Whereas vibratory feeders are better for irregular product and those that would damage or be damaged by feed screws, screw feeders can handle certain products better, such as liquids and viscous or sticky slurries. If your product fits in neither or both categories, reach out and we’ll identify the best solution.
Bulk Feeders – 282 to 1,112 ft³/hr
The bulk feeder is ideal for lighter, more fluffy powdered products. Most popular for plastic film extrusion and compounding, it can directly fill large vessels or maintain load for smaller, downstream feeders. The system is designed to allow easy dismantling for cleaning and is available in steel for more abrasive applications.
Accuracy to spec.
Features:
- Internal Agitator (bottom-driven for balance)
- Double-wound helix feeder (maintains smooth feed at low speeds)
- Modular components (easily adaptable for different speeds and products)
- Tube-in-tube discharge minimizes wear
Options:
