Cyclone canisters enable hydrocyclones to be efficiently grouped together to allow high feed volumes through small diameter hydrocyclones and maximise the number of fine particles separated within the feed material. This can reduce the size of the water treatment plant or the water clean up required on site.

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 …
