Material Removal Rate - an overview ScienceDirect Topics

In HEDG, a possible removal rate as high as Q = 1200 mm 3 /s over a grinding width of 2 mm translates to Q′ = 600 mm 2 /s (or 55.8 in. 2 /min). Such high removal rates create high stresses on the grinding wheel grains and require appropriate grinding wheel design to avoid rapid wear. The HEDG operation removes material 300 times faster.

HPGR High Pressure Grinding Rolls

Hydrocyclone Feed Pump Pressure PSI vs Operating Parameters

For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation. First the pump pumps all of the slurry out of ...
