Feeder

Loss-in-Weight Feeder

Loss-in-weight Feeder, the accurate control of the extruder screw and Haul-Off, to ensure the extrusion products (thickness / weight per meter) is stable and reliable.

Feeder

Multi-Component Loss-in-weight Feeder

Doser-E is Economical version from D-Doser, controls the speed of the extruder by installing sensors at the bottom of the loss-in-weight barrel, continuously measuring the weight of the bucket, and combining a high-precision Line speed control system.

Feeder

Multi-Component Continuous Loss-in-weight Feeder

Multi-Component Continuous Loss-in-weight Feeder provides stable and high-precision raw material ratio and extrusion thickness/meter weight control solutions. The accurate control of extrusion traction ensures the uniformity of the thickness/meter weight of the extruded product; the high-precision proportioning (0.05%) ensures the accurate proportioning of the material types and uniform mixing.

D-Batch

D-Blender

D-Blender, using modular design, combined with high-speed pneumatic components, as well as high-sensitivity load cell, the system calculates dosing according to the percentage of each component. The minimum proportion accuracy is 0.1% and the error is 0.02%.

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.

Advantages of Dosing & Mixing

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 about feeders

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%.

What is the difference between the Ultimate and Economical models?

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