The aim of our research paper was to apply response surface methodology for modeling of grinding Dolomite ore using ball mill with the parameter considering:
1. Time of Grinding.
2. Ball Size.
3. Feed Quantity.
4. Feed Size.
Specific energy consumption also decreases with feed quantity at all ball sizes. Energy savings, expressed as a percentage of the energy consumption. Using these set of experimental data obtained, the models are developed to show the effect of each parameter and their interactions on the product. Maximum Specific surface is obtained at higher speed of the mill (66 rpm in our case). This also correspondence to the speed at which we have minimum energy consumption per unit surface area generated. As the grinding time increases specific surface increases. As the specific surface increases, power consumption also increases.
