Abstract
Silica sand is widely used as a building material and as raw material for glass, but it is necessary to control the particle size or the particle size distribution of silica sand depending on the industrial field applied. It is important to develop a technique to design particle size and to apply a scale-up method for the comminution and classification processes. In this study, a simulation was conducted by applying parameters of comminution kinetics and the partial classification efficiency equation to closed-circuit grinding process. A scale-up technique was established from the relations between the parameters of the comminution kinetics and the mill diameter. In this way, we could obtain the required product size distribution by this simulation method and this scale-up technique.
