Screw Refeeding System (Screw Conveyor)
The Screw Conveyor (Auger Conveyor) is a powder-specific conveying system designed to lift powders and feed them directly into packaging machines — particularly auger filler dosing systems on VFFS and premade bag lines. Using a dual-motor design with independent feeding motor and vibrating motor, it ensures smooth, consistent powder delivery with adjustable vibration frequency and amplitude to prevent bridging or blockages. The material bin is designed for easy separation, loading, and cleaning with a reversible spiral discharge screw for quick material changes. Suitable for coffee, milk powder, washing powder, grape powder, and other fine powder materials.

Engineering Advantages
Built for Demanding Production Lines
Dual Motor Independent Control
Separate feeding motor and vibrating motor with independent control — allowing precise adjustment of both powder feed rate and vibration intensity for different powder characteristics.
Adjustable Vibration System
Vibration frequency and amplitude of the material bin are independently adjustable — preventing powder bridging, clumping, or blockages during continuous production.
Reversible Spiral Discharge
Screw designed for reversible discharge — enabling fast, clean material changeover without residue, and the complete screw can be easily removed for cleaning.
Easy Load & Clean Design
Material bin is separated by design for easy loading, unloading, and cleaning — with a gate discharge on the feeding tube for quick material removal between production runs.
Reinforced Vibration Motor
Vibration motor is reinforced for reliable, long-term operation under continuous production demands — reducing maintenance frequency and improving overall machine uptime.
Customisable Discharge Height
Discharge port height is designed to customer requirements — enabling flexible integration with packaging machines of different heights and line configurations.

Frequently asked questions
Alpha Pack makes packaging simple — from machine selection and installation to training and after-sales support, we’re here to help every step of the way.
What types of products can the screw conveyor handle?
The screw conveyor is designed for fine powder and granular materials including milk powder, coffee, flour, washing powder, grape powder, food additives and pharmaceutical powders.
Which packaging machines is this conveyor compatible with?
The screw conveyor is designed to work alongside auger fillers and can be connected to VFFS machines, premade pouch machines and other powder packaging lines to form a complete automated production line.
How is bridging or powder blockage prevented?
The dual motor system includes a vibrating motor with independently adjustable frequency and amplitude — keeping powder flowing consistently and preventing bridging or blockages during continuous operation.
Can the discharge height be customised?
Yes. The discharge port height can be designed to customer requirements — allowing the conveyor to integrate with packaging machines of different heights without additional adapters or modifications.
