WEBTo find the power at the mill pinion, multiply an E value by the circuit solids feed rate (feed rate of dry solids to primary mill or the dry solids flow rate of product in the cyclone overflow). Power as kW = E * (t/h dry solids) A ball mill can safely operate at 90% of its motor rated power, so choose a motor size like this:
WEBTo calculate the feedrate we need to find out the feed per tooth or the feed per rev. Again a good starting point using a good quality endmill would be .002" per tooth. So if we had a 4 flute cutter this would be .008" per REV, (4 X .002"). Now you can use the second formula using the rpm we just calculated,
WEBAug 1, 2013 · At low feed rates, impact forces are considered to dominate over abrasion (Gates et al., 2007) and Howat and Vermeulen (1988) have observed that at low feed rates, when the residence time of particles within the mill is long, the consumption of grinding media is high and the grind is fine.
