HGB-Series GRAVITROL® Weigh Hoppers

Check up to five results to perform an action.


Designed for use as part of the Gravitrol® system, the HGB Series Weigh Hopper incorporates engineering and design breakthroughs to help achieve the optimal result in extrusion: a uniform product within tolerance at the lowest possible manufacturing cost.

The Gravitrol® system gives you total control over your mono-extrusion or coextrusion processes. The system can be configured to control extruder rate by weight; layer percentages by weight; weight of extrudate by length; average thickness; and pipe or tube diameter.

The HGB Series Weigh Hopper is a central part of this system because it precisely monitors the amount of material consumed by the extruder. In effect, the extruder becomes a gravimetric metering device.

PCC's HGB mounts directly on the throat of your extruder, requiring no additional support. Standard hopper sizes control an extruder throughput at rates from 10 to 10,000 PPH. Higher-rate hoppers are available on special order.

The HGB Series' clear polycarbonate inspection/clean out door or sight glass allows visual inspection of hopper contents.

Each hopper has a PCC-designed and built Weigh Module which connects to the load cell and precisely measures the extruder's material consumption. This information is digitized on the hopper for fast, error-free and noise-immune communications with the central Gravitrol® computer. Four-point overload protection on the hopper protects the weighing system from damage due to accidental contact.
