Specifications

Spiral chute is applicable to materials of different feeding granularity, density, and grades.

Spiral Chute

This spiral chute is a combination of benefits of a spiral concentrator, a spiral chute, a table concentrator, and a centrifugal ore separator. It is an ideal tool for mining and mineral processing applications, especially on riversides, strands, beaches, and river ways. Our spiral chute comes with reasonable structure, simple installation, easy operation, high capacity, light weight, low noise, good rust, moisture and corrosion resistance. In addition, it is fully applicable to materials of different feeding granularity, density, and grades.

 

Applications:
Spiral chute is suitable for fine materials of 0.3-0.02 mm granularities, such as iron ore, ilmenite, chromite, pyretic, zirconite, rutile, monazite, xenotime, tungsten ore, tin ore, tantalum ore, colombite ore as well as other nonferrous metal, rare metal and nonmetal minerals of different proportions.

 

Working Principle:
The sand pulp is first send to the two inlets of the spiral chute. After added water for appropriate pulp density, the pulp swirls down and generates a centrifugal force which separates the ores and sands. The ore concentrate flows into the hopper and is collected through a pipeline. The tailings are discharged by a sand pulp. Thus, the whole mineral process is finished.
