A drive system consists of drive motors and ball lead-screws. The control unit sends the amplified control signals to actuate drive motors which in turn rotate the ball lead-screws to position the machine table or cause rotation of the spindle. 2. Power drives Drives used in an automated system or in CNC system are of different types such as

design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings. For gearless drives, motor torque ...

Abstract: The time has come to re-think the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor options to meet these restraints.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

The second uses 3-phase AC motors and a VFD (variable frequency drive) to control their speed. It's fair to say the latter is closer to industry practice. It's also fair to say that we hear a vocal International voice against the DC motor approach because for some reason they don't seem to be able to get reasonably priced controllers that will work with their AC (mains) power …

The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. The motor was mounted using screws on only one side, which were deliberately left loose.

A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor, gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives.
