  • Ball Mill Operation -Grinding Circuit Startup Shutdown

    The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.
