Several Concentrators Used in Ore Dressing Production

In the mineral processing production, ore particle precipitated out from pulp is required to be dehydrated, which is accompanied by dehydration equipment such as concentrator. Commonly used concentrators used in ore dressing production are as follows.

(1) Center drive type concentrator

Center drive style concentrator is often with medium and small scale. When industrial sites are nervous and adequate settling area is requested, in order to reduce footprint, save energy and reduce infrastructure costs, center drive multilayer concentrator is required.

(2) Peripheral transmission type concentrator

Peripheral transmission type concentrator is always in large scale. Advantages of peripheral drive thickening machine are: simple equipment, convenient operation and maintenance, small power consumption and so on. Its main drawback is that covers larger area and low processing power.

(3) Inclined plate thicker

Inclined plate thicker is a new type high efficiency concentrator, with shape of square box and a pyramid under the funnel. The pulp is fed into the gap between two sloping plate along the full width of the box, then flowed up through the upper tilting plate clearance. In the process, particles will be settled and precipitated, so the upper tilting plate is called enrichment. The solid particles settling down on the surface will slip drop down in the lower plate to void continue settlement. Grit will be discharged at the end of the cone-shaped funnel, and the sand excretion and concentrations can be controlled by exhaust valves with different diameters.

Inclined plate thicker is commonly used for dehydration, desliming and concentration of fine mine in the process and other operations. Most important feature of inclined plate thicker is simple structure and concentration effect. Discharge opening is easily to be blocked, so inclined plate thicker should not be used in operations required high product concentration.
