3 ·Under the action of pressure the ore slurry enters the shell along the tangent direction of the pillar body And rotates in the hydrocyclone shell The coarse particles or the dense particles enter the periphery of rotary current due to them get the larger centrifugal force At the same time the coarse particles downward flow with ore slurry
Improved understanding of the variables that influence hydrocyclone performance is of increasing interest to the iron ore industry where hydorcyclones are widely used to deslime fine ore In many cases the impact of particular variables is not quantified sufficiently well experimentally to ensure that industrial performance will match expectations The current work focused on developing
3 ·The structure of the hydrocyclone is relatively simple Its upper end is a cylindrical part and its lower part is a conical container The slurry is fed into the cyclone at a certain speed generally 5 to 12 meters per second along the tangential direction and obtains a rotary motion thus generating a large centrifugal force usually tens of times or even hundreds of times
