Spiral chute
A gravity separation equipment that uses the inertial centrifugal force generated by the slurry in the spiral rotation motion to achieve the separation of light and heavy minerals.
Stable, easy to control, and wide concentration range.
Large material processing capacity, high enrichment ratio, and high recovery rate.
Small space occupation, low water consumption, simple structure, and no power required.
Simple installation, convenient operation, small investment, and fast returns.
Working principle
The uniform slurry is slowly fed to the spiral trough surface through the ore feeding trough installed at the head of the spiral trough for separation. The tail end of the spiral trough is equipped with a valve block product interception trough, which divides the separated products into three types according to grade along the radial direction. The position of the valve block is adjusted to change the interception width of each product, and the product gathering bucket collects and exports the intercepted multi-head ore flows separately. The cross-section of the spiral chute and the slope change of the curve are particularly suitable for the separation of fine particles.

1. Classification of spiral chutes?
According to the particle size of the ore being processed, chutes can be divided into three categories:
(1) Coarse-grained chutes, with a maximum feed particle size of 2-3 mm or more, up to 100-200 mm.
(2) Ore sand chutes, which process 2-3 mm particle-grade ores.
(3) Sludge chutes, with a feed particle size of less than 0.074 mm.
2. What is the difference between a spiral chute and a spiral concentrator?
The main differences between a spiral chute and a spiral concentrator are:
(1) The cross section of the spiral chute is a straight line or a cubic parabola.
(2) The concentrate, medium and tailings are all discharged at the end of the spiral chute, and there is no concentrate interception device in the middle of the spiral chute.
(3) No flushing water is generally added during the separation process.
