Flexible Screw Conveyors
For Efficient Bulk Material Handling
Key Benefits of Flexible screw conveyors
Versatile Bulk Material Handling – Efficiently conveys powders, pellets, flakes, granules, brittle materials, and more, making it ideal for applications in the food, pharmaceutical, plastics, chemical, and environmental industries.
Flexible Layout Options – Easily configured for horizontal, vertical, inclined, or complex routing around plant obstacles. Perfect for tight spaces and multiple discharge points.
Dust-Tight & Contamination-Free – UHMWPE tubing provides a sealed conveying path, maintaining hygiene and preventing product contamination or loss.
Gentle, Controlled Product Flow – Single-motor operation ensures smooth, low-impact transport, reducing product degradation and preserving mix integrity.
Corrosion & Chemical Resistance – Resistant to a wide range of chemicals, acids, and corrosive materials—ideal for harsh environments and aggressive substances like hydrated lime or silica.
Food-Safe and Non-Toxic – Constructed from physiologically safe UHMWPE, ensuring no harmful effects during contact with sensitive or edible products.
Certified for Safety – Manufactured using extrusion-grade materials compliant with EC and FDA food-contact standards, supporting GMP and HACCP processes.
Ultra-Smooth Internal Finish – Minimises material buildup, enhances cleanliness, and simplifies routine maintenance and washdown procedures.
Self-Lubricating Properties – Naturally low-friction surfaces promote clog-free material flow without the need for additional lubricants or coatings.
Cost-Effective & Energy Efficient – A compact, motor-efficient design and in-house component production help reduce overall operating costs while maintaining premium quality.
built to last flexible screw conveyors for reliable material handling
Our flexible screw conveyors are engineered for seamless integration into any production setup, whether fed from sack tip stations, storage hoppers, FIBC dischargers, or other material handling systems. The base system provides reliable material transfer, while optional enhancements such as agitation systems, easy-clean features, quick-release assemblies, and custom surface finishes (standard, crevice-free, or high polished) help reduce downtime, maximise hygiene, and boost productivity.
Manufactured for maximum durability, all steel components are made from either mild steel or stainless steel variants, with every element, including inlets, outlets, hoppers, lids, agitators, flanges, and drive shafts, designed to meet your specific process requirements. Other key components include –
Spiral auger – cut to length and available in a range of diameters and profiles (round, bevelled, or squared) to suit the material being conveyed.
Dust-tight UHMWPE outer tube – cut to length, available in multiple diameters, offering low friction, chemical resistance, and high wear durability.
OEM compatibility – both the spiral and tube are compatible with other brands of flexible screw conveyors, enabling easy integration into existing systems.
Agitation Systems for Consistent Flow of Problematic Materials
When you’re handling materials that resist movement, an effective agitation system becomes indispensable. Without it, build-up occurs, production slows, downtimes increase, and conveying efficiency suffers. With the right agitator in place, the material remains actively conditioned and continually disturbed, enabling smooth and reliable flow.
Although the typical solution is a contra-rotating agitator blade mechanism, other styles of agitation can be applied depending on the nature of the product. We assess the material’s flow properties carefully to select the optimum agitator style for your application.
For certain powders or granules that don’t respond to standard flow techniques, vibratory agitation may be used, though this is less common, since our independently-driven agitation systems provide precise control of rotation speed and material conditioning, ensuring excellent flow control even for challenging materials.
Common Flow Challenges –
Rat-holing – When the material forms a void or “channel” above the spiral auger or inside the hopper, constricting the flow and reducing conveying efficiency.
Bridging (or Arching) – When the powder or granules form a stable arch or bridge above the auger or hopper discharge point, preventing material from entering the conveying inlet.
Such challenges demonstrate why the right agitation technology makes all the difference. Trantec agitators deliver constant, dependable motion, keeping materials flowing freely, eliminating blockages, and ensuring your production line runs smoothly and efficiently.
flexible conveying across industries
Our complete flexible screw conveyor systems are trusted across a wide range of industries for their hygienic design, long-lasting durability, and versatile performance. Engineered for efficient, contamination-free handling of powders, granules, and flakes, they offer smooth, consistent flow with minimal maintenance, ideal for both light and heavy-duty applications.
In the food and beverage sector, our conveyors provide safe, reliable transport of ingredients such as flour, sugar, grains, and cocoa, preserving blend integrity even with fine, aerated materials like seasonings and additives. In chemical and environmental industries, they excel at handling aggressive substances like hydrated lime, silica, and other industrial powders, thanks to their exceptional chemical resistance.
Our systems also support high-volume processing in the plastics and nonwovens sectors, efficiently conveying pellets, fibres, and flakes while reducing blockages and equipment wear. Beyond these core applications, we supply flexible screw conveyors to a variety of other sectors, including pharmaceutical manufacturing, where GMP-compliant, contamination-free performance is essential, as well as water treatment, flue gas treatment, animal nutrition, and more.
