Spiral classifiers are widely used for separation plant. They can be combined with ball mill to form a closed circuit for preliminary classification and check classification, sometimes they can be applied for ore washing, desliming and dewatering as well. As the important part of beneficiation line, spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements. According to the theory that the deposition rates are quite different because of different solid particles' specific gravity, the spiral classifier is not only able to clean the ground mineral ore, but also separate the particles briefly.

Spiral Classifier Structure

Sprial classifier has four type,they are immerged single spiral classifier and immerged double spiral classifier, high weir spiral classifier and submerged spiral classifiers. If the overflow edge is higher than the center line of spiral shaft and lower than the external diameter of   spiral at the overflow end, the spiral classifiers are high weir ones. If the   overflow edge is higher than the center line of spiral shaft and also higher   than the external diameter of spiral at the overflow end, the spiral classifiers   are submerged ones. 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.

Spiral Classifier Application

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.

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.
