Consists of a cylindrical shape metal cup. There are various steel discs on the rotating mill along the axis of the cup. Hard beads of 0,5-3,0 mm diameter are placed in the mill together with the pigment paste to be grinded. The pigment agglomerates between the moving beads are grinded with the help of the friction between the beads that are moving with the whirling effect of rotating discs. Until recently, similar mills containing high silica sand instead of beads were widely used. These mills were called sand mills.
