Shredding process and plant

摘要

The invention relates to the field of very fine comminution of solid materials, which can be different and have different strength properties. In a new comminution device, a mechanical comminution process in which a millbase in the form of a gas-solid suspension is divided into streams in their circumferentially closed channels between shredding elements on oppositely rotating rotors are guided against the annularly arranged rotating shredding elements of an oppositely rotating rotor, combined with a generally directly following aerodynamic method, in that a collision of the material flows from the channels in an annular gap between the Rotors is brought about with swirling. The comminution is preferably carried out in addition in an outer ring area between the edge of the rotors and the housing wall, in which additional impact plates are arranged, before the product is discharged.
