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.
