high-energy ball mill. The model was then used to estimate the energy transfer in milling of iron . subjected to milling in the current study. The mass ﬂow rate of the cooling water was main- . vial and one just given energy by spindle. The basic energy balance during the milling process in the simoloyer can be represented as20 E in .
Grinding raw materials needs lots of energy. Tube mills had been used for grinding but the energy efficiency level was lower. Therefore the introduction of highly efficient . ball mill. 2 The remaining time of raw materials in this type of mill is much shorter than that in tube ball mill; therefore the crushing . In case that the .
