Progressive grinding as a result of the grinding gap tapering towards the periphery The tooth geometry of the one-part grinding disc is dictated by the problem specification to permit reaching optimum results and simultaneously to minimise maintenance and wear End-product fineness ranges from several hundred µm to 2 mm High throughput at low specific energy consumption Temperature and filling level measurement in grinding chamber ensures a constantly high product quality PRINCIPLE OF OPERATION The feed material, usually between 4 and 8 mm in size, is fed into the grinding zone via the intake chute on the mill door. Size reduction takes place between the axially adjustable stator disc and the rotating grinding disc, which rotates at a high peripheral speed in accordance with the shearing and cutting principle. The actual grinding is effected in stages through a grinding gap which tapers from the inside to the outside. The finely ground product exits the grinding zone through an exactly defined gap. Wherever an exact top-size limitation is required, the mill can be operated in circuit with a suitably designed screening machine. The oversize particles are routed back into the grinding zone. Most types of plastic can be finely ground at ambient temperature using this technology. If, on the other hand, the feed material is heat-sensitive, cryogenic mode is also possible.
