Attrition Milling System
The Attrition Milling Systems are high-speed cutting mills designed for the fine size reduction of plastics, polymers and fibrous materials that do not respond well to other forms of impact milling. They are designed to grind heat sensitive and soft materials without liquid nitrogen or conditioned air.
The feed 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 shearing 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 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. These systems are capable of fine grinding to D90 = 100 µm or finer depending on the material and application.
