Mathematical model of ball wear in grinding mills …
Using a population balance approach, a general mathematical model is developed for the ball wear in rotary grinding mills. The first-order partial differential equation obtained is solved, using a zero-order kinetic as constitutive equation for the ball wear, obtaining the transient solution. The model prediction for the ball size distribution at steady state shows excellent agreement with experimental data obtained from three different industrial mills…
A mathematical model for simulating and …
A new mathematical model for grinding the ball part of a ball end mill is proposed. The complete process for manufacturing a ball end mill is formulated, including processes such as modeling the rake and clearance faces. The helical flute surface of the ball end mill is analytically calculated and verified by means of simulation and experiment. The study is summarized as follows:
A Mathematical Model for Predicting the Internal ...
Mathematical models, which link the external signals of ball mill with its internal parameters, were established to predict the internal parameters of ball mill. Experimental results showed that the mathematical models could directly predict the internal parameters of ball mill once the external signals were obtained. The tri-sensor measurement method and the mathematical models proposed in this stone provided a new way and solid basis for optimization and control of ball milling.

Mill (grinding) - Wikipedia
A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
