  • Patent number: 5011089
    Abstract: In a dispersing process, a mill base consisting of solids and of a liquid phase is conveyed through a stirred ball mill containing a grinding medium, energy being supplied in this stirred ball by rotating rotors to disperse the solids are dispersed, wet with the liquid phase. The rotors rotate at such a high speed that the grinding medium moved by them forms, as the result of the centrifugal force, a rotating grinding medium charge which is in contact with the inner wall of the stirred ball mill, a space which is essentially free of a grinding medium being formed in the center of this grinding medium charge. The mill base is fed radially into the stirred ball mill and flows radially through the grinding medium charge in such a way that a centrifugal fluidized bed is formed with respect to the grinding medium. The mill base is removed from the space which is free of grinding medium through an apparatus such as a sieve for separating off grinding medium.
