【Introduction】:Centrifugal separator is a equipment for gravity separation.
【Capacity】: 0.25~12
【Improvement】: The centrifugal separator creates large centrifugal force through high speed rotating, which strongthen gravity separation process. The micro fineness minerals can be recoveried more efficitively.
Large centrifugal force, lower limitation of recovery fineness
Large capacity and high concentrating rate
Reducing the investment of operation, and reducing the consumption of water and electricity
High degree of automation and easy to operate
The principle of centrifugal separator is that, it rotates in high speed through with a certain convolution through the barrate on it, during this period, the pulp rotates with the barrate. The heavy minerals sink to the inner wall of barrate by centrifugal force and rotates with the barrate. Due to a certain differential velocity, the lighter minerals turn to the discharge end with the barrate as tailings. After the tailings are discharged, the dischaging separator would automatically detach from normal position and prepare to intercept concentrates. Then the washing valve opens automaticly by high pressure. High-pressure flushing water will wash down the concentrates deposited on the inner wall of the barrate. After the concentrates are washed, the high-pressure water valve will automatically close. After the concentrates are drained, the ore distributor and ore feeder will automatically reset and start the next sorting cycle.

After the mineral processing experiments, Xinhai decided to adopt Xinhai three stage jig, four stage shaking table, mud and sand separation based on ore properties. Coarse, medium grain jig tailings were sent to rod mill, and the ground was returned to double vibrating screen, which formed a closed cycle. The shaking table is used in twice separation, coarse grain was returned to the closed cycle, the fine grain was returned the original work. Slime individual treatment, including coarse level table recovery, fine to original process. The pulp need to be handled separately, and shaking table recycling was adopted in the coarse grain, Xinhai centrifugal separator recycling was adopted in the fine grain, ultimately the whole process obtained jigging rough concentrate, shaking table rough concentrate and fine mud rough concentrate.
