Product Description

Spiral Classifier Introduction:
Spiral classifier is widely used for classifying materials in the mineral processing flow as well as the desliming and dehydrating in the mineral washing operating process. The spiral classifier generally forms a closed processing flow. Spiral classifier is mainly composed by transmission device, screw, cell, movable lift, lower seat (bush) and discharge valve. Spiral classifier is a kind of classifying machine that adopt the principle of settling speed difference according to different material sizes and specific gravity.
Spiral classifier of Hongji Group is classified into two types: single spiral classifier and double spiral classifier.
Features of spiral classifier:
1) Simple structure;
2) Convenient to operate;
3) High efficiency;
4) Low cost.

Spiral separator Application:
Rutile,ilmenite and zircon concentration.Iron ore,chromite and manganess beneficiation.Tin,tantalum and ore concentration.Gold,native copper and base metal recovery.Silica sands processing.Titano-magnetite concentration.
Feature:
Reasonable structure and small occupation area.High recovery,high efficiency,and precise separation.Light in weight,rush and corrosion resisitant.
Spiral chute is used 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 basesd 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 produces as concentrate.Light minerals settle slowly and flow fast in the surface layer of ore flow with large centrifugal force and gradually move towards the outer edge along the expanding helix before finally being produced as tailings.
