  • Method and apparatus for recycling slurry
    Patent number: 7059943
    Abstract: A slurry recycling apparatus having a first filter, a dirty side storage tank, slurry pump, second filter, clean side storage tank and slurry outlet, in which used slurry from an edge notch polishing apparatus is delivered to the first screen filter, transported to the dirty side slurry storage tank, pumped from the dirty side slurry storage tank through a second filter that filters out small particulate matter from the slurry and allows the slurry to pass to the clean side slurry storage tank, and finally to the edge notch polishing apparatus as needed. Slurry which is not immediately taken from the clean side slurry storage tank is continuously recycled through the second filter by overflowing from the clean side to the dirty side slurry storage tank where it is there pumped through the second filter back into the clean side slurry storage tank.
