  • Achievement of High Energy Efficiency in Grinding Mills

    2018-2-20 · SAG Mill Ball Charge The SAG mill was simulated to require a 10-12 ball charge with a top size of 125mm. During the commissioning phase no balls were required to be added to the SAG mill to achieve the target throughput of 575tph. This allows for great flexibility in the future and significant security for the future.

  • High Efficiency vs. High Feed Milling Which is More

    2018-11-2 · High-efficiency milling is based on the "radial chip thinning" theory that s been around for a long time. The basic idea is to keep the tool cutting at an ideal chip load. To increase the metal removal rate the stepover is substantially reduced from the typical 50 of tool diameter but the feed rate is increased in order to maintain the
