Get PriceThe required crushing power is a function of Bond work index, capacity and the reduction ratio. Adopting Gupta and Yan [5] the power is given by, P = Q.R d.w i where Q = crushing capacity, Rd = reduction ratio (x 1 /x 2) and wi = work index. In this work Q = .356 t/hr and x 1 = 7.5mm. A roll gap of 5mm had already been specified and x 2

Get PriceJan 01, 2016 The models for determining the power required for operating jaw crushers have mostly been derived using Bond’s work index. While these gave satisfactory estimations of power, it must be remembered that Bond’s expression was derived using a tumbling mill where the forces of comminution are not quite the same as that in jaw crushers.
