Disintegrator for fine-grade milling of pure starting materials

摘要

The design of a disintegrator for fine-grade milling with a low degree of contamination due to wear. The disintegrator has rotor discs which rotate in opposite directions and have, on the one hand, bearing pins which are inserted into holding rings and consist of a metallic core, and trough-forming walls which receive between them on the impact side a cushion of material for milling consisting of milled material and unmilled starting materials. The trough-forming walls are constructed from the starting materials and/or from the milled material.
