8 Rolling Mills Revamp: Roll Upgrades for Extreme Loads Figure 11: Roll neck assessment before upgrade: Maximum stress and fatigue life. Since the bearing cups are stationary in the chocks, only one part of the cup carries the rolling load at any given time. This part is called the 'load zone'. Roll neck bearing cups are marked on their ...
The bearing load capacity is large and the impact is large. The four-row cylindrical roller bearings are interchangeable. It is roughly the same as the four-row cylindrical roller bearing of wire and bar, but the size of the inner ring raceway is remained with the amount of grinding. The bearing clearance is the clearance after grinding.
8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.
