ABSTRACT:
A method for the production of spherical granulated materials from powdered solids and the granulated materials produced by it are disclosed. The method is characterized in that the powdered solids are moistened, possibly together with the usual binders, flow agents and plasticizers for the compression of solids, by the addition of a corresponding quantity of liquid and mixing smoothly in a mixer; they are then compressed with a ring collar mill into cylindrical agglomerate and then rounded in a rounding unit with wrinkle washer. The granulated solids thus produced have a very narrow particle size distribution and are distinguished by good flowability and good dispersability, depending on process controls.
