<p>A method for processing scrap glass to produce uncontaminated glass particulates having rounded edges. In a preferred embodiment, the method comprises introducing the glass into a circular grinding chamber (14) and rotating a driver (30) within the grinding chamber at a curvilinear velocity of about 10 meters per second. The driver is configured to urge the glass to roll around the grinding chamber, thereby rounding any sharp edges of the scrap glass without the use of grinding compounds. The uncontaminated glass particulates having rounded edges which have been ground without the use of grinding compounds may be used as a substitute for natural sand. Such uses include for decorative purposes, for sports turf applications including golf course sand bunkers and top dressing for greens, as a soil container, as a filtering media, and as filler sand for down hole fracturing in oil wells.</p> |
