    Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other.

  • Ball Mill RETSCH powerful grinding and homogenization

    The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming effects. These ball mills are also suitable for mechano chemistry.
