Information of Spiral Chute

Spiral gravity separator spiral chute is also called spiral concentrator or gravity separator, it’s a kind of gravity concentrator which can separate mineral particles according to density, granularity and shape by the interaction of centrifugal force, friction force of chute surface, water flow pressure and gravity of minerals. Spirals are made of high-density fiberglass, high quality emery and unsaturated resin. 

Working Principle Of spiral chute

Erect the spiral chute, calibrate the perpendicular line and fix it in a proper position with iron structure or wood. Send the mineral sand with the sand pump to the two feeding mouth on the top of the spiral chute, add make-up water to adjust the density if the ore pulp, and the ore pulp will naturally rotationally flow down and produce an inertial centrifugal force in the rotary slant flow. The gravity and the centrifugal force will separate the ores and sand according to the proportion, granularity and the shape of the ore sand, and the ore concentrate will flow into the concentrate funnel and be discharged with the pipe and tailings will flow to the tailing funnel and be discharged to the sand tank with the pipe and drained by the sand pump to complete the whole separation process.

Advantages Of Spiral chute

• Reasonable structure and small occupation area.
• High recovery, high efficiency, and precise separation.
• Low operating cost and long working life.
• Reliable running with minimal operator attention.
• Strong adaptability to fluctuation of feeding amount, density, size and grade.
• The surface of corundum forms strong friction the concentration effect surpass plastic surface.

Spiral chute structure

The Spiral Separator consists of a spiral separation channel, an inlet, and a drive unit, which utilises the differences in the physical properties of the different components through the movement of the material in the spiral channel to achieve separation.
