Understanding the mechanism: How does a ball mill work?
Working Principle of a Ball Mill. The working principle of a ball mill is based on the rotation of the drum, which causes the grinding media to fall onto the material to be ground. The force of impact breaks the material into smaller particles, while the friction between the balls and the material causes further grinding and refinement. The ...
