Abstract

The grindability properties at different powder filling ratio of calcite samples belongs to Afyonkarahisar region (Turkey) were investigated at batch grinding conditions based on kinetic model. For this purpose, firstly, five different mono-sized fractions were prepared between 1.7 mm and 0.106 mm formed by a 2 sieve series. Si and Bi,j (selection and breakage distribution functions) equations were determined from the size distributions at different grinding times and the model parameters (Si, at, α, γ, β and фJ ) for different powder filling ratios. Experimentally determined data were statistically compared with data obtained using model parameter from MODSIM© simulator program
