ABSTRACT:
A cooled horizontal-axle grinder for the predispersion of solids in liquids, which grinder incorporates a grinding chamber having grinding bodies such as balls therein. The grinder has a circulating pump for the product to be treated which circulates in a continuous manner through the grinding chamber. The rotatable grinder axle carries discs or agitator elements. The grinder includes a separating sieve designed to retain the grinding balls within the grinding chamber while permitting the finely ground product to flow into the interior thereof and then along and around the axle. The sieve includes a cylinder coaxial and rotatable with the axle and having slots of suitable shape to realize the aforementioned function. The cylinder has product outlet holes which communicate with a surrounding cylindrical product chamber. A separator structure surrounds this rotatable cylinder and coacts with a housing wall for defining a narrow flow passage which communicates directly between the grinding and product chambers. The passage is sized similar to the slots in the sieve.
