Spiral Chute

Information of Spiral Chute

The spiral chute is a new type of domestic equipment developed in 1977, which integrates the advantages of spiral concentrator, shaking table and centrifugal concentrator. Spiral chute is suitable for separation of 0.3- 0.02 mm fine materials. The equipment is stable, easy controllability and has a wide range of permissible concentration. It has the advantages of high enrichment ratio, high recovery rate, small area, low water consumption, simple structure, no power, large handling capacity, simple installation, easy operation, small investment, and quick effect.

Structure Features of Spiral Chute

• Glass-reinforced plastic spiral chute dressing is composed of glass-reinforced plastic spiral blades. According to different processing capacity, the screw set can be made into different layers, that is, single head, double head, three head and four head structure.
• The cross section of the spiral chute is a cubic parabola, which can improve its performance. The variation of curve operation is especially suitable for the selection of fine grain materials.
• The spiral chute is simple in structure and usage, which also has anti-corrosion function. In use, it is not easy to be corroded by minerals. The equipment also has the advantage of strong adaptability, which can adjust the fluctuation of mineral quantity and concentration.
• The spiral chute of FRP has strong practicability, which can realize a large number of ore separation at one time. Its work efficiency is high, and  can adapt to different requirements of environment. In use, it will not produce any noise, nor any power can achieve normal operation. FRP spiral chute can not only be used in mineral processing industry and mining industry, but also in sand mining industry such as riverside and seashore.

Working Principle of Spiral Chute

Raising the spiral chute, calibrating the vertical line, and fix it in the proper position with iron frame or wood. Sand pump will be sent to the top of the screw two feed mouth, adding appropriate amount of water, adjusting the concentration of mine paddle. Mine pulp flow from high to low, creating a centrifugal force of inertia in the velocity of rotation. The separation of ore and sand can be achieved through the effect of gravity and centrifugal force of the cyclone, and the difference in the specific gravity, particle size and shape of ore and sand. The concentrate flows into the concentrate bucket with the pipe to take out, the tailings flow into the tailings bucket with the pipe to connect to the sand pool, and then with the sand pump to drain away, complete the whole process of dressing.

The Working Principle of spiral chute

The Key Points of Spiral Chute

• The direction of spiral chute leaves must be consistent with the movement direction of pulp;
• The final interception of concentrate, middling and tailings;
• Uniform feeding, the 30%--35% concentration is the best;
• When the feeding stops, the residual on the helical blade must be cleaned.
