Advantages

Spiral classifier is one of the equipment for ore mining. It is a kind of equipment for mineral classification based on the principle that the specific gravity of solid particles is different and the speed of precipitation in the liquid is different. It can filter the material powder from the mill, then screw the coarse material into the mill inlet with the spiral slice, and discharge the filtered fine material from the overflow pipe. Spiral classifier short for the classifier. The classification machine mainly has the High Weir type single screw and the double screw, the sinking type single screw and the double screw four kinds of classification machines. The classifier is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower bearing (Bush) and a discharge valve. Spiral classifier is widely used in mineral processing plants with a ball mill as a closed-circuit circuit to separate the flow of ore sand, or used in gravity concentrator to grade ore sand and fine mud, and metal beneficiation processes to grade the size of ore pulp And washing operations in the Desliming hopper, dehydration and other operations.
spiral classifier features:
1. Low power consumption; 2. Heavy-duty, long working life; 3. Powerful self-contained spiral lifting device; 4. Continuous spiral raking; 5. High classifying efficiency; 6. Wide choice of weir height; 7. Rigid tank and substructure; 8. Wide choice of tank design; 9. A wide range of industries serviced.

Product Structure

Spiral classifier is by means of solid particles of different sizes, the proportion of different, thus settling velocity in liquids of different principles, fine mineral particles floating in the water to overflow out of coarse mineral particles sink to the bottom. Discharged from the screw into the upper part, to a hierarchical classification of mechanical equipment, can mill to grind the material powder level in the filter, and then use the course material helical screw rotary vane into the mill feed, the filter out the fine material is discharged from the overflow pipe. The machine base is made of a channel steel body with steel plates welded together. Into the head of the screw shaft, shaft, using pig iron, wear-resistant and durable, lifting devices of electric and manual.
The main types of the spiral classifier are high Weir single screw and double screw, low weir single screw and double screw, sinking single screw and double screw Mainly High Weir type and sinking type and XL spiral classifier.
