The water jacket centrifuge is composed of feeding slot, frame, tailing slot, concentrate slot, double-layer centrifugal tank, driving motor, bearing chamber, vertical shaft and other components. The double-layer centrifugal tank is divided into inner and outer layers. The inner layer is a cone-shaped body like a washing machine dryer. It is welded with stainless steel and has annular spacer bars. There are many small holes on the inner cone wall. The outer layer is also a cone-shaped body and forms a closed water jacket with the inner layer. The middle transmission shaft is a hollow shaft, and the pressure water is flushed into the inner sleeve of the double-layer centrifugal barrel through the hollow shaft, and is sprayed into the spacer bar through the inner hole to form the backwash water. Under the action of high-speed centrifugal force, the pulp slides upward along the inner cone grid, heavy substances such as heavy monomer gold precipitate between the strips, and light substances slide upward until they reach the upper opening of the double-layer centrifugal bucket and are discharged through the tailing tank, The heavier material is deposited at the bottom of the spacer, and the lighter material is continuously replaced by the new heavy material. After a period of time, the gold bearing heavy material is cleaned out between the spacer.

Application: Nielsen centrifuge is suitable for the recovery of precious metals, including gold, silver, platinum group, tungsten, cassiterite, tantalite, chromite, rutile and other large proportion minerals enrichment, among which the most widely used is the recovery of rock (vein) gold, placer gold and non-ferrous metal associated gold.
Applied Materials: gold, silver, platinum group, tin, tungsten, lead, tantalum, chromium, titanium, hematite and other ores.

Equipment advantages:
1. Compared with other products, the equipment has high gravity separation efficiency, which can screen out metal minerals more finely, and has higher recovery efficiency of raw materials.
2. The equipment has high degree of automation, fast operation efficiency, simple operation and low failure rate, which greatly reduces the labor cost.
3. It can deal with raw materials in large quantities and select metal minerals efficiently.
It has low requirements for environment and site, and is easy to match, which can be quickly integrated into the existing production configuration.
