Calculation of energy required for grinding in a ball mill Int J Miner Process 25 41-46 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
Read moreThe Bond work index W i 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 given size of grinding product the value of the work index W i
