BLL Glass Fibre Reinforced Plastic Spiral Chute

BLL FRP spiral chute for sorting of fine (including fine particle size) of metallic minerals such as iron ore, ilmenite, chromite, sulfur iron ore, tungsten tantalum ore, gold placer, beach monazite, rutile, zircon, and there is enough difference between the proportion of other metals and non-metallic mineral sorting. This product is the only designated the former Ministry of Geology and Mineral production, the implementation of industry standards.

Spiral chute is based on useful minerals and gangue minerals in the proportion of size and form of the differences in dynamic spiral bevel produces centrifugal slurry flow membrane, gravity and centrifugal force in the overall force field, the use of different particles suffered Gravity, hydrodynamic pressure and friction to achieve the useful minerals and gangue sorting. Spiral slot except for the water moving downward spiral, but also for the horizontal circulation. The upper water flow faster, have a greater inertia centrifugal force, Shuaixiang the outer groove. Adjacent to the lower bottom water with slow rotation, centrifugal force is small, the gravity flow from the outer edge of the inner edge, resulting in secondary reflux. Pulp in the fast settlement of heavy mineral particles, along the convergence of the inner edge of the spiral gradually Chen, and finally to the form of concentrates produced. Slow light mineral deposition, the surface flow in the mine, flow speed, centrifugal force large role in the horizontal circulation, gradually expanded along the spiral gradually toward the outer edge of the final output in the form of tailings.

Laboratory BLL Glass Fibre Reinforced Plastic Spiral Chute is applicable for separation of fine-grained (including micro-grained) metallic minerals such as iron, ilmenite, chromite, tungsten-tin ore, niobium-tantalum ore, gold placer, seashore monazite, rutile and zircon as well as other metallic and non-metallic minerals with adequate difference of specific gravity. The product is made by the only maufacturer designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

Spiral Chute is to make separations of useful minerals from gangues by use of the different particles subject to gravity, hydraulic pressure and friction in the multi-force field through dynamic centrifugal flowing membrane of slurry produced on the inclined surface of spiral based on the differences of useful mineral and gangue in specific gravity, particle size and shape. Water in the spiral chute runs downward spiral movement and also flows in circulation transversely. Water in the upper layer run fast, generating centrifugal force with large inertia to toss toward the outer edge of the chute . Back-flow of water in the lower layer adjacent to the chute bootom runs slowly with small centrifugal force and flows from the outer edge to the inner edge with the action of gravity, generating secondary back-flow. Particles of heavy minerals in slurry settle rapidly and gradually moves toward the inner edge along the converged helix prio to finally being produced as concentrate. Light minerals settle slowly and flow fast in the surface layer of ore flow with large centrifugal force and gradually move toward the outer edge along the expanding helix before finally being produced as tailings .
