A Brief History of the hydrocyclone

Hydrocyclone early in the 20th century in the late 1930s in the Netherlands appears. Hydrocyclone is the use of rotary flow grading equipment, and is also used for thickening, dewatering result sorting, its structure is very simple, is dominated by a hollow l and a tapered cylinder 2 is connected from. cyclone diameter of the cylinder represents the specification. its size varies greatly from 50mm to 1000mm, typically 125-500mm. inserted in the center of the cylinder an overflow pipe 5 ,weed sprayer there is tangentially connected to the mine pipe 3, in the lower left Spigot cone 4 slurry under pressure,? along the ore fed into the cyclone tube inside, then limit the cylindrical wall perishable rotary movement of coarse particles due to inertia and centrifugal force wall was thrown and gradually downward flow discharged from the bottom of a grit. fine particle moving speed of the lower wall, is driven by the liquid flowing toward the center from the central overflow pipe outflow become overflow.
Hydrocyclone is a high efficiency rating, off the mud equipment,garden sprayer backpack due to its simple structure, easy to manufacture, processing capacity, has been widely used at home and abroad. Its main drawback is the large power consumption, and in the high-pressure feed Mine is badly worn. adopt new wear-resistant materials, such as cemented carbide, silicon carbide and other production Spigot and wear parts to the mine mouth can partially solve this problem, in addition, when used in closed-circuit grinding of grading, because of its small volume, no buffer against fluctuations in ore ability as mechanical grading machine work stable.
