Oct 19 2006 what it is the optimun speed for a ball mill posted in pyrotechnics i have done a ball mill recenly finished but the motor has too rpms is too fast for use in a ball mill 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 in the other side of my shafts there are two 40 mm
Two fluted end mills can be used to plunge into a workpiece like a drill 2 and 3 flutes are generally for aluminum 4 flutes is better for stainless steel more flutes are better cutting but come at a higher price end mills with more than two flutes should not be plunged into the work fillets can be produced with ball end mills
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent it is especially difficult to teach mill
For example a lead might be shifted from 500 mm to 505 mm to shift the ball bearings in a different direction inside the ball nut this is the preferred method when considering compactness but
Difference between sag mill vs ball mill oct 12 today we will learn about difference between sag mill vs ball mill a mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding crushing or cutting this commutation is an essential part of many process various kinds of mills are there with which different material processing takes place
