23 Series Viper Granulators

23 Series Viper Granulator

Powerful, High-Capacity Granulators For Multiple Applications

Conair’s Viper Granulator, heavy-duty 23-Series granulators are designed for high throughput applications to provide exceptional and dedicated size reduction for blow molders, injection molders, extruders, and recyclers.

These industrial-strength granulators feature two styles of cutting chamber geometry from super tangential to tangential, allowing you to process virtually any kind of scrap.

Easy pre-adjustment of the gap between rotor and fixed bed knives results in increased throughputs and high-quality, uniform regrind.

Now standard with the “SG” (Smart Granulator) HMI touch screen control.

Hardened cutting chamber

The hardened cutting chamber provides greater resistance to wear.

Direct, safe and easy access to machine core

Conair’s innovative 23-Series tilt-back hopper and cutting chamber features a drop-down screen cradle and removable discharge bin. Complete rotor access greatly simplifies clean out and blade maintenance saving you time and money. Integral safety interlocks prevent accidental operation during service or clean out.

Greater screen area equals higher throughput with fewer fines

Increased rotor and screen contact area reduces heat generation and minimizes fines for best-in-class throughput of higher quality regrind.
