The ball mill has the unique advantage of "the particle shape is approximately spherical, which is conducive to the calcination of raw meal and the hydration and hardening of cement", which is the main reason why clinker mills still use ball mills. 4. Grinding process In the ball mill, the material is mainly crushed by impact and friction.
