Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. 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.
This machines are divided into single spiral classifiers and double spiral classifiers. Beside, they are also divided into high weir spiral classifiers and submerged spiral classifiers. High weir classifiers are usually used for the classification with particle size of below 100 meshes. Submerged classifiers are usually used for the classification with particle size of below 200 meshes.
And for meeting different requirements to process different ores,spiral classifier always is equipped with belt conveyor and trommel scree with feeding hopper,this combined plant is popular used in sand washing.

The (left, right) spirals driven by the transmission mechanism rotates in the water tank. The finely grained slurry enters the water bank from the feed inlet at one side and forms one slurry precipitation zone, whose surface area and volume depends on the value of the water tank's inclination angle and the height of overflow edge. The spirals rotating at a low speed play a certain stirring role. After the slurry is stirred, the light and fine particles float above the surface and overflow from the overflow edge. Then they flow into the next working procedure of ore dressing. The heavy and thick particles sink into the bottom of the water tank and become return sand which is transported by the spirals to the ore discharge mouth for discharge.
