Abstract
Waste disposal mechanisms, particularly a glass grinding machine for disposal of glass bottles or the like. The glass bottles are advanced through an inclined feeding chute onto a rotor having transverse blades which shatter the glass into fragments, and urge the glass fragments through a lower, arcuate grinding grate. Glass particles retrieved beneath the arcuate grinding grate may be used as building material or transported in their comminuted form to landfills at greatly reduced savings in bulk and handling.
Claims2
A glass grinding machine comprising:
- a) a housing, including an upper glass feeding section, a grinding chamber and a lower grate section, together with an inclined glass feeding chute supported in said housing upper glass feeding section above said grinding chamber;
- b) a grinding rotor, rotatably supported within said housing grinding chamber, by means of a transverse axis extending through the grinding chamber into bearing supports at each end, said grinding rotor having a plurality of radially extending grinding blades;
- c) a grinding grate supported within said housing grate section beneath and apart from said grinding rotor, said grinding grate including a plurality of spaced apart blades disposed in arcuate and complemental array with respect to said rotor radially extending grinding blades configured so as to define an oblique grinding surface with respect to the periphery of said rotor being approximately 45.degree. with respect to the periphery of said rotor, and said blades being spaced apart approximately 1/8", said grinding grate further including an outlet funnel extending downwardly and away from said grinding grate together with a glass particle receiving container supported beneath said outlet funnel;
- d) a rotor drive operably connected to said rotor, so as to rotate said rotor at such speed as to break glassware upon contact with said rotor and urge broken glass through said grinding gate, and
- e) a glass container holding tray affixed to the exterior of said housing adjacent said inclined glass feeding chute.
