discharge point)
  • RPM < 30
  • 0.3 < Ball Vol Fraction < 0.5
  • Ball Depth measured from top of shell to balls
  • 5 < Max Ball Dia < 20 cm
