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 mills can be driving by medium voltage motors or wrap around motors, knows as Gearless Mill Drives (GMD). The grinding mills are manufacture using steel plate and some casting parts.
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.

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.
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.
