Double-Screw Dosing Feeder

Double-Screw Dosing Feeder

Industrial Twin-Screw Volumetric Feeder for Controlled Material Dosing
The Double-Screw Dosing Feeder is designed for controlled and uniform feeding of polymer raw materials into an extruder.
Its primary function is to deliver material in accurately controlled volumes, ensuring consistent and stable feeding during the extrusion process.

The feeding system consists of a stainless steel hopper, two feeding screws, and a gear motor.
The rotating screws transport measured volumes of material from the hopper to the extruder inlet, providing continuous and controlled material dosing.
The feeder can be integrated into various extrusion systems where precise volumetric material feeding is required.
