High Efficiency Screw Classifier/Spiral Classifier For Gold Ore Mining Plant

High Efficiency Screw Classifier/Spiral Classifier For Gold Ore Mining Plant

spiral classifier Processing ability: 0.15-6 t/h
Spiral diameter: 300-3000 mm
Applied material: iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten, tin, tantalum, niobium, etc.

 Spiral classifiers separate the fine waste material from the oversized material that needs to be sent back to the regrind circuit for further size reduction in ore processing. They also serve a dual purpose as a dewatering screw, when the amount of water on site is at a premium.

During classification, the lighter material floats through to the tailings, while the heavier material rides the spiral to be deposited in another container. Hengxing factory 's spiral classifiers are engineered to provide years of reliable service.

The Handling Materials and Function of Spiral Classifier:
spiral classifier is applied to iron, tin, tungsten, tantalum, niobium, gold, coal, monazite, rutile, zircon and other metal, nonmetal minerals with enough specific gravity dispersion of granularity ranged from 0.02 to 0.3mm.

In the Mineral Ore Beneficiation Plant, generally ,use the high weir spiral classifier with the ball mill to form closed circuit.

Spiral classifier Working Principle

The grinded pulp is fed into the spiral classifier tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine particles rice, and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center which is under screw shaft, and is underneath overflow end.

Features and advantages of concentrating spiral classifier:

1).Spiral classifier is Simple structure, reliable running and easy operation.

2).It mechanically classifies through the mechanism of different sedimentation speed of solid particle in liquid due to different size and different specific gravity.

3).It can classify the ground material powder from the grinder, spiral the coarse grain into material inlet of grinder through the spiral chip, and discharge the classified fine grain from overflow surface.

4).Its base is made from channel steel, and its body is welded from steel plate.

5).The lower support of spiral bearing is of engine-bearing structure of good wear resistance and durability.

6).The spiral classifier lifting device is of electric and manual mode.

Erect the Spiral Classifier, calibrate the perpendicular line and fix it in a proper position with iron structure or wood. Send the mineral sand with the sand pump to the two feeding mouth on the top of the spiral chute, add make-up water to adjust the density of the ore pulp, and the ore pulp will naturally rotationally flow down and produce an inertial centrifugal force in the rotary slant flow. The gravity and the centrifugal force will separate the ores and sand according to the proportion, granularity and shape of the ore sand, and the ore concentrate will flow into the concentrate funnel and be discharged with the pipe and the tailings will flow to the tailing funnel and be discharged to the sand tank with the pipe and drained by the sand pump to complete the whole separation process.
