For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
Aug 01, 2016· 2.2. 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 .While (i) is based on momentum balances, in (ii) a force–displacement 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 element.

The population balance concept has provided a useful framework for the description of the operating behavior of the ball mill. This approach finds expression in the so-called selection breakage function model for batch and continuous mills. This model produces veru good descriptions of the size distribution of the products from ball milling operations and the model is very useful for the ...

Ball Mill 2 3D model. A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.
