Abstract:
A free-abrasive machining slurry recycle system for processing used slurry into makeup slurry of constant average particle size comprising:a pre-separator section where said used slurry from a free-abrasive machine tool is received and conditioned for further processing,a separator wherein said used slurry is reduced into an abrasive-rich component of slurry and a kerf-rich component of slurry, said abrasive-rich component containing relatively larger heavier particles and said kerf-rich component containing relatively smaller lighter particles,means for monitoring particle concentration of at least one said component of slurry,means for adjusting a separating force and dwell time of said separator in response to changes in said particle concentration,means for adding additional abrasive or carrier to said abrasive-rich component as required in response to said changes in particle concentration, said makeup slurry comprising the result to said abrasive-rich component of said means for adjusting and said means for adding,means for dispensing said makeup slurry to said free-abrasive machine tool, andmeans for removing said kerf-rich component from said system.
