Glass Pulverizer Systems

Our glass recycling systems also produce a distinctly different product: A rounded glass particle, 3/8″ in size or finer. If material other than glass (plastic, metal caps, or covers) goes through the pulverizer, these materials will keep their larger form and thus be easily separated from the glass-sand within the trommel separator.
