Introduction

Spiral chute or gravity chute is suitable for fine materials which size is 0.3 - 0.02 mm like iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten ore, tin, tantalum ore, niobium ore and other non-ferrous metals with a specific gravity differences, rare metals and non-metallic mineral. The sorting process of the gravity spiral chute is stable, and it is easy to control. What’s more, spiral separator allows a wide range of changes in ore concentration, with high enrichment ratio and high recovery rate.

Fote is a famous screw separator manufacturer and supplier with high reputation. The spiral chute price is quite reasonable and the quality is very good.

Spiral chute

Application of Spiral Chute:

Spiral chute is suitable for materials with separation particle size between 0.3-0.02mm like iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphorus ore, tungsten, tin, tantalum, and also suitable for non-ferrous metals, rare metals and non-metallic objects with ratio differences. Fote spiral chute has the advantages like stable operation; large range of feed density; high enrichment ratio and high recycle rate.

Advantages of Spiral Chute:

Spiral separator has synthesized the advantages of beneficiation chute, spiral separator shaking table, centrifugal separator and it is the optimal equipment for mining and ore separation especially for placer mining of beach, river, sand beach and stream. It can be classified into gravity spiral chute and construction chute. Spiral chute has the characteristics like reasonable structure; easy installation; small footprint; easy operation; stable operation, clear ore separation; large capacity; high efficiency; high enrichment ratio and high recycle rate.

Characteristics of Spiral Chute:

1. Small footprint.

2. Water saving.

3. Simple structure.

4. Energy saving.

5. Large capacity.

6. Easy installation and operation.

7. Small investment and quick effect.
