Commodity £ºHydrocyclone
Hydrocyclone Instruction£ºHydrocyclone utilizes centrifugal force to classify, usually classify or shuck off mus before fine mineral processing, it is nowadays the most efficient classifier.
Construction of Hydrocyclone£ºthe upper is in the shape of cone, There is a mineral-feeding tube on the columniform cannon tube, and a central overfalling tube is on the above of cone, the overfalling tube is connected with the buffer or exterior tube directly, besies, there is a grit chamber that can be used to rough or big ore-sand, In order to reduce the abrasion of equipment, some abrasion-resistant materials including diabase, ceramic, silicon carbide or rubber can be adhered to the inner of the mineral feeding mouth and grit chamber etc.
Principle£ºore-mud can enter the drum with the help of a certain of pressure (usually 0.5 to 2.5 kg / cm) and velocity (about 5 to 12 m / sec) that caused by slurry pump, and the ore-mud will rotate with the surfacd of drum, and cause quite strong centrifugal force, rough or big ore-sand will move downwards with the force of centrifugal and gravity. Then they will be discharged from the underside of the cone, whereas some thin sand will be discharged from the overfalling pipe.
There are many factors that affect the efficiency of Hydrocyclone,for example, when the diameter increaes, the productivity and separating granularity will increase, the separating efficiency will decrease; some other factors, such as the size and shape of feeding mouth; the pressure when ore-mud enter the feeding mouth; sizes of overfalling pipe and sand-outputting poll, also the ratio of the diameter; the size of cone and the concentration of the ore-mud and so on.
its advantages£ºit has no locomotor part, simple construction, the productivity of each volume is fine, has small space, and high efficiency of separation(up to 80%¡«90%), the processed mineral granularity is fine and thin, low cost,its disadvantages: the accessories are easy to abrase, much power consumption, the pressure and concentration of feeding, and the granularity have strong effect on the separation. |
