A method and device for the comminution of schuettfoermigen materials

摘要

a method and a device are proposed for the grinding of schu00fcttfu00f6rmigen materials. the zerkleinernde material from above a first beschleunigereinrichtung into these in a first materialschu00fcttung, with fine zerkleinerungsprodukte from this first zerkleinerungsvorgang by an air or gas flow to be delivered.groberes grain pours down and through a vertically upward air or gas flow to further beschleunigereinrichtung into the material in a more materialschu00fcttung brings.the fine-grained zerkleinerungsprodukte achieved here by air or gas flow up route, while the large grain herabrieselt and again in the circuit is introduced. the invention relates to the combination of a vertikalprallmu00fchle with a viewer, both of which are preferably within the same housing are arranged.
