Roll Crusher
For smaller angles of nip (finer feeds), the roll speed can be increased, thereby increasing the capacity. Peripheral speeds vary between about 1 m s −1 for small rolls, up to about 15 m s −1 for the largest sizes of 1,800 mm diameter upwards. The value of the coefficient of friction between a particle and moving rolls can be calculated from: () μ k = [1 + v 1 + 6 v] μ. where µ ...

Slitter Savvy: The Art of Winding Good Rolls
Roll hardness and profile are achieved by programmed nip control of the rider roll pressure and programmed torque control from the torque drum. Today, these winders usually are shaftless operation, run at high speeds, and are very productive. Their disadvantage is that they typically build hard rolls as the winding roll's weight produces the winding nip. This requires high rider roll pressure ...
