  • Predicting Steel Media Consumption Grinding

    Predicting Steel Media Consumption Grinding

    A big majority of people is still using the old Bond equations without asking themselves do 950 g/t or 1,100 g/t of steel consumption in the ball mills make sense? When we apply our experience from the last 20 years we see right away that steel consumption in the range of 1,000 g/t in a ball mill is not correct, and that is a fact.
