Abstract
A grinding stone useful for a variety of comminuting applications, but especially useful for comminuting of rubber particles, comprises a cured mixture of a grit material (such as silicon carbide), an aqueous emulsion of an organic polymeric binding material, (such as an epoxy emulsion), a wetting agent, such as DAXAD™, a surfactant commercially available from the Hampshire Corporation of Lexington, Mass., and an inorganic binding material (preferably portland cement). The grinding stones can be prepared at room temperature, using readily available equipment, and at a greatly reduced cost when compared to current grinding stones prepared from silicon carbide and a vitrified ceramic binder. The stones of the present invention may be molded to a metal support plate, resulting in further process efficiencies and reduced stone manufacture and replacement costs.
