Decanter Centrifuges for Solids/Liquids Separation in Minerals Processing and Tailings Applications

Centrifugation in mineral processing is achieved by using Shenzhou industrial centrifuge decanters, also known as centrifugal decanters. These specialised centrifuge decanters reduce waste and increase overall & separation efficiency.

Manufactured by the world-renowned centrifuge specialists Shenzhou has successfully supplied and installed centrifugal decanters to mineral, chemical and industrial processing international markets for more than 4 decades.

Ideal for all mechanical solid / liquid separation, centrifugation in mineral processing achieves thorough separation by dewatering large quantities of solids to realise low final moistures. When using Shenzhou-supplied equipment for centrifugation in mineral processing, the cost of thermal drying is considerably reduced. This, when combined with the fact that Shenzhou’s machine process knowledge helps optimise customers separation applications, becomes a distinct advantage. 

Benefits of Centrifugation in Mineral Processing: 

Reduced thermal drying and other processing costs

Increased separation efficiency for particles of all sizes

Compact design facilitates use in small operating areas

Reduces waste with optimised separation

Centrifugal Decanters from Shenzhou Centrifugal decanters from Shenzhou operate on the counter-flow principle. Suspension is introduced to the centre of the bowl for separation. Sediment is then conveyed via the scroll, which continuously rotates at an altered speed to that of the bowl, resulting in clarified liquid flowing from the bowl’s large diameter opening. Optimum control of the required separation process is achieved by continuously adjusting the height of the bowl’s liquid level and the resulting ratio of clear liquid and dry solids. A well-proven gear unit is used to obtain the differential speed between the scroll and the bowl, using V-belts as the standard drive arrangement. However, depending on the required rotating speed combination, the centrifugal decanter is equipped with a single drive or double drive design.

Centrifugal Decanters from Shenzhou are available in 3 distinct, application-specific types and come with international service and support:

TS Decanter Centrifuge:  used typically in gas-tight process systems

High degree of reliability

Closed process housing

Proven sealing design

DZ Decanter Centrifuge: supplied in an open process, vapour-tight and gas-tight design

2-piece product housing sealed with chamber rings

Rotating part geometry designed specifically for separation equipment

Machines with bowl diameters > 1 000 mm are standard
