For the treatment of ore with large hardness and coarse grain size, it is necessary to have a large impact force, and it is necessary to install a steel ball with a larger size; the soft ore of the treated ore is smaller in size, and the finer particle size is required to be ground. Load a smaller size steel ball. The ball mill on the production site is loaded with balls of various spherical diameters, and the materials composed of different sizes of ore are processed according to a certain proportion. In theory, only by ensuring that a certain proportion of the balls can be adapted to the particle size composition of the material to be ground can a good grinding effect be obtained. The ratio of steel balls is a relatively complicated technical problem. Therefore, the production plant must be based on actual conditions, after a long-term investigation and research to find a reasonable ratio of loading. Table 5 below lists the empirical figures for the relationship between the ball diameter and the ore size, which can be used as a reference: Table 5 Relationship between spherical diameter and grain size Ball diameter (mm) 120 100 90 80 70 60 50 40 (mm) Pre solder Brass Fittings's solder ring is as smooth as yorkshire and it is real no lead according to Rohs,pre solder brass fittings,solder ring brass fittings,pegler solder ring brass fittings,connex solder ring brass fittings,SR brass fittings,solder ring brass pipe fittings presolder brass fittings,solder ring brass fittings,pegler solder ring brass fittings,connex solder ring brass fittings,SR brass fittings,solder ring brass pipe fittings Taizhou Runde Company , https://www.nerausmotor.com

Why do steel balls have to be loaded into the ball mill in a certain proportion by size?
The size of the steel ball depends on the physical and mechanical properties of the ore and the ore particle size composition.
