WebBall Mills or Ball-Medium Mills grind through impact of a grinding media such as balls, rods, etc. (see SPEX SamplePrep's Mixers and Mills and technical notes for more information). Vibratory or Shaker Mills use high speed vibrations and grinding media to combine multiple grinding forces to reduce materials to fine powders.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be ...
