practical applications of tumbling and grinding mills

  • IN WET TUMBLING MILLSSMC Testing

    Data were collected from a wide range of wet industrial grinding mills to calibrate and verify the model. In total 76 data sets were generated covering the power draws of ball SAG and AG mills in the range 7 7900 kW. All threemodels were found to predict the power draw of the mills in the data base with a high degree of accuracy.

    Sep 22 2003 · The power draft and grinding efficiency of tumbling mills depend solely on the motion of the grinding charge and the ensuing ball collisions that utilize the input power to cause particle breakage. Power draw analysis was first attempted by Davis (1919) by considering the dynamics of the ball charge through individual ball paths and velocities.
