The roller hub is the core component of the vertical mill grinding roller assembly. The roller sleeve is fixed on the hub, and the hub is mounted on the roller shaft to form a grinding roller assembly. Generally, a tapered structure is adopted between the roller sleeve and the hub, which ensures the convenience of inspection and disassembly.
