calculation of specific power consumption of ball
The Power Consumption Calculation of a Ball Drum Mill - IdosiRecently, ball drum mills with transverse longitudinal movement of grinding bodies showed a progress the grinding process intensification. Specific energy consumption for the grinding dropped down to 30%. Current methods of power consumption calculation of a mill drive do not allow determining the power consumption.calculation of specific power consumption of ball,modeling the specific grinding energy and ball-mill scaleup8. Present paper. An effort to develop simple and efficient models for: ○ the calculation of the specific grinding energy w and. ○ the determination of the mill power draw P. (as a function of the Bond work index w i. ) Use of the above models: For ball-mill scale-up purposes.Calculation of energy required for grinding in a ball mill .The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product. Therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a.
