Method and device for micronising adhering materials by means of directed eddies

摘要

In the method, the material for crushing is input into an input crushing chamber (8) and crushed therein. Microeddies are applied to the particles produced by a main eddy, the comminution taking place at the boundary areas between the main eddy and the microeddies at the circumference of the input crushing chamber. Subsequently, the material for crushing is fed to at least one further crushing chamber (9). The method is realised by a device which is constructed as a crushing system with at least one rotor (12) with blades (2) and with channels (5) which themselves are located at a fixed angle with respect to the radius of the rotor, the rotor (12) being mounted on a shaft (11). The individual crushing chambers (8, 9) which are located on both sides of the rotor (21) are closed off with covers (3, 6), the cylindrical stator (1) with axial channels (10) being common for all the crushing chambers (8, 9) and an opening (4) for the material for crushing and the gas stream being provided at the front cover (3). <IMAGE>
