explored the spectrum of collisional energy in ball mills. The authors observed that the operational conditions of the mill signicantly changed the energy distribution over the load in the equipment. Silva et al. (2019) quantied the number and the intensity of the collisions in a dryer with inert bed, to dif-ferent speeds of bed rotation.

Principle of Ball Mill Operation. The ball mill operates by rotating a cylinder horizontally and partially filled with balls. The cylinder's rotation causes the balls to cascade and fall back into the mill, generating impact and friction against the material to be ground. The following are the key components of a ball mill: 1.
