A cooled horizontal-axle grinder for the predispersion of solids in liquids, which grinder 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 circulates in a continuous manner through the grinding chamber. The rotatable grinder axle carries interchangeable discs or agitator elements interspersed with spacers. The grinder includes a separating sieve designed to retain the grinding balls within the grinding chamber while permitting the finely ground product to flow therethrough to the exterior along the length of and around the axle. The sieve includes a cylinder coaxial with the axle and having slots of suitable shape to realize the aforementioned function, which cylinder is coaxially coupled to a cylindrical chamber with product outlet holes so that the sieve cylinder rotates jointly with the grinding chamber axle and, due to this, produces a displacement of the balls towards the exterior by reason of centrifugal force.
