Explain The Ore Processing Operation
Hydrocyclone Working Principle
Due to the ore being pumped, the slurry has VELOCITY. It is this velocity and point of entry helps in creating a spiral path around the outside of the body, the upper and the lower cone. The entrance to the cyclone was designed this way to allow the incoming feed to help generate and not interfere with the spiral path that the ore must take ...
