General work input function for sizing grinding ball mills

Nov 01, 2002Equations for power draft, capacity and work input for predicting the performance of industrial grinding mills are derived based on torque measurements using a laboratory instrumented mill. These derivations are based on mechanical principles and on the first-order kinetics of the grinding process. Rittinger's, Kick's and Bond's laws express work input as work index (Wi) times a particle

THE EFFECT OF BALL MILL OPERATING PARAMETERS ON

Later work done by Hukki (1975) attempted to show the validity of each theory within a certain particle size range. This study illustrated that Kicks law was applicable in the crushing range (above 1 cm in diameter) . Bond's theory was more suited to the particle size ranges involved in conventional ball and rod mill grinding (5 to 250 mm).
