The Auger Powder Filling Machine measures and dispenses dry powders using controlled servo-driven auger rotation. It handles volumetric dosing into bags, pouches, bottles, jars, and cans across manual, semi-automatic, and fully automated packaging lines. Standard filling range options include 1–10 g, 5–25 g, 10–50 g, 10–100 g, 25–150 g, and 50–500 g.
Operating Mechanism
Auger Screw Dosing
Rotating screw transfers powder from the hopper through the dosing tube into the target package.
Rotational Control
Fill weight correlates directly to total screw revolutions, shaft speed, and pitch dimensions.
Direct Discharge
Powder dispenses directly through the nozzle outlet to minimize residual dust and product degradation.

Powder Behavior Compatibility
Free-Flowing Powders
Granular spices, salt, and fine sugar flow under gravity into the auger flights without bridging.
Non-Free-Flowing Powders
Fine flour, cocoa, and starch require integrated agitator blades to prevent rat-holing in the hopper.
Variable Bulk Density Powders
Nutritional powders require variable-speed drive control to maintain uniform dosing volume.
Dosing Range Configurations
Micro Dosing (1–10 g / 5–25 g): Utilizes small-diameter high-precision machined augers for small sachets and vials.
Standard Dosing (10–50 g / 10–100 g): Standard production size for commercial retail pouches, cans, and jars.
Bulk Dosing (25–150 g / 50–500 g): Employs large-pitch augers and wider fill nozzles for volume packaging.

FAQ
Q: How is target fill weight adjusted during operation?
A: Adjustments are made directly on the PLC interface by changing the total rotational count or speed of the servo motor.
Q: What contact materials are available for corrosive or food products?
A: All product-contact parts are fabricated from AISI 304 stainless steel as standard, with AISI 316L available for corrosive chemical applications.
Q: Can the machine handle both free-flowing and non-free-flowing powders?
A: Yes, selecting the correct auger diameter along with an internal agitator blade prevents bridging and ensures consistent feeding for non-free-flowing materials.
Q: How are changing container opening sizes handled?
A: Discharge nozzles are interchangeable and selected based on the internal diameter of the container opening.
