Cutting mills are particularly well suited for comminution of soft to medium-hard, fibrous or tough materials (including plastics). They are frequently also used in the preparation of heterogeneous substance mixtures and for sample preparation for RoHS and WEEE analysis. In this type of mill, samples are comminuted through cutting and shearing. The fineness is determined by a sieve insert.
Various knife geometries and replaceable blades ensure maximum flexibility and durability. Grinding parts of various steel types as well as of hardmetal tungsten carbide can be used for controlling the abrasion problems.
All grinding parts can be removed for cleaning in just a few seconds without tools – unbeatable fast, simple and efficient!

The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm. Material is transferred from the center roll to the apron roll by adhesion. The dispersion is achieved by the shear forces generated between the adjacent rolls. The milled material is removed from the apron roll by a knife that runs against the roll.
