Here we have internal diameter of ball mill as 1.8288. So critical speed of our ball mill is nC = 42.29/√d, = 42.29/√1.8288=31.27 now Ball mills are normally operated at around 75% of critical speed, So a mill with diameter 1.8288 meters will turn at around 23.45 rpm. The mill is usually divided into at least two. بیشتر

1. When you use the ball mill for the first time. In the first time, the grinding steel balls must be added at 80% of the maximum ball loading capacity of the ball mill. And three sizes of balls, namely, large, medium and small, are required for proportioning. Different ball mill models have different ball loading capacities.

So I'm wondering what the tricks are if any. I can center on the hole as the part is fixtured. I think what happened the last time was the end mill started to break up the 3 flute tap, and the bits jammed the end mill. Tap is HHS. Since the pilot hole is 5mm (but I have no 5mm end mills) I was going to try a 4 flute 3/16 end mill.
