Product Introduction:

The Spiral classifier is one of the important beneficiation equipment in mineral processing. Spiral classifiers mainly include high-weir single screw and double screw, sunken single screw and double screw. Spiral classifier is widely used in mineral processing plants with known as diverter inbound beneficiation, ball closed-loop process or gravity for ore grade and size classification of fine clay, metal particles and pulp in the beneficiation process, desilting, dewatering and other operations in washing operations.

Working principle:The spiral classifier is based on the principle that the size of the solid particles is different, the specific gravity is different, so the sedimentation speed in the liquid is different, the fine ore particles float in the water and overflow, and the coarse ore particles sink at the bottom of the trough. A kind of grading equipment that is pushed out by the spiral to carry out mechanical grading, which can filter the material powder grinded out of the mill, and then use the spiral blade rotary blade to screw the coarse material into the mill inlet, and discharge the filtered fine material from the overflow pipe.

We provide one‑stop mineral processing EPC turn‑key service: ore sample testing, process design, full‑set equipment manufacturing, site installation & commissioning, technical training.

Performance characteristics:

1. Low power consumption: optimize the axle and reduce the friction coefficient of internal rotation to reduce power consumption;

2. High efficiency: reasonably design the distance between the spiral body and the trough body, do not block the silt material, and make the efficiency high;

3. High degree of grading: the use of standardized operations, strict requirements for welding and machining components, fully in line with the requirements of drawings and technical standards, so that the grading operations in the work are accurate, and the material particle size is clear;

4. Long life: the alloy spiral body middle tube steel is used, which is solid and wear-resistant, and has a long service life.
