Milling Energy - an overview | ScienceDirect Topics

Thus, the higher the energy (milling speed, relative velocity of the balls, time of milling, size of the grinding balls, ball-to-powder weight ratio, etc.), the higher the temperature rise. Second, it is possible that exothermic processes occurring during the milling process cause the powder particles to ignite and generate additional heat [13] .
