    Oct 01, 2015 · In general, it can be said that by increasing simulation time, recovery of both top and bottom screens of the industrial double-deck screen increases. Fig. 4a also demonstrates the effect of feed particle size distribution on screening recovery. As it can be seen, by changing feed particle size distribution in simulations 1 and 3, screening recoveries of both top and bottom screens have …

    Sep 11, 2012 · The Feed material to the screen contains 60% (- 30mm). After screening the oversized fraction contains 10% (-30mm) undersized contains 95% of (-30mm). Calculation: Let us find the Values of A,B and C for calculating Efficiency, A= 60/100 , B = 95/100 , C = 10/100. Efficiency -1 = (A-B)/(C-B) = (0.6-0.95)/(0.1-0.95) = 0.411

    Sep 01, 2011 · However, the screening efficiency reduces to 0.647 when the deck angle is increased above this value. The decrease in efficiency results from a decrease in the effective area of the mesh and an increase in the particle velocity along the deck. This shows that the optimal screen deck inclination angle for good screening efficiency is about 15°. 5. Conclusions (1) The particles on a circularly …
