A ball mill is a large equipment that grinds down the material fed into it to give a coarse end product with smaller particle sizes One of the primary applications of ball mills is in ore dressing Planetary ball mills on the other and are relatively much smaller and are used in labs to grind down samples into fine
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 very good descriptions of the size distribution of the products from ball milling operations and the
May 22 2019 The ball mill consists of a metal cylinder and a ball The working principle is that when the cylinder is rotated the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force
Computational techniques that have accompanied A ball mill is one kind of grinding machine and it is a This relationship was successfully used for the scale up of a rocking ball mill and the optimum design and operating conditions for the rocking ball mill could be estimated by the specific impact energy of the balls cal
