Quartz silica sand is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white or colorless and translucent, with a hardness of 7, which is brittle and has no cleavage.
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.
