From grain to feed
Feeder Screw
The Feeder Screw delivers a steady, uniform flow of powders and granulates into the process. Fully stainless steel construction and optimized screw geometry ensure accurate dosing, even distribution, and long service life with low maintenance. Available in standard or heated versions, it supports consistent feed rates for stable pelleting and process efficiency.
- Uniform, consistent product flow
- Durable stainless-steel construction
- Low maintenance, long service life
