Home -> Mineral Processing Equipment -> Centrifugal Concentrators

The semi-continuous (batch) Knelson Concentrator is the most widely utilized centrifugal gravity concentrator for gravity recovery in the mineral processing industry.

Knelson Concentrator unit capacities ranging from laboratory scale to 1000 tonnes of solids per hour, and combines centrifugally enhanced gravitational forces with a patented bed fluidization process to provide unmatched performance in the recovery of precious metals.

Rugged design and a high degree of quality manufacturing ensures that every Knelson Concentrator will provide many years of reliable, trouble-free operation in even the most severe operating environments.

The semi-continuous Knelson Concentrator has been successfully applied in the recovery of gold, platinum, silver, mercury and native copper.

The semi-continuous Knelson Concentrator is available in three models; Extended Duty (XD), Centre Discharge (CD), and Manual Discharge (MD).

Series
Extended Duty (KC-XD) Knelson Concentrators

The Knelson Extended Duty series (KC-XD) is the premium class of semi-continuous (batch) centrifugal concentrators available in the mining industry today.

The XD was specifically designed to withstand the severe operating conditions inherent to hard-rock milling circuit. Compact design, rugged construction and the highest possible level of quality components makes KC-XD the unit of choice for the most demanding precious metal recovery applications.

Centre Discharge (KC-CD) Knelson Concentrators

Until the introduction of the XD series, the Knelson Centre Discharge series (KC-CD) was the industry workhorse and most widely used centrifugal equipment for precious metal recovery. The Knelson KC-CD concentrator has now become the machine of choice for most alluvial mining operators where conditions are generally less severe than those present in hard rock mill environments. The Knelson CD series is also an economical alternative for applications where project economics may not support the purchase of a premium class KC-XD unit. While the CD series provides a cost effective alternative to the XD series concentrator through the use of carbon steel construction, it still provides precisely the same high level of metallurgical performance as the XD model line of centrifugal concentrators.

Laboratory & Testwork Knelson Concentraotrs

Knelson offers laboratory and pilot-scale concentrators for bench-scale testwork, in-plant sampling and for in-field alluvial exploration projects.

Lab and pilot-scale Knelson Concentrators has become the standard in all state-of-the-art metallurgical laboratories around the world. Ranging in throughput size, the KC-MD3, KC-MD4.5 and KC-MD7.5 are built with the same strict quality standards as the larger throughput capacity Knelson Concentrators.
