converting sag mill

Last week, the commissioning of the variable speed upgrade for the SAG mill of PanAust's Ban Houayxai Gold-Silver Operation in Laos was completed. Existing mines can now easily upgrade their processes by converting fixed speed mills into modern variable speed mills. The variable speed operation improves the efficiency in grinding process, reducing the …

Our Roller Mill Equipment. Automatic's industrial grain roller mills produce precise particle size every time, even when it comes to high volume grain processing – as much as 15,000 bushels an hour for our hardest-working, high-capacity models. Parallel, corrugated rolls uniformly process corn and other grains to exactly the right size.
