Development and prospect of gravity-fed three-product heavy media cyclone
As an important sorting equipment in the coal preparation industry,the gravity-fed three-product heavy medium cyclone has the characteristics of simple structure,high sorting accuracy,energy conservation and environmental protection.The development and application history of the gravity-fed three-product heavy medium cyclone in China is introduced,the performance characteristics and application effects of the three-product heavy medium cyclone in different periods are analyzed,and the development of the coal preparation process and equipment of the three-product heavy medium cyclone is prospected.It is considered that the continuous research on gravity-fed three-product heavy medium cyclone technology process should be carried out for the influence of raw coal and slime dense medium cyclone process parameters on the separation process,the influence of magnetic separation process parameters on the magnetic separation process effect,and the separation process of middling coal magnetic separation tailings.In terms of heavy medium cyclone equipment,it is necessary to reduce the lower limit of sorting,improve sorting accuracy,further improve the accuracy and reliability of detection equipment,and extend the service life of the cyclone.
