An apparatus and method for forming superfine particles of rubber powder suitable for recycling, as by incorporation into new rubber production, is shown. Coarsely ground rubber particles, formed in a conventional manner, are mixed in a soaking vessel with a reagent which causes the rubber particles to swell. The swollen, reagent-impregnated rubber is less elastic and more easily ground. The reagent-impregnated particles are then transported to a grinder which reduces the size of the particles to 200 mum or less. The ground particles are then heated to drive off the reagent which is recovered in a reagent recovery system. The dried particles are then sorted according to size. The process is conveniently automated and provides the ability to economically recycle rubber.
