Brief Introduction for Screw Classifier

Screw Classifier is widely used to pre-grading and inspection grading in closed circuits when used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified. Waste mud or water for ore sand can be separated from the ores. It’s also usually applied to ore washing, desliming and dehydration and so on.JXSC Mine Machinery Spiral classifiers mainly include four types. They are high weir type single spiral classifier, high weir type double spiral classifier, immersed type single spiral classifier and immerse type double spiral classifier. A spiral classifier is composed of a transmission device, spirals, tanks, elevator mechanism, a bottom support (bearing bush) and a discharging valve.

Working Principle for Screw Classifier

Screw Classifier machine use the work principle of different solid particles size, different specific gravity, thus  the liquid settling rate is different, a thin ore grain of float becomes the overflow in the water to leave, the coarse ore grain sinks in the tank bottom. Pushed by the spiral top discharge, mechanical classification a grading device, powder mill grinding out levels in filter, and coarse material using helical Rotary screw mill inlet, take the filter out of fine material discharged from the overflow pipe. The machine base channel steel, organism uses the steel plates welded together. Into the head of the screw axis, axis head, cast iron sleeve, wear-resistant and durable, electric and manual lifting device in two ways.

Characteristics for Screw Classifier

1, for excessive sand production technology of dry powder separation, can be very convenient control mechanism of stone powder content, meet the requirements of users.

2, suitable for a dry, medium sand production line use.

3, 0.00--0.75mm stone powder content in the 2% adjustable between-.

4, quality powder is easy to control, fineness adjustment convenient, flexible, and reliable.

5, tile-lined, very low maintenance rates.

6, uses the frequency conversion control technology, operating more simplified.

Structure for Screw Classifier

Screw Classifier mainly consists of driving device, Spirochetes, tank, lifting body, the lower bearing (axle Bush) and discharge valve components.
