Abstract
Grinder has a motor driving a set or rotary grinding knives and a fan placed in the housing so as to create an air flow assisting the introduction of the plastic material and its passage to the grinder. The grinding device pref. consists of a turbine, and a screen may be interposed between the knives and the turbine to reject oversize particles. The grinder gives a good yield with scrap material.
