Contact modeling. The most critical ingredient in the model of a ball mill is the contact law. Contact models belong either to the (i) discrete or (ii) continuous approach [20].While (i) is based on momentum balances, in (ii) a forcedisplacement law is added to the equation of motion, as a combination of a spring in parallel with a damper, causing energy dissipation, plus a friction ...
