This feature is available for both series and conventional granulators with auger screw. The RS provides optimal processing for continuous operation and to avoid shutdowns due to blocking. If an overload is detected by changes in amperage or speed, the motor stops and reverses to remove the part that caused the blockage and then turns forward again. This cycle can occur repeatedly until the rotor finally stops due to excessive temperature. n additional function is available to allow the automatic reversing to unclog teeth and mix the parts in the cutting. 5
