The work of the knelson gold centrifugal concentrator is intermittent, so after a period of ore feeding, it is controlled by the control mechanism to stop feeding ore and open the flush valve to flush the concentrate deposited on the drum wall out of the machine. After the concentrate is rinsed, close the rinse water valve and start feeding the ore again. This cycle goes back and forth. The whole process is controlled by the control mechanism and is carried out automatically.

The ore feeding method of the gold centrifugal concentrator is to feed the ore from the upper and lower duckbill-shaped feeding nozzles. The direction of the ore pulp ejecting from the ore feeding nozzle should be tangential to the drum, so that the ore pulp is fed into the drum wall. certain tangential velocity. The disadvantage of the duckbill-shaped feeder is that it is easy to block and the tangential flow of the feed is too fast. Another ore feeding method is open ore feeding, which can avoid blockage and also avoid the disadvantage of too fast ore flow during duckbill feeding.
