- The effect of powder filling on selection and breakage functions is investigated. At three levels of powder filling, the selection functions are determined by one-size-fraction tests. The selection function decreases rapidly with increasing powder filling. When the powder filling is very low, the breakage function appears to be higher. Because of the non-normalization of the breakage function in this work a back-calculation method for determination of the breakage function is applied. For the non-normalized breakage function, if the selection function is known, it is possible to back-calculate a normalizable breakage function which gives the best simulation results. The effect of powder filling on product size distribution can be compensated by adjusting the grinding time. The material used was iron ore.
