Hydrocyclone is a kind of high-efficiency classification and desliming equipment. Because of its simple structure, easy manufacture and large processing capacity, it has been widely used at home and abroad. The main disadvantage of Hydrocyclone is that it consumes a lot of power and is worn during high-pressure feeding. Serious. The use of new wear-resistant materials, such as cemented carbide, silicon carbide, etc. to make wear-resistant parts for the grit mouth and the mine mouth, can partially solve this problem. In addition, when used for the classification of closed-circuit grinding, Because of its small volume, it has no buffer capacity for ore volume fluctuations, and it is not as stable as a mechanical classifier.
Hydrocyclone first appeared in the Netherlands in the late 1930s. Hydrocyclone is a device that uses rotary flow for classification, and is also used for concentration, dehydration and selection. The structure of Hydrocyclone is very simple, mainly composed of a hollow cylinder l and cone 2. Connected. The diameter of the cylinder represents the specifications of the cyclone. The size of Hydrocyclone varies widely, from 50mm to 1000mm, usually 125-500mm. An overflow pipe 5 is inserted in the center of the cylinder, a feed pipe 3 is connected along the tangential direction, and a grit port 4 is left in the lower part of the cone. . Under pressure, the slurry is fed into the cyclone along the feeding pipe, and then it makes a rotary motion under the restriction of the cylindrical wall. Coarse particles are thrown to the wall due to the large inertial centrifugal force, and gradually flow downwards and are discharged from the bottom to become sediment. The fine particles move to the wall at a slower speed, and are driven by the liquid flowing toward the center to flow out from the central overflow pipe and become an overflow.
Hydrocyclone is a device used to separate and remove heavy coarse-grained silt and other substances in sewage. Sometimes it is also used for mud dewatering. There are two types, pressure type and gravity type, which are often made of circular column structures or metal pipes. Water enters along the tangent line from the upper part of the structure (or metal pipe) by pressure or gravity. Under the action of centrifugal force, the coarse and heavy particulate matter is thrown to the wall of the vessel and rotates downward to be discharged together with the formed thick liquid. Smaller particulate matter rotates to a certain extent and is discharged with the secondary upward vortex flow.
