BLL spiral chute is to make separation 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 difference 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 . Pulp in the heavy mineral grains settling faster convergence along the spiral gradually inward edge of the end, the form of concentrates produced. Light mineral deposition slowly, at a surface mine flow, velocity fast, centrifugal force, sub-ah horizontal circulation under the effect of gradually expanded along the line gradually moved towards the outer edge of the spiral, the end, the form of tailings output.
