Grinding Rolls Composition

Sep 01, 2009 Specifically, the energy split factor, S, is defined as the energy expended in grinding each of the components alone divided by the energy consumed in grinding the mixture such that the same degree of fineness is attained for that component: (2) S i = E (i a) / E (m) where S i is the energy split factor for component i, E(ia) is energy expended in grinding component i alone, and E(m) is the energy consumed in grinding the mixture to attain the same degree of fineness of component i
