Glass fibre reinforced plastic spiral chute

Products Description:
Spiral are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. It has extremely good performance and effects in processing placer of beach, riverside, seashore and stream. Jiangxi Shicheng mine machinery factory spirals are made of polyurethane lined fiber glass with wearable corundum inner surface. Generally there are 5 turns in one start, single, twin, triple and quad starts available per column to suit capacity requirments.

Application
Rutile, ilmenite and zircon concentration.
Iron ore, chromite and manganese beneficiation.
Tin, tantalum and ore concentration.
Gold, native copper and base metal recovery.
Silica sands processing.
Titano-magnetite concentration.

Feature&Benefits
Reasonable structure and small occupation area.
High recovery, high efficiency, and precise separation.
Light in weight, rush and corrosion resistant.
Simple installation and Minimal maintenance requirements.
Low operating cost and long operating life.
Reliable running with minimal operator attention.
Strong adaptability to fluctuation of feeding amount, density, size and grade.

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 prior 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.
