The Mikro® UMP Attrition Mill is high speed cutting mill designed for the fine size reduction of plastics, polymers and fibrous materials that do not respond well to other forms of impact milling. It is designed to grind heat sensitive and soft materials without liquid nitrogen or conditioned air.
The raw material enters the grinding zone from a feeding device through the centrally located feed inlet. Size reduction takes place between the adjustable stator plate and high speed rotating grinding plate. The particle size is reduced as it passes through the tapered plates, which has a wider gap at the center of the plates where the materials is introduced and is closest at the periphery of the plate where material exits. The finely ground product exits the grinding zone and discharges into the product container. Essentially the fineness of the product is dictated by the number of teeth on the plates, rotational speed of the rotor, as well as the gap between the plates.
