Processing Materials
Gold, silver, platinum group, tin, tungsten, lead, tantalum, chromium, titanium, hematite and other ores.
Application scope
The beneficiation centrifuge is suitable for the recovery of precious metals, including gold, silver, platinum group, tungsten, cassiterite, tantalite, chromite, hematite and other minerals with high specific gravity. The most widely used ones are the recovery of rock (vein) gold, sand gold and associated gold of non-ferrous metals.
Advantages and characteristics

1. The beneficiation enrichment ratio is high, the concentrate yield is low, the grade is high, and the recovery rate is significantly improved compared to conventional gravity separation equipment.
2. Large processing capacity, high operating efficiency, capable of continuous ore feeding and discharging.
3. High degree of automation, easy operation and management, low power consumption, low daily maintenance of equipment, and low production costs.
4. Small footprint, easy to integrate into the configuration of existing mineral processing production lines.
product mix
A beneficiation centrifuge is composed of feeding pipes, frames, tailings tanks, motors, transmission bearings, and beneficiation components.
The ore dressing components are divided into two layers: the inner layer is a conical body with a head, and the inner layer is made of stainless steel with a circular grid. There are many small holes on the cone wall. The outer layer is made of ordinary steel plate and forms a closed water jacket with the inner layer. When the selected ore centrifuge is running, the centrifugal acceleration inside the enrichment cone can reach 60 times or higher than the gravitational acceleration. When the slurry is fed into the bottom of the enrichment cone, it is thrown towards the inner wall of the enrichment cone under the action of centrifugal force and moves upward along the inner wall. At the same time, water flow is continuously injected into the cone through the inlet hole of the enrichment cone to make the bed fluidized.
Under the combined action of centrifugal force and recoil hydraulic force, single heavy mineral particles such as gold can overcome the radial resistance of water and settle in the concentrate bed by centrifugal or drilling clearance. However, due to the small centrifugal force, gangue minerals are difficult to overcome the effect of hydraulic recoil. As a result, they are discharged from the enrichment cone and become tailings under the combined axial force of water flow and centrifugal force.
