Working principle of rod mill. Rod mills run along the outside gear. Materials spirally and evenly enter the crushing chamber along the input hollow axis by input devices. Steel rods of different specifications are installed in the crushing chamber. When the frame rotates, centrifugal force is produced.

The working principle of ball mill and rod mill machine is similar, too. That is, the cylinder drives the movement of the grinding medium (lifting the grinding medium to a certain height then dropping). Under the action of centrifugal force and friction, the material is impacted and ground to required size, so as to realize the operation of ...

Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.

The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill, resulting in selective grinding carried out on the largest particle sizes. This results in a minimum production of extreme fines or slimes and more effective grinding work as compared with a ball mill.
