Scaleup of mills is critical to the design and operation of industrial grinding circuits. This paper presented a scaleup model based on the discrete element method (DEM) simulation to predict the performance of tumbling ball mills. The mills of different sizes partially filled with steel balls and ground particles were operated at different loading and speeds.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

The MODSIM® ball mill model is an encapsulation of the scaleup procedure by Austin et al. (1984). It is used when the selection function and breakage function parameters have been determined from laboratory batch tests. In addition to this, the dimensions of the fullscale mill should be available. This is indeed the case in the present work.
