SFS twin-screw feeders convey fluffy, cohesive and electrostatic powders steadily from 20 g to 120 kg/h — a linear rpm-to-feed curve ready for loss-in-weight control.
Highlights
Twin screws convey fluffy, cohesive and electrostatic APIs without bridging — linear screw rpm-to-grams curve for closed-loop control.
SFS-10 starts at lab micro-feeding; SFS-35 carries production lines.
Pairs with gravimetric control for continuous manufacturing.
Applications
- Continuous granulation lines
- Extruder downstream feeding
- Micro-dosing tracers and actives

FAQ
How do I feed poor-flowability API powder consistently?
Use twin-screw volumetric or loss-in-weight feeding: intermeshing screws convey material gently in a figure-eight barrel so it cannot compact. Output is linear, so a weighing system turns it into a precision feeder.
Can the feeder handle fluffy, low-bulk-density powders?
Yes — that is its design case. Fluffy, floc-like and electrostatic micronized powders are conveyed without bridging or compaction, from 20 g per batch upward.
Which SFS model fits my jet mill or granulator?
Sizing follows required feed rate: SFS-10 for lab mills, SFS-25 for pilot, SFS-35 for production. Tell us the downstream equipment and target rate for the match.
