Particle j~ows in a 5 m diameter ball mill are presentecL The charge behaviour, torque and power draw are analysed for a range of rotation rates from 50 to 130% of the critical spee~ Sensitivity of the results to the choice of friction and restitution coefficients and to the particle size distribution are examined.

Ball mill machine has always been the main grinding equipment in wet cement production. In the early years, the rod mill was first used in cement raw meal grinding, which increased the output of the grinding section by 31%, saved energy by 27%, and reduced the consumption of grinding media by 47%.

The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling.

Fig. 2 shows the variation of the average torque and power with mill speed for the ball mill described above with a fill level of 50%. The torque increases slowly until the peak is attained around N=80%.As the amount of cataracting increases, the balance of the charge improves and the torque required to maintain the asymmetric charge position declines steadily.
