12 Series Viper Granulators

12 Series Viper Granulator

Configurable Cutting Chamber For Multiple Applications

The innovative and adaptable hardened cutting chamber on the Conair Viper Granulator 12-Series granulators allows these granulators to be configured with different cutting chamber geometries to meet specific application requirements.

These quiet, heavy-duty plastic granulators feature two styles of cutting chamber geometry from super tangential to tangential, accommodating virtually everything from large bulky parts to heavy-wall profiles, sheets to sprues and runners. The result is increased throughput, greater efficiency and a more consistent and uniform regrind. Now available with an optional “SG” (Smart Granulator) HMI touch screen control.

Hardened cutting chamber

The hardened cutting chamber provides greater resistance to wear.

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.

Pre-Adjustable knives with scissor-cutting

Provides the ultimate in blade changes. The scissor-cutting knives are pre-set in the included knife setting fixture decreasing the time it takes to replace knives while improving safety and delivering the highest quality regrind.
