The use and principle of Spiral Chute
The equipment is suitable for sorting iron ore, ilmenite, chromite, pyrite, zirconite, rutile, monazite, phospho-ethyl ore, tungsten ore, tin ore, tantalite, niobium ore and other non-ferrous metals, rare metals and non-metallic ore objects with specific gravity difference.
The equipment has a stable separation process, easy to control, ore concentration allowed to change a large range, high enrichment ratio, high recovery, Small footprint, less water consumption, simple structure, no power, large processing capacity, simple installation, convenient operation, small investment and quick effect.
Working principle of the glass fiber reinforced plastic spiral chute is according to the useful minerals and gangue minerals of the differences in density, grain size, shape, in spiral bevel pulp centrifugal flow membrane of the movement, in the comprehensive force field of gravity and centrifugal force, the use of different particles by gravity, water pressure and friction, realizes the useful minerals and gangue separation.
In addition to the downward spiral motion, the water movement in the spiral groove also circulates horizontally. The upper flow velocity is fast, resulting in a large inertial centrifugal force, which is thrown to the outer edge of the groove. The lower water flow adjacent to the bottom of the trough has slow rotation speed and small centrifugal force, and flows from the outer edge to the inner edge under the action of gravity, resulting in secondary reflux.
The heavy ore particles in the pulp settle quickly, gradually move to the inner edge along the convergent spiral, and then produce in the form of concentrate. Light minerals settle slowly and are located on the surface of ore flow with fast velocity and large centrifugal force. Under the action of transverse circulation, they gradually move to the outer edge along the expanding spiral line and are produced in the form of tailings.
