Abstract: Grinding body separator in mills for comminuting and crushing deagglomerating solids, predispersed in liquids, which comprises circular rings provided with cross bores. The number of the bores decreases as a function of a decrease in diameter of the rings. The bores are equidistantly distributed on the rings. The diameter or the bores also decrease as a function of a decrease in diameter of the rings.

Abstract: A cooled horizontal-axle grinder for the predispersion of solids in liquids, of the type which incorporates a grinding chamber with a double wall for cooling, in which chamber are presented grinding bodies such as balls generally introduced by the treated product intake port and extracted by an outlet in the lower part of the chamber. The grinder is equipped with a circulating pump for the product to be treated, which product circulates in a continuous manner through the grinding chamber. The grinder axle carries interchangeable discs or agitator elements interspersed with spacers. The grinding chamber incorporates a slot or static sieve which retains the grinding bodies in the chamber while permitting passage only of the product.

The grinding chamber jacket has a helical cooling passage therein which extends axially of the grinding chamber in surrounding relationship thereto.

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.

Abstract: An improved grinding disc, especially devised for mounting on the agitating shaft of a cooled grinder for the predispersion of solids in liquids. The disc has a plurality of apertures therethrough, preferably three in number, which apertures have an inclined outlet edge. When a determined number of discs are mounted on an agitating shaft of a vat with counterpositioned orientation such that the inclinations of the outlet edges of successive discs are directed in opposing directions, opposing currents are created which notably improve the dispersion of solids in liquids.
