Cutting mills are ideal for comminution of soft to medium-hard, brittle, fibrous, tough or temperature-sensitive materials as well as plastics and for preparation of heterogeneous mixtures.

he samples are comminuted by cutting and shearing forces, and the selected sieve cassette determines the final fineness. Various knife geometries and replaceable blades ensure maximum flexibility and durability. Cutting tools of various steel types as well as of hardmetal tungsten carbide can be used for controlling the abrasion problems.
All types of grinding cause frictional heat, therefore it is important when grinding plastic and rubber to also consider options such as cyclones, liquid nitrogen and freezing to reduce the frictional heat and/or achieve more brittle material in the grinding chamber or as pre-treatment before grinding.
Different laboratory cutting mills
-
Pulverisette 29 is ideal when regularly grinding small sample quantities of materials such as plastics and other materials with a low specific density.
-
Pulverisette 15 is ideal for the comminution of dry sample materials with soft to medium-hard consistency, for fibrous materials or cellulosic materials.
-
Pulverisette 19 is the best choice for the most common applications, strong and powerful for harder materials and also with a wide range of variable rotational speeds for universal use.
