For example, the comminution process of cement clinker followed the first-order grinding kinetics with the balls and rod media. Meanwhile, the grinding rate of the rod mill was higher than the ball mill [22]. The equivalent granule size declined while its specific surface area increased gradually with grinding time [23].

Ball Mill. The ball mill's basic concept dates back to prehistoric times when it was used to grind flint for pottery. A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell.

The ball mill liners are located on the inner surface of the ball mill barrel, which protects the barrel from the direct impact and friction of the grinding media and the material. The ball mill liners' material and shape are different base on requirements. When the grinding media contacts different shapes of ball mill liners, the movement state will …
