Product Overview

The water jacket centrifugal concentrator (Nelson centrifuge) is a high-efficiency core gravity separation equipment specially designed for the enrichment of gold and heavy minerals. It adopts the high-speed centrifugal sedimentation principle combined with a wear-resistant water jacket structure, focusing on the high-efficiency recovery of placer gold, vein gold and fine gold, and can also be used for the separation of tungsten, tin and other heavy non-ferrous metal minerals. The equipment strengthens the sedimentation of heavy minerals through centrifugal force and forms a stable separation environment with the water jacket to achieve accurate enrichment of gold particles. It is suitable for large-scale dressing plants, placer gold mining and tailings recovery scenarios, with the advantages of high recovery rate, large processing capacity and convenient maintenance.
