3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.

The working principle of a ball mill is based on the premise of impact and attrition. The rotation of the shell lifts the grinding media and then releases it to impact the feed material. This results in smaller particles of the ore particles. On the other hand, this process continues until the size of the ore particles reaches the desired size.
