gravity mineral processing machinery is a kind of equipment that uses the difference of density and particle size between ore particles and gangue to separate in moving medium, including jig, heavy medium concentrator and centrifugal concentrator. Jigging machine makes water flow in water tank by means of diaphragm, piston or compressed air, so that the ore particles on the screen are stratified according to density and particle size under the action of pulsating water flow.

Centrifugal concentrator is a machine used to recover metal particles in fine slime, which is mainly composed of host and control mechanism. In the centrifugal force field proced by the high-speed rotation of the cone drum of the main engine, the heavy ore particles deposit on the drum wall and become the concentrate, while the light ore particles attach to the surface of the concentrate and are discharged from the drum and become the tailings under the action of the flow film (pulp flow)
