The feed material, which is usually 4 to 8 mm in size, enters the grinding zone via the inlet chute at the mill door. There it is ground between the axially adjustable stator disc and the grinding disc rotating at high peripheral speed according to the shear-cutting principle. The grinding takes place in stages via a grinding gap that narrows from the inside to the outside. The finely ground product leaves the grinding zone through a precisely defined gap.

Where an exact top grain limit is required, the mill can be operated in a circuit with a suitably designed screening machine. The oversize is returned directly to the grinding zone. Most plastics can be finely ground at ambient temperature using this technology. Cold grinding is used for temperature-sensitive substances.
