2 GEARLESS MILL DES The gearless mill drive eliminates ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. Building a track record
Located at Kennecott Utah Copper near Salt Lake, this mill uses a ring-motor drive, Figure 5. The SAG mill is followed by two 20-ft diam., 7,500-hp gear-driven ball mills.

Well look at when youre likely to see ball mills and in which industries, and then well have a look at some of the interesting design and operational considerations associated with a ball mill. So lets start first by going through some of the main parts of a ball mill. We use a three phase motor to drive the ball mill. That is this item here.
Configured to replace a generator motor application, the low voltage Allen-Bradley AC drive has the torque control capability to operate at the six hertz required by the ball mill for spotting. The drive can separate and independently control motor flux and torque producing current, allowing it to deliver full torque down to zero speed.

May 12, 2000018332Abstract 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.
2. From the ball mill discharge size distribution calculate the 75 as 100 26.5 73.5 75 . 3. Calculate the CSE as the average 80.7 73.5 247 2 77.1 75 . In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 s. This means that
