wear in grinding mill

  • Grinding Media Engineered Mills Inc.

    The performance in all media mills is dependent on using the correct media type size and mill loading. New high performance beads have not only improved mill efficiency but also reduced wear on the beads and equipment. This along with long life easily justify the higher costs associated with these higher performance beads.
