2. General Individual Mill Drive Concept

Each Roll in the mill tandem is driven individually

3. Strong Points in Choosing Individual Mill Drives

Increased overall power efficiency
Redundancy in the system in case one drive module fails
The right amount of torque at right roll all the time
Reduce:
- Floor space, less overhead crane width required
- No Tail Bar intermediate shafts, bearing supports, and coupling connections
- No axial forces on the tail bar acting on the gear unit output shaft
- The amount of spare parts, provided the drives are identical

4. Gear Unit Connection to the Mill

Hollow Shaft Shrink Disc with Torque Reaction Arm
Cylindrical Output Shaft, Rigid Flange Coupling, with Torque Reaction Arm
- Still maintaining “Shaft Mounted” principles but with the added extra ease to release the drive from the Mill.
We recommend to use Bevel Planetary setup to reduce overhung load on the output shaft induced by the weight of the electro motor.
