The main difference between ball mills and roller mills is the way in which the material is ground. In a ball mill, the material is ground by steel or ceramic balls, while in roller mills, the material is crushed between two rotating rollers. This leads to differences in the particle size distribution, energy consumption, and maintenance ...
