D-FEEDER
Screw Feeder
Screw feeder (D-feeder) series products adopt cascade feedforward control technology, combined with customized control system to comprehensively solve the problems of poor anti-interference performance, slow calculation speed, and easy replacement.
Our Advantages
Feeding technology must be carefully designed to avoid false sensing caused by capacitive sensors and uneven mixing caused by dead zones in the raw material mixing. Difini's feeders are market leaders in durability, and some of our systems have been known to operate continuously for over 25 years!

FAQs
What is the accuracy of the DEFINITI feeder?

Our loss-in-weight feeders achieve accuracy of ±0.3% to ±0.5%, while the volumetric series achieves ±1%. This is ensured through three key factors: first, the use of high-precision sensors from Siemens/Schneider; second, proprietary algorithm software for real-time compensation; and third, pre-shipment calibration testing of materials in a temperature-controlled laboratory.

What is the difference between the Ultimate and Economical models?

The Ultimate model is the highest precision model, with a precision of ±0.3%.
