Laboratory MillsBall mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length to times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance.
