In this context, modeling of full-scale continuous ball mills could provide significant insights and help process design (King, 2001). Ball milling, where balls hit and grind particles in a rotating horizontal tube, is reported to be an inefficient unit operation (von Seebach et al., 1996, Fuerstenau and Abouzeid, 2002).

The Continuous Ball Mill is a type of grinder used to grind and blend materials. It works on the principle of impact and attrition. The Continue Ball Mill is divided in three main components. The vibratory feeder, ball mill and collector hopper. To manage the throughput and flow the machine can be set under a specific angle and has adjustable rpm.
