ball mill rpm

C.S. = 76.63 / 11^0.5 = 23.1rpm.Balland SAGMillsare driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations. Within that range the power is nearly proportional to the speed.Mill rotating speedimpacts grinding rates.

The first problem willball millsis that we cannot see what is occurring in themill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. Inball millingof dry solids the main independent variables aremill diameter,mill speed, media size, solids loading and residence time.

Optimizing theBall Mill's RPMMake sure the whole roller assembly now looks as it originally did, and rotates freely. There you go: A larger, 3/4-inch diameter drive roller, simple as that. Test-run the mill with a jar on it, and verify that the speed of the jar's rotation has increased to approximately80-90 RPM.

What it is the optimun speed for a ball mill

Oct 18, 2006· In an ideallycharged jar, at theoptimum RPM, there are multiple strikes by eachball, against each other, with the comp of course pinched between, all the way down the slope of the cascade. It's a bit hard without pictures, but theballsrubbing against each other continuously is where the work is done, not them slamming the bottom of the jar.

Jul 30, 2010· when you say plunging I think you are drilling a round bottom hole. The RPM for a 0.500" would be 2400 RPM. 4*300/0.500"=2400 For drilling I use an exception of 50%, so 1200 RPM. But plunging any endmill directly into the material is hard. You basicly have to slow it down till it stops chattering or the chatter is exceptable.
