model to ball mill grinding. However, the same models could not be extended to semi autogenous grinding. Simply carrying out pilot scale SAG grinding is a very tedious task. At this time, the discrete element method appeared on the scene. DEM helps in simulating a number of features of SAG mills and AG mills, not to mention balls mill as well.

Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b. The size, density, and number of the balls. c. The nature of the balls (hardness of the grinding material)

Ball mills are widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, and the like.

Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

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. At a certain height, it will automatically fall and impact ...
