picocross pin mill

The picocross is a 2-rotor contra-rotating impact mill designed for the dry milling of soft to medium-hard materials. The mill is created by equipping the picoplex with a second driven pin disc. The design and principle of operation are largely identical with that of Alpine's  Contraplex impact mill C product line.

The contra-rotating pin mill with 2 driven pin discs. It produces high powder fineness values in the range 10 µm — 500 µm.

  • Operating principle

    The feed material is dosed into the centre of two contra-rotating pin discs and is comminuted by impacting against the grinding pins. The high shear speed of the contra-rotating discs permits a particularly intensive stressing of the particles.

    After being processed in the grinding zone, the product moves into the mill housing before exiting the mill by gravity. The rotation generates an air flow from which the product is extracted in a filter. The fineness of the end product is set by varying the speed of the two rotors and the feed rate.
