I went with 58 inch diameter balls which seem to work well in a mill this size i have been powering the ball mill with my bench variable power supply so i could fine tune the rotation speed i wanted it to turn as fast as possible to speed grinding but not so fast that centrifugal force pins the balls to the wall of the drum preventing them

Before any calculation is made you need to know what the motor rpm is at the shaft either stated on the motor label or taken with a tacho or whatever other means once you get that multiply this rpm by 4 and divide the result by 10 to get the bandwheel rpm i presume the bandwheel and the 10 inch pulley are on the same shaft

Feb 07 2018 running it too fast or too slow can impact tool life determining the right speeds and feeds for your tool and operation can be a complicated process but understanding the ideal speed rpm is necessary before you start running your machine to ensure proper tool life running a tool too fast can cause suboptimal chip size or even catastrophic tool failure
The biggest challenge with ball nosed end mills of various kinds is slow nose speed as you get closer to the tip the diameter on the ball gets smaller and smaller finally going to zero as a result the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut be sure to keep this in mind when
The saw has 20 inch wheels does that number seem right also what should the blade speed be forum responses solid wood machining forum from contributor j if i remember correctly you want to be between 700800 fpm youd be good with a 1725 motor i think i had a 30 saw 4 pulley on the motor and 12 on the saw with a 1725 rpm 5 hp baldor
