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 ...

Mechanical milling is a promising route for production of submicron and nano sized silicon powders, but it is challenging to predict and control the product properties. In this study a metallurgical grade silicon quality was milled in a planetary ball mill and the properties of the powder were investigated as a function of grinding time, grinding bead size (20 mm, 2 mm, mm) and rotational ...

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
