Exclusive Features

StopWatch Monitoring System

The StopWatch system helps reduce downtime by stopping the infeed and alerting the operator when un-grindable objects contact the rotor.

This patent-pending system reduces start-up amp surges by hydraulically spinning up the rotor before starting the main electric motor.

Adjustable Slab Ramp

This patented feature enables the operator to hydraulically raise or lower the height of the cutting anvil relative to the grinding rotor.
