Hydrocyclone Working Principle - 911 Metallurgist

Aug 06, 2015  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 inside the cyclone. The centrifugal force ( the central Hydrocyclone Working Principle ) that is generated by this spin, forces the “bigger particles outwards towards the wall of the cyclone.

Cyclonic separation - Wikipedia

Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of ...
