Apparatus for comminuting, crushing and disagglomeration of solids dispersed in liquids

In a mill having an outlet and a grinding body separator, comprising a stator and rotor with a grinding chamber therebetween, and having a longitudinal axis and a truncated cone-shaped stepped support for grinding and breaking up solids predisposed in a liquid, the improvement comprising a separator 1 having a fixed base support 25 in the form of a truncated stepped cone fixed to the stator and supporting a plurality of rings 26 positioned on a series of circular steps formed on said base support 25;

• said circular steps and said rings being parallel to each other and perpendicular to the longitudinal axis of said separator;
• and said rings being of decreasing diameter from the base support to its cone end;
• each of said rings having a plurality of through bores wherein the number of said through bores decreasing as a function of a decrease in the diameter of said rings, and wherein said through bores are equidistantly spaced about said rings and enable the flow of said ground solids to enter and traverse said rings of said separator and to exit therefrom uniformly and smoothly and without any accumulation of solids in the grinding chamber of the mill.
