Design, Fabrication and Testing of a Double Roll Crusher
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

Assessing the energy efficiency of a jaw crusher
Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
