Abstract
Granular molding materials for fabricating abrasive articles, such as, for example, grinding wheels, are produced by mixing heated abrasive grains with a resin blend including two phenol-novolac resins. Preferably, the resin blend is added to the abrasive grains in the mixer apparatus of the invention, which can be a bowl type mixer. The mixer can be preheated by directing a heated gas, such as air, across the mixer. The granular molding material can also include a curing agent, fillers and other materials generally employed in fabricating abrasive articles.
