Universal Cutting Mill USM: High precision for the fine cut

The Universal Cutting Mill USM granulates precisely and quickly material already pre-shredded.

The results are defined, pure-grade granule sizes of secondary raw materials, which can be used for the production of new products. The Universal Cutting Mill USM is especially suitable for the fine granulation for the recycling of used tires, plastics and cables and is mostly used as the final shredding step in a complete process. The machine shreds the material to 0-4 mm and thus breaks up the last remaining material composites. The individual fractions can e.g. subsequently be separated with a non-ferrous separator. The individual fractions like copper, aluminum and plastics are then available in a high purity and quality.

The ANDRITZ MeWa Universal Cutting Mill USM is the last shredding step in the recycling process for perfect fine granulation.

Operational principle

Similar to the operational principle of the Universal Granulator UG, the fine granulation in the Universal Cutting Mill USM is carried out with the shearing effect of rotor and stator knives. The “double helical cutting geometry” enables a precise cutting gap over the complete working width of the machine and ensures at the same time a power favorable cut. The granulation screen mounted underneath determines with variable hole sizes of 0-4 mm the granulation as well as the respective throughput.  Underneath the screen a collection tray is placed, from which the granules are pneumatically sucked off or transported with a discharge screw conveyor.
