2.1.9 Crushing Power The 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

Rankin's Formula Example for Column Crushing/Buckling

 · Rankin’s formula is also known as Rankin Gordon Formula. It gives the ultimate load that column can bear before failure. If column is short, calculated load will be known as crushing load. And load will be buckling or crippling load, in case of long column. This formula only gives the ultimate load, but columns are design on safe load.
