As the rotation speed of the highspeed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is [49, 50]. The parameter setting of the ball mill is shown in Table 1.

In addition to steel balls, the wet ball mill also needs to add liquid to participate in grinding. Usually, the proportion is steel ball: material: water=4:2:1. The nature of different materials is different, so the actual steel ball, material, and water proportion will be adjusted, and determined by the experimental test. 4) Different application

The ball mill is a horizontal structure. When ball mill works, the rotation of grinding body drives the steel balls inside. The grinding media, steel balls, reach a high point and fall down. The compaction against each other grinds materials into powder. The product is discharged through the discharge grates.

Ball mills are filled up to 40% with steel balls (with 3080 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
