# Determining the effeciency of screen on crushers product

Sep 15, 2014 It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4-ft by 8-ft screen would be acceptable. The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft. The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft

• Tips for maintaining efficiency in crushing circuits

Apr 01, 2019 Efficiency can be defined by the ratio of work done by a machine to the energy supplied to it. To apply what this means to your crusher, in your reduction process you are producing exactly the sizes your market is demanding. In the past, quarries produced a range of single-size aggregate products up to 40mm in size

1. Conduct screen analyses of the circuit feed and product samples. 2. Conduct Wi test(s) on the circuit feed (see Section 8).. Use a 1,190 m screen to close the rod mill Wi test for these purposes. Choose a closing screen for the ball mill test that is one (standard square root of 2 series) mesh size coarser than the plant ball mill circuit P80. If choos

Sep 11, 2012 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. Efficiency -2 = (C-A)/(C-B) = (0.1-0.6)/(0.1-0.95) = 0.588. Efficiency -3 = (1-C)/(1-A) = (1-0.1)/(1-0.6) = 2.25. Efficiency
