Dry Milling — Tips: 1. Minimize moisture content of feed material; high moisture content (over 2%) can cause material to cake inside the milling chamber. 2. Continously add grinding aids or additives, whether in powder or liquid form, while size reduction is taking place. Most dry milling processes require such materials.

Thus, the higher the energy (milling speed, relative velocity of the balls, time of milling, size of the grinding balls, balltopowder 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].
