Single Screw Feeder NS70 Series

Orbetron feeders have been designed to grant a wide range of flexibility for different bulk solid materials and throughput ranges.

The single screw feeder NS70 is suitable for feeding granules, pellets, free-flowing regrinds, and flakes in continuous and batching processes.

Feeders can be controlled gravimetrically or volumetrically. The compact, modular design allows the operator the flexibility to meet changing process requirements. Feed rates range from (1-3180 l/h) (.03-112 cuft/h). The efficient design of the feed hopper yields a large screw intake length and ensures no dead zones in material flow. Quick material changes are ensured through the bottom cleanout and feeds crew quick removal from the rear.
