Flotation Machine

Flotation machine has different types; there are mechanical agitation type, inflatable, hybrid, and air mixing and gas evolution type flotation machines. It is mainly used for separating non-ferrous metals such as copper, zinc, lead, nickel and gold but also used in the roughing and selection of black metal and nonmetal materials.
Working Principle
When flotation separator machine works, the motor belts drive impeller rotate and it generates centrifugal effect and negative pressure. On the one hand, the sufficient air mixes with pulp; on the other hand, mixing slurry mixes with drugs and meantime refines the bubble. Then the mineral adhesive foam floats to the pulp surface and then forms the mineralized froth. By adjusting the height of damper and controlling the liquid level, the useful foam is scraped by scraper.


1. The impeller has backward double blades which can realize groove pulp dually cycles.

2. As China flotation manufacturer, Xinyu flotation separator machine is of big inspiratory capacity and forward type tub with less dead angle and high bubble moving speed.
3. The impeller rotational speed is low. And the impeller cover plate has long service life. Pulp cycles dually according to fixed way which is conductive to the recovery of coarse-grained minerals in suspension.
4. Lead and zinc ore flotation machine is of simple operating and highly automaticity.
