S Series Granulators

S Series Viper Granulator

Screenless Slow Speed Beside-the-Press Recycling

Compact S Series Granulators are ideally suited for metered robot or conveyor feed beside small injection molding machines.

This quiet, energy efficient granulator features a screenless cutter housing and ultra-low rotor speed to reduce sprues and runners to consistently sized granules, virtually free of fines and longs.

Multi-tooth rotor

Multi-tooth rotor cleanly reduces sprues and runners to consistent sized particles. Rotors with D2 teeth and cutting wheels can be re-sharpened. The automatic reversing option helps to clear obstructed material.

Easy portability

Large casters allow easy movement; the S Series conveniently services multiple presses. The small footprint accommodates tight spaces and the wide-mouth, flared in-feed hopper easily handles a range of robot or conveyor drops and sprue/runner sizes.

Quiet operation

The S Series low-speed rotor decreases noise levels with most materials to as low as 80 dbA and in some cases as low as 70 dbA, eliminating the need for sound enclosures.
