Review of the working bodies of vertical bead mills

Abstract

It is considered existing configurations of the working members of vertical bead mills for grinding cosmetic, pharmaceutical and food products by a wet method. In standard designs of rotors with disks and / or pins, due to the presence of centrifugal forces, there is a stagnant zone in which the movement of the beads and the product is practically not observed. As a result of which the product has an uneven particle size distribution and the time spent on the process increases. the configuration of the rotor with a reduced annular gap provides a reduction in the time of grinding of solid materials in suspension, with a smaller volume of the grinding chamber.
