Hydrocyclone is a classification device which uses centrifugal force to accelerate the sedimentation of ore particles. It needs pressure to feed the ore, so it consumes large power, but occupies a small area, cheap price, large processing capacity, high classification efficiency, can obtain very fine overflow products, mostly used in the second section of closed circuit grinding classification equipment.
Hydrocyclone is a kind of high efficiency grading, desliming equipment, because of its simple structure, easy to manufacture, large processing capacity, has been widely used at home and abroad. The main disadvantage of it is that it consumes more power and is seriously worn during high pressure ore feeding. The use of new wear-resistant materials, such as hard alloy, silicon carbide and other production of sand mouth and ore mouth wear-resistant parts, can partially solve this problem, in addition, when used for closed circuit grinding classification, because of its small volume, no buffer capacity for ore fluctuation, as stable as mechanical classifier.
Working principle: The fluid carrying the suspended particles enters the cyclone separator tangentially, spirals downward and creates a centrifugal field in the free vortex. The larger particles move in a spiral motion through the fluid to the outside of the cyclone separator and exit with a portion of the liquid through the cannula. Due to the confined area of the casing, an inner vortex that rotates in the same direction as the outer vortex but flows upward is established, which leaves the cyclone separator through the vortex separator and carries most of the liquid and fine particles.
The refurbishment of hydrocyclones represents one of the largest uses of alumina in the mineral processing industry. Ideally, this should be done as infrequently as possible due to the huge cost of shutting down a mineral processing plant, which can run into millions of dollars a day for large plants.
