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.

Knelson centrifugal concentrator is an efficient gravity separation equipment, which can reduce the lower limit of the particle size of the target minerals and increase the recovery rate of gravity separation,often used for gold separation.Since the feeding particle size of the knelson concentrator must be less than 6mm, it is necessary …

Back. Knelson concentrator mainly has the following 6 characteristics: High concentration ratio, usually 1000-3000 times. Concentrate grade is higher, generally 1000-2000g /t. The recovery rate is significantly higher than that of conventional gravity separation equipment. Large processing capacity. The processing capacity of KC-XD70 and KC ...

On each figure the results obtained with the Knelson and the Falcon are presented. It clearly appears that the Falcon achieves recoveries very close to in the full range of CP. With Knelson, the recovery is for the 45-250 microns tungsten at low CP values and drops dramatically when CP is increased.

Knelson Concentrators is a centrifugal reselection equipment developed and produced by Canada Knelson Reselection Solutions Company. As early as 1978, the product began to be commercially used. After continuous development and improvement, it has now formed two categories of intermittent and continuous types.

The key difference between the two types of centrifuges is that the bowl angle of the Knelson ™ concentrator is shallower than the angle of the dynamic slurry face while the bowl angle of the Falcon concentrator is steeper. The overall bowl angle of the Knelson ™ concentrator is approximately 13 degrees from vertical.

The first Knelson Concentrator was trialled in 1976, 40 years ago, and Knelsons have been at the forefront of the industry ever since. Through all those years, Knelson has been widely accepted as the gold standard of gravity recovery. Not long after the first Knelson was unveiled, other companies and would-be manufacturers picked up on the idea ...

Abstract. The Knelson concentrator (KC) is widely used in gold ore and other precious metal ore processing technology because of its excellent separation performance. The development history and types of KCs are reviewed in this paper. Research on the separation mechanism and characteristics of KCs was analyzed and discussed, …

Knelson Concentrators adopted and used these procedures to develop their KC-MOD*Pro circuit simulator, which allows accurate modelling of plant recovery on the basis of lab test results. GRG, EGRG and modelling now allow fully informed decisions about gravity processing to be made long before the casting of first concrete on a new plant.

GCA has successfully commissioned two KC-QS48/ICS FL Knelson Concentrators at Asanko Gold 's project in Ghana. The KC-QS48s at Asanko are each rated at 400 tph solids (40-70% solids in feed pulp). The plant design was a fairly 'standard' and well-proven design, which incorporated a coarse crusher, SAG mill, and a Knelson concentrator.
