consumption prediction required for grinding, especially in a closed cycle, or for complex ore composed of different minerals. Based on these observations, Bond and others in AllisChalmers have developed a grinding test in a ball mill in a closed cycle until the establishment of stable recirculating load (Maxson et al., 1933). The Bond work index is a parameter which represents a measure of ...

End Use of Fuel Consumption The Manufacturing Energy Consumption Survey (MECS) collects fuel consumption by end use for six major energy sources – electricity, natural gas, coal, LPG, diesel/distillate, and residual fuel oil. Coke, an energy source used for fuel in a blast furnace, is not included as one of the six major energy sources when collecting for end use in the MECS.

The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill circulating loads of >1000 per cent. Manufacturers have countered this generally satisfactorily with pressure drops reduced by lower nozzle ring velocities and the addition of external spillage elevator recirculation systems ...

given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semiautogenous and ball mills which is based on the motion of grinding charge inside the mill. He also verified his approach with various plant data (NapierMunn et. al., 1996). In this study, power draw of 14 multicompartment cement grinding mills were calculated based on ...
