A.I.S. Screw & Auger Conveyors are engineered for efficient, controlled transport of powders, granules, flakes, and semi-free-flowing bulk materials. Designed for durability, consistency, and seamless system integration, AIS conveyors support both continuous and batch processes across a wide range of industries.
What sets AIS apart is the availability of Easy-Clean and sanitary conveyor designs, reducing downtime, simplifying validation, and keeping production moving—without turning cleaning into a weekend hobby.
What Are Screw & Auger Conveyors?
Screw (or auger) conveyors move bulk material using a rotating helical screw contained within a trough or tube. AIS designs these systems to deliver:
• Consistent material flow
• Controlled feed rates
• Minimal dust generation
• Compact layouts for tight plant spaces
• Reliable operation across varying material properties
They are commonly used to transfer material between bag dump stations, bulk bag systems, bins, silos, mixers, mills, and packaging equipment.
AIS Conveyor Design Capabilities
AIS screw and auger conveyors are engineered to match material behavior and process requirements—not generic assumptions.
Available configurations include:
• Horizontal, inclined, or vertical conveyors
• Tubular or U-trough designs
• Variable pitch screws for controlled feeding
• Flooded or metered discharge configurations
• Shafted or shaftless designs (application-dependent)
Each conveyor is sized based on bulk density, particle size, moisture sensitivity, abrasiveness, and required throughput.
Easy-Clean Conveyor Options (Where AIS Shines)
Cleaning downtime kills productivity. AIS Easy-Clean conveyor designs attack that problem directly.
Available Easy-Clean features include:
• Tool-less removable covers
• Quick-release trough clamps
• Hinged or split trough designs
• Pull-out screw assemblies
• Open-frame conveyor construction
• Smooth, crevice-free internal surfaces
These options dramatically reduce cleaning time, simplify inspection, and support fast changeovers—especially critical in food, pharmaceutical, and nutraceutical applications.
Sanitary & Hygienic Conveyor Designs
For regulated and washdown environments, AIS offers full sanitary conveyor solutions:
• 304 / 316 / 316L stainless steel construction
• Polished product-contact surfaces
• FDA-compliant seals and gaskets
• Washdown-ready motors and gearboxes
• CIP-compatible designs (application-specific)
Sanitary designs are ideal for allergen control, product changeover, and GMP-driven production environments.
Flexible & Rigid Screw Conveyor Options
AIS offers both rigid and flexible conveying solutions:
Rigid Screw Conveyors
Ideal for precise feeding, high throughput, and fixed routing between process steps.
Flexible Screw Conveyors
Used for routing around obstacles, feeding packaging machines, or gentle handling of fragile materials.
Both designs are engineered for predictable flow and easy maintenance.
Integration with Bulk Handling Systems
AIS screw and auger conveyors integrate seamlessly with:
• Bag dump stations
• Bulk bag unloaders and loaders
• Storage bins and silos
• Rotary valves and airlocks
• Mixers, mills, and reactors
Discharge interfaces, seals, and transitions are engineered to maintain dust control and system efficiency.
ATEX & NFPA Compliance for Hazardous Areas
For combustible dusts and classified environments, AIS conveyors can be designed in accordance with:
• ATEX Zones 20, 21, and 22
• NFPA standards including NFPA 652, 654, and 61
Available safety features include:
• Explosion-proof motors and electrical components
• Grounding and bonding provisions
• Anti-static components
• Dust-tight housings and covers
These designs support safe conveying without compromising cleanability or performance.
Materials Commonly Conveyed
AIS screw and auger conveyors handle a wide range of materials, including:
Food powders and ingredients
Nutraceutical and supplement blends
Pharmaceutical powders and APIs
Chemical powders and additives
Plastics resins and compounds
Battery and energy materials
Minerals, pigments, and fillers
If it needs to move cleanly and predictably, this is the workhorse.
Why AIS?
AIS screw and auger conveyors are engineered as process components, not just transfer devices. By combining robust mechanical design with Easy-Clean and sanitary options, AIS helps manufacturers reduce downtime, simplify compliance, and keep production flowing.
When cleaning is faster, changeovers are easier, and conveying just works—everyone downstream wins.
