The Double Screw Powder Filling Machine is designed for large-weight powder packaging from 15 kg to 50 kg, combining high filling speed with reliable accuracy through a two-stage screw system. The main screw delivers the bulk material to ensure fast filling, while the VFD-controlled fine screw precisely adjusts the final weight without the need for servo motors. A dust-tight bag clamping system ensures clean, leak-free filling, and the height-adjustable non-powered roller conveyor accommodates different bag sizes. Built for industrial use, the machine offers stable performance, easy operation, and dependable results for demanding powder applications.
Dual-Screw Filling Concept
The twin auger filler operates with a dual-stage filling principle. A large auger performs high-speed bulk filling to reach the majority of the target weight, while a smaller auger completes fine filling for precise control. When integrated with a load cell, the system forms a closed-loop control, achieving high accuracy and efficiency. This design significantly reduces overfilling and improves consistency, making it ideal for high-value powder applications.
