When it comes to powder filling machines, manufacturers face a key decision: invest in high-speed rotary powder filling systems or opt for a dual-head in-line auger filler. Both options are offered by AMS Filling Systems, a leading provider of reliable powder filling equipment.
The right choice depends on production volume, container type, budget, and long-term scalability. In this article, we’ll explore the features, benefits, and best use cases for each technology so you can make an informed decision.
What Is a High-Speed Rotary Powder Filling Machine?
A high-speed rotary powder filler uses a turret design where multiple stations fill containers simultaneously. AMS rotary models, such as the A-700, can be equipped with up to 36 filling heads and achieve speeds of up to 700 containers per minute.
Key Features and Benefits of Rotary Powder Fillers:
- High throughput capacity – ideal for large-scale production.
- Continuous or indexing motion – ensures smooth handling and minimal product spillage.
- Advanced container handling – tackles difficult shapes and settling requirements.
- Future-proof scalability – designed to accommodate growth in demand.
- Reduced product giveaway – consistent dosing accuracy at scale.
Best for: high-volume operations such as food, supplements, and chemical powders where output speed and consistency are top priorities.
What Is a Dual-Head In-Line Auger Filling Machine?
A dual-head in-line auger filler uses two filling stations mounted in sequence along a conveyor. AMS’s dual-head systems, like the A-500, are designed to double throughput compared to single-head fillers, while maintaining flexibility and precision.
Key Features and Benefits of Dual-Head In-Line Fillers:
- Two auger heads – boost production rates without the complexity of a rotary system.
- Bulk + dribble fill capabilities – deliver both speed and high accuracy.
- Compact footprint – requires less floor space than rotary machines.
- Lower initial investment – cost-effective option for mid-range production needs.
- Easy changeovers and maintenance – ideal for multiple SKUs and frequent adjustments.
Best for: medium-volume manufacturers in industries like cosmetics, nutraceuticals, and contract packaging that need flexibility and cost efficiency.

When to Choose Each Powder Filling Machine
Choose a High-Speed Rotary Powder Filler if:
- You need very high output (hundreds of containers per minute).
- You work with difficult containers or powders requiring settling.
- You want to future-proof production capacity as demand grows.
- Your budget and floor space can support a larger system.
Choose a Dual-Head In-Line Powder Filler if:
- Your production demand is moderate but growing.
- You require frequent product changeovers or SKU flexibility.
- You need a cost-effective solution with a smaller footprint.
- You’re a start-up, co-packer, or mid-size manufacturer balancing throughput and investment.
Real-World Applications
- Nutritional supplements: High-speed rotary fillers deliver the volume needed for protein powders and drink mixes.
- Cosmetics: Dual-head in-line systems handle multiple product types with precise dosing and fast changeovers.
- Food & beverage: Both systems excel, with rotary supporting large-scale runs and in-line providing versatility for specialty products.
Both rotary powder filling machines and dual-head in-line auger fillers offer unique advantages. The right choice comes down to production scale, flexibility needs, and budget.
- For high-volume, long-run operations, a high-speed rotary filler is the clear winner.
- For flexibility, cost efficiency, and mid-range throughput, a dual-head in-line filler may be the smarter investment.
