    REtSCH Mixer Mills are used for the pulverization of hard, medium-hard, soft, brittle, elastic and fibrous materials. The sample feed size depends on the mill and can be as large as 8 mm. If the feed size is larger than this then the sample must first undergo preliminary size reduction. Milling – Jaw Crushers – Rotor Mills – Cutting Mills
