Abstract (en)
[origin: WO9633019A1] The invention concerns a method and a device for wet-grinding and dispersing solid particles in liquids, using a stirrer-type grinder consisting of at least one chamber (1) containing grinding elements (3) and at least one rotor (2), the chamber (1) and rotor (2) being designed to be rotated independently of each other by at least one drive (8, 8') and the material to be ground (4) being fed into the grinding chamber (1) through a hollow shaft (5). The grinding elements (3) in the grinding chamber are strongly compressed by the rotation of the chamber. The rotor (2) is set in motion, the rotational speeds of the chamber (1) and the rotor (2) keeping in step with each other, the rotor (2) turning at a constant faster speed or constant slower speed than the chamber (1), or at alternating faster and slower speeds, or at the same speed. The material is fed into the chamber (1) containing the rotor (2) through a hollow shaft (5) and, after grinding, is thrown by centrifugal force through outlet openings (11) into a collector container (14).
