The Operating Principle Of The Ball Mill Waterfall mode motion speed mode with flying of grinding balls picture 1 grinding bodies in cascade a mixed b and waterfall c mill operation modes cascade mode motion of grinding balls carried out at low drum speed at startup of a mill the grinding material rotated by a certain angle and grinding balls start to move by closed path Page 1 Ball Milling Theory The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile which is known in the industry as the angle of break this angle can be between 40 to 65 degrees as measured from the horizontal if the angle is too shallow the media will not cascade much from one end to the other Amit 135 Lesson 7 Ball Mills Circuits Mining Mill For overflow ball mills the charge should not exceed 45 of the mill volume for grate discharge mills the charge should occupy about 50 of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge he and the radius of the mill r ie How To Size A Ball Mill Design Calculator Formula a total apparent volumetric charge filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume inside liners b overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge causing the total charge filling level to
