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.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

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).

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.

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.
