Application Of Spiral Chute In Mineral Processing

The spiral chute is a mineral processing device based on centrifugal force and gravity. It can separate ores according to density, achieving preliminary classification, impurity removal, ore enrichment, and improved production efficiency. Spiral chutes are widely used in the beneficiation of gold, silver, copper, iron, and other minerals.

The structure of the spiral chute

The spiral chute mainly consists of a chute body, a transmission device, a spiral body, a feed box, and a mud discharge port. The transmission device drives the rotation of the auger. Both the trough and the auger are made of wear-resistant material, ensuring a long service life.

Application of the spiral chute in mineral processing

1. Preliminary grading of ore

The grade of ores is usually quite complex and requires preliminary classification. In this process, the spiral sluice can separate the ore into three different grades according to density: heavy ore, medium ore, and light ore. This facilitates subsequent magnetic separation, gravity separation, and other operations.

2. Removal of impurities

Ore usually contains some impurities, such as quartz and feldspar. These impurities have a significant impact on the grade of the ore. The spiral chute can separate these impurities from the ore through the internal water flow, effectively improving the ore grade.

3. Ore enrichment

Different minerals in an ore have different densities, so the spiral chute can be used to enrich the ore. By adjusting the parameters of the sluice, mineral-rich ores can be separated, thereby improving the ore grade.

4. Improve production efficiency

Using the spiral chute to process ore can solve multiple problems in a single operation. This can effectively improve production efficiency and reduce equipment maintenance and repair costs.
