Description
Motan's single screw feeder CD 70 S is ideally suited for
dosing pellets, granulates, free flowing regrinds and flakes
in continuous and batching processes.
It can be controlled gravimetrically or volumetrically. The
compact, modular design gives the operator the flexibility to
meet changing process requirements. Feed rates range
from 1 - 3180 l/h (0.04 - 112 ft³/h). The specially formed
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 feed screw
removal from the rear.
