Spiral Chute

Product introduction

Spiral chute is the equipment for mining and beneficiation, especially the placer mining on the seashore, riverside, sand beach and stream road is more ideal. The product has the characteristics of reasonable structure, simple installation, small footprint, easy operation, stable beneficiation, clear ore separation, large processing capacity, high efficiency, high beneficiation and enrichment ratio, high recovery rate and reliable operation. It has the advantages of light weight, moisture-proof, rust-proof, corrosion-resistant, strong adaptability to fluctuations of ore feeding amount and concentration, particle size and grade, and no noise. When the spiral chutes are widely used in the industry, they should be configured in groups, and the multi-pipe distributor should be used for quantitative feeding. The spiral chutes should be continuously arranged in rows to save floor space.

Product application

Application materials: iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, ethidite, tungsten ore, tin ore, tantalum ore, niobium ore and other non-ferrous metals with different specific gravity , rare metal and non-metallic minerals.

Equipment advantages: The spiral chute has the characteristics of reasonable structure, simple installation, small footprint, easy operation, stable beneficiation, clear ore separation, large processing capacity, high efficiency, high beneficiation enrichment ratio, high recovery rate, and reliable operation. Light, moisture-proof, rust-proof, corrosion-resistant, strong adaptability to fluctuations in ore feeding amount and concentration, particle size and grade, and no noise.

Working principle: erect the spiral chute, calibrate the vertical line, fix it in a suitable position with iron frame or wood, send the ore sand to the two feed ports on the top of the screw by the sand pump, add supplementary water, adjust the concentration of the ore paddle, The pulp naturally swirls from high to down. The ore pulp produces an inertial centrifugal force in the rotating inclined surface flow rate. The ore pulp expands to the outer edge of the spiral groove under the action of centrifugal inertia under the action of gravity and centrifugal force due to the difference in specific gravity, particle size and shape of the ore sand. As a result, the flow characteristics of thin flow layer at the inner edge and low flow velocity, and thick flow layer at the outer edge and high flow velocity are formed, which separates the ore from the sand. Finally, the concentrate, medium ore, tailings and sludge are respectively taken out through the ore separation valve and the ore carrying tank, so as to realize the separation.
