Maximize Mineral Recovery with Our High-Efficiency Spiral Classifiers – Precision Separation for Optimal Results
The spiral classifier is one of the equipment for mineral processing. It is a kind of equipment for mechanical classification based on the principle that the specific gravity of solid particles is different and therefore the precipitation speed in the liquid is different. It can filter the powder ground in the ball mill, and then use the spiral blades to rotate the coarse material into the mill feed port, and discharge the filtered fine material from the overflow pipe.
The spiral classifier mainly consists of the following components:
The spiral classifier relies on the principle that the solid particles are different in size and specific gravity, so their sedimentation speed is different in the liquid.
The slurry is stirred by spiral rotation at low speed so that fine particles are suspended in the slurry surface and overflow to the overflow weir.
Coarse particles sink to the bottom of the tank and are conveyed by the screw to the discharge port to be discharged. Generally, the coarse sand is returned to the ball mill for secondary grinding, that is, the spiral classifier and the ball mill form a closed circuit.
