The driver is a Gecko G540 and will handle up to 50 volts DC for the motors. As you said, speed is of little consequence to me. I have 20 tooth pulleys for the motors and either 48 or 60 tooth pulleys for the ball screws. Here's the YAxis motor mount. It will be attached to the mounting arm with two 5/16" bolts through the 1 5/8" long slot.

FLSmidth selected watercooled motors with automatic brush lifting system for plant expansion
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
Induction Motors [2]. Figure 3 shows a ball mill with a dual pinion drive 2x 6500 kW with low speed induction motors (LSIM). The dual pinion drives demand tight tolerances in the torque between the two motors [2] to dynamically equalize the load on both pinions so that, in the long run, their duration is secured and the system availability
High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

The multimotor drives of heavy ball mills with open couplings of the peripheral tire and pinion gears are subjected to intensive wear and excessive angular and radial clearances. The different kinds of dynamical processes occurring in the drives of ball mills are investigated in [ 7 ] [ 8 ] .
This type of drive motor has come into limited use mostly outside of North America and with mills above 6000HP. This study began with a decision by The Monarch Cement Company to add a new cement finish mill to their plant in Humboldt, Kansas. The new mill would have a drive that was about four times larger than any of their present mills.
Problem 4: Vibration occurs when the motor speed reducer of the ball mill is started. Solution 4: Adjust the clearance between the two wheels to make the two shafts concentric. Fasten the coupling bolts symmetrically with the same torque. When the rotor is unbalanced, the rotor of the ball mill shall be pulled out for static balance. ...

Ball mill transport index control strategy. A simple ratio controller was implemented to regulate the solids content in the mill by manipulating the feed water. A calculated percent solid index is used to monitor the transport in the ball mill. A separate study was initiated to develop a measurement of this property (Bascur, 1985).
