Sažetak
Population balances are the most useful tool in solving many engineering problems including comminution process modeling. Studying batch grinding in terms of material balances inevitably demands for determining two basic functions: breakage rate function, also known as selection function and breakage distribution function. They depend on many factors such as initial fraction size or distribution of sizes, material characteristics, comminution machine characteristics etc. This paper investigates the influence of process parameters (grinding ball material and diameter, mill speed, relative ball filling ratio) on dry batch grinding behavior of single size fraction (– 3.36+2.25 mm) dolomite ground by using two different planetary ball mills. Effects are expressed in terms of breakage rate (selection) function and breakage distribution function.
