BALL MILL STARTING CURRENT Overview on the grinding mills and their dual pinion mill drives mill and two 24' x ' ball mills will be briefly discussed. ..... The typical directon line motors have a high starting current, larger than the rated motor current.
Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of meters and length of meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The lengthtodiameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and :1.
Maintain an adequate ball charge too low a ball charge is one of the leading causes of locked charge starts, especially in ball mills. Power draw should be maintained over 75% of mill rated power. A locked charge mitigating start procedure must be utilized if the mill is shut down for 15 minutes or longer.
