Oct 12, 2017· Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness.

The ball millliner and grinding medium are directly contacting with the ore particles which affects the movement state of the grinding media and the ore particles and affects the grinding effect. Among the influence of the ball mill lining on the grinding effect the most important one is the influence of the material and the liner's shape on grinding effect.
July 25, 2017 Liners. Grinding technology and ball mill conditions are two important factors that influence the performance of grinding steel ball. When we choose steel balls, both of the two factors should be taken into account, and then, the grinding system can achieve the ultimate goal with high yield, stable production and low consumption.

The grinding balls are widely used in cement works, they are often manufactured by the molding process, but the problem faced by major cement plants in Algeria is that these balls wear out quickly and broken. The objective of this work is to test wear resistance of grinding balls made by molding and grinding balls produced by forging.
Beneficiation ball mill has three influence factors in the grinding process with medium, including the ore properties, the structure of and the operation conditions of the machines.
Ball milling is an important technique in powder processing of ceramics. Although small balls as grinding medium in ball milling give fine powder, the grinding performance depends on many other milling conditions, such as combination of ball size, rotation speed and packing volume of balls.
