Modelling The Specific Grinding Energy And Ball. Power draw of denver ball-mills in our previous work (stamboltzis and tsakalakis, 1993) we showed that the tumbling mills power draw p is proportional to the product d1835xl, where d is the internal mill diameter and l is the mill length..the bond (classic) method gives one ball-mill (d x l 3.05 m x 5.83 m) and operational conditions p 4.
