ball mill efficiency rpm

What it is the optimun speed for aballmill? - posted in Pyrotechnics: I have done aballmill, recenly finished , but the motor has toorpms, is too fast for use in aballmill(the pvc cylinder that i use , left of the shafts). With the motor i will use a 40 mm pulley , because i have a 50 mm driven pulley, in one of my two shafts.

Ballmill- Wikipedia

Aballmillis a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as theballsdrop from near the top of the shell.

Ballmilloperation is often regarded as something of a mystery for several reasons.Ballmilling is not an art - it's just physics. The first problem willballmillsis 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.

Speeds and Feeds 101 - In The Loupe

As shown above, the cutter speed (RPM) is defined by the SFM (based on material) and the cutter diameter. With miniature tooling and/or certain materials the speed calculation sometimes yields an unrealistic spindle speed. For example, a .047" cutter in 6061 aluminum (SFM 1,000) would return a speed of ~81,000RPM.
