#### Efficiency of Vibrating Screens bulkonline

Oct 21, 20040183;32;Dear all, How do we calculate the efficiency of screening? For a PU deck Vibro screen for 30 mm separation ( cap 62.5 TPH, Bulk Density 0.55 T/m3), if undersize fraction contains 8 % , +30 mm fraction and Oversize contains 5% , 30 mm fraction, what shall be screening efficiency? What is the industry standard for screen efficiency?
