Large Ball Mill Scale

Large Ball Mill Scale

Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. this paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another.Ball mills play an important role in both energy consumption and metal wear in mineral processing plants. to maintain high operating efficiency, the material transportation inside the tumbling body has to be monitored in time. it is known that the vibration signal pattern varies corresponding to the operating state of the mill. besides the basic vibration signature from the rotary drum and.
