Cutting mill

Cutting mills are mills commonly used in laboratories for the preliminary size reduction of soft, medium-hard, fibrous and tough materials.

A rotor inside the mill revolves at high speed. The rotor is equipped with special cutting plates which comminute the sample material. Different rotor geometries make mills adaptable to different material properties (medium-hard, soft, fibrous or elastic materials). Such mills are suitable for reducing rubber, leather, plastics, grains, dried meat, bones, vegetation and other substances.

In elemental analysis, cutting mills should be used with care, since they can contaminate finely-reduced samples with metals from the blades and screens.
