The main difference between a rod mill and a ball mill is the grinding medium. Rod mills use long steel rods as the grinding medium, while ball mills use steel balls. Additionally, rod mills are better suited to handling larger feed sizes, and they create a more uniform particle size distribution than ball mills.
The difference on grinding medium is the main difference between the ball mill and rod mill. There is point-to-point contact between the ball mill with the steel ball, while there is line-to-line between the rod mill and steel rod. So, the working characteristics of the ball mill and rod mill are different. 4.
