Spiral classifier by means of different solid grain sizes, different specific gravity, thus settling velocity different principles in the liquid, fine mineral particles floating in the water to overflow, coarse mineral particles sink to the bottom. Discharged into the upper part of the spiral, to a hierarchical classification of mechanical equipment, can feed powder mill grind level within the filter, and then use the coarse material spiral piece rotary vane screwed mill feed, the filter out the fine material discharged from the overflow pipe. The machine base is made of channel steel, steel plate welded body. The head of the screw shaft, the shaft head, using cast iron sleeve, wear durability, improve device-electric and manual.

Spiral Classifiers are usually suitable for the following situations:
- 1. Separation of fine particles and liquid from coarse particles;
- 2. Separation of light particles from heavy particles;
- 3. Separation of the particles into a number of products graded according to size;
- 4. Separation of liquid from solid particles;
Spiral classifier mainly high weir single screw and twin screw, low weir single screw and twin screw, sinking several single spiral and double spiral classifier, low weir now use very little, mainly high weir type and sinking and XL spiral classifier.
Spiral classifier is widely used in the concentrator and mill closed loop process dubbed minute drive shunt mineral sands, or gravity concentrator to grade ore and fine clay, and metal beneficiation process for pulp particle size grading and washing job off the mud, dehydration and other operations. The machine has a simple structure, reliable, easy to operate.
The machine base is made of channel steel, steel plate welded body. The head of the screw shaft, the shaft head, using cast iron sleeve, wear durability, improve device-electric and manual.
