Compatible. Reliable. Cost-Effective.
Our spiral augers offer seamless integration with key major flexible screw conveyor systems. Whether you’re upgrading existing equipment or specifying components for a new system, our augers deliver consistent, trouble-free performance. Each spiral auger is designed for easy installation and cost-effective operation, backed by competitive pricing and reasonable lead times, we provide exceptional value without compromising on quality, helping you keep your operations efficient and on budget.
Spiral Auger Types
To ensure optimal flow characteristics and material compatibility, we offer a selection of auger profiles, including round, flat and square.
Round – Performs best with granular materials such as sugar, salt, rice, and oats, although suitable for almost any application. The most versatile of our spiral auger range.
Flat – For use with extremely fine, light, and aerated powders. A slight increase in capacity is achieved with subsequently increased volume. Examples of suitable materials include powdered sugar, talcum powder, and pharmaceutical powders.
Square – For use with heavy and or abrasive materials. Materials suited to a square section include pigments, calcium oxide, and silicon carbide.
Designed for Performance Across All Industries
Our spiral augers are trusted across a wide range of industries for their exceptional durability, hygienic easy-clean design, and reliable powder handling performance. Here’s how they deliver value in each sector.
Food, Beverage & Confectionery – Our spiral augers are made from stainless steel, ideal for handling ingredients like flour, sugar, cocoa, spices, and grains. Their hygienic, easy-to-clean design meets food safety standards, helping to maintain product purity and reduce contamination risk.
Seasoning & Flavouring – Fine, aerated powders such as seasoning blends, powdered sauces, and flavour enhancers require consistent and gentle conveying. Flat-section spirals improve flow characteristics and maintain blend integrity, ensuring even distribution and minimal segregation.
Animal & Pet Food – Heavy-duty spiral augers are ideal for transferring dry kibble, powdered supplements, vitamins, and feed additives. Their robust build ensures smooth operation, even with high bulk-density or abrasive materials.
Environmental (Water Treatment & Flue-Gas Desulfurization) – Spiral augers are used to convey chemicals like hydrated lime, powdered activated carbon, and other treatment agents. Our square-section spirals are ideal for these dense or abrasive materials, ensuring longevity and reduced wear in demanding conditions.
Plastics – Our spiral augers are ideal for handling polymer powders, plastic pellets and flakes, colourants, and masterbatch materials. Their robust construction ensures long-lasting performance, suitable for abrasive and high-volume applications, they help reduce wear, minimise downtime, and keep production running efficiently.
Pharmaceutical – Precision and hygiene are critical. Our stainless steel spiral augers offer volumetric consistency and GMP-compliant materials for safe transport of fine powders like excipients, active pharmaceutical ingredients (APIs), and vitamins.
Nonwovens – Used for conveying binding agents, fibres, and powders in hygiene product manufacturing. Our gentle handling ensures material integrity without degradation or blockage in lightweight bulk solids.
Chemical – Our spiral augers are engineered to handle the rigorous demands of chemical processing. Whether you’re conveying pigments, silica, resins, or fine industrial powders, our augers offer exceptional resistance to corrosion and abrasion. Built from durable materials and heat-treated for added strength, they ensure reliable performance, reduced and longer service life, even in aggressive chemical environments.
