Application of FMVS2030 compound vibration high-frequency fine screen in Qinxin coal preparation plant

To improve vibrating sieve bend from screening efficiency,effect of desliming and ash reduction in Qinxin coal preparation plant,FMVS2030 compound vibration high-frequency fine screen is used instead of the sieve bend. Presented structure,working principle,technical features and parameters of this screen,and then analyzed its application in coal preparation plant. Compared with the sieve bend,this screen has 13. 28% higher screening efficiency than that of the sieve bend,reducing ash content of coarse clean coal from 14. 80% to 9. 21%,with a increase of 4. 62% in recovery of clean coal,which brings considerable economic benefits.
