Structural parameters of gravity spiral chute equipment

Structural parameters of gravity spiral chute equipment

This gravity spiral chute equipment applies to sort non-ferrous metals, precious metals and non-metallic mineral body with particle size of 0.3 – 0.02 mm as well as differences in the proportion, such as thin material of iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphorus B ore, tungsten ore, tin, tantalum ore, niobium ore, etc. This equipment has stable sorting process, easy control, wide mineral concentration range, high enrichment, high recovery, small footprint, small water consumption, simple structure, without power, large capacity, easy installation and operation, small investment and other advantages.
The gravity spiral chute has the main advantages of simple structure, low investment and production cost and the high processing capacity. At present, the gravity spiral is widely used for processing tungsten, tin, gold, platinum, iron, and some rare metal ores.
Summary of structural parameters
1. Diameter
The processing power of the spiral chute is mainly determined by the diameter of the spiral chute, its size is proportional to the square of and diameter.
2. Screw pitch
Screw pitch size determines the size of the longitudinal inclination of the spiral chute, and be represented by the ratio of the pitch and the diameter.
3. Cross section
For large size materials, we should use larger horizontal angle β, and the flow depth and flow velocity are both large. Conversely, we should use the lateral cross section with smaller inclination.
4. Cylinder number
The cylinder number decides the length of selection line. The cylinder number varies with the nature of the selected materials, often need to be determined by experiments, 3-5 circles is appropriate.
5. Chute pavement
The requirements on pavement: (1) wear-resisting (2) smooth (3) wetting (4) the coefficient of friction.
The agitation vat is used for the stir of the slurry in the flotation operation to make the pulp fully mixed with the flotation agents, creating the conditions for the processing operations. It can also be used for the stir of other non-metallic minerals.
