  • Design, Construction and Performance Analysis of a 5 KgLaboratory

    a) Milling Sizing. The Bond's method was used in sizing the laboratory ball mill. This method is based on two power calculation approaches used in ball and rod mill design processes due to its simplicity and workability. The first approach, which is specific power calculation, determines the power required to grind an ore
