(1) The speed of ball mill. The speed of ball mill directly affects the motion state of steel balls and ores in the ball mill. When the speed is too slow, the steel balls and ore will slide down without rising high, and the crushing effect will be small; when the speed is too fast, the grinding medium will attach to the inner wall of the ball ...

To illustrate how grinding conditions can affect ball mill efficiency, the batch grinding model will be used to model closed-circuit ball milling of the soda-lime glass. For this model, the size range of a particulate assembly in a batch mill is divided into size intervals with a maximum size X 1 above and a minimum size X n+1.

Apart from these cost factors, one of the major unsolved problems in the optimal design of ball mills concerns the equilibrium media size distribution in the mill, which is determined by the rate at which make-up media is added to the mill, as well as the rate at which these grinding media are consumed (Austin and Klimpel, 1985). Reliable ...

2. Particle size of materials to be grinded. The particle size of the feed material is the main factor affecting the output of the rod mill. If the particle size is relatively large, more large balls must be added in one bin to break the material, which to a certain extent will increase the crushing effect, resulting in extremely unreasonable ...
