The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: • Strong drying ability Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

The ring ball mill has a grinding ring (5) defining a grinding groove. Multiple grinding balls (6) are designed along a grinding groove for a grinding rotation and a pressure ring (7), which presses the grinding balls against the grinding groove. The pressure ring is assembled from multiple pressure segments (71,72) that are connected with each other in detachable manner.
The large ring gear is the main component of the ball mill, it needs to drive theentire barrel for a long time.
