As the diameter and length of mills increased sev

  • Mill (grinding) Wikipedia

    A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

  • SAG Mill Control: It Shouldnt be that Hard

    The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill, but not the weight of the mill itself. While many mills today are mounted on load cells, others employ bearing oil pressure as a proxy measurement of mill load.

  • Using Fuzzy Control to Optimize SAG Mill Production

    mill speed will help grind more rock. If the mill weight is dropping very quickly, then the speed should be decreased so as to maintain process stability.
