Feed Roll

Feed Roll Rotation

While standing on the right side of the machine the feed roll should spin clockwise.

Feed Roll Speed

The feed roll speed is designed to be variable. This allows you to specify the amount of product being fed to the rolls.

Wiring the Feed Roll

The feed roll is powered by either a one or two horsepower motor. This motor is powered and controlled from a variable frequency drive (VFD). The VFD should be interlocked to the main grinding motors such that it cannot be turned on unless the main motors are energized.

Flooding the Rolls

The operator must take care to avoid over-feeding the rolls. Over-feeding the rolls can cause the main motor amps to exceed recommended allowable amps and may result in obstructing product flow altogether, plugging the mill.

Gearbox Lubrication Guidelines

For general temperatures, the greasing guidelines and grease types recommended in the lubrication section are applicable. If, however, the mill environment temperature varies into the extreme hot or cold, a synthetic oil is preferable.  RMS recommends Lubriplate Syn Lube 220 L0975-057. The correct lubricant is important, as without the appropriate oil/grease, the gearbox could cease to function properly.
