With this new type of roller suspension, the rollers can be swung out of the mill in a controlled way – for ease of replacing the one-part grinding roller tires. The segmented wear parts of the grinding table are replaced, using a lifting device and the maintenance drive. Moreover, the rollers can be swung out separately.
The vertical forces are applied downwards by the roller and get compensated by the rotating grinding table. The forces act at several points around the circular line of the track.
