Advanced Screw Conveyor Solutions for Modern Industries
Elevate your material handling capabilities with our precision-engineered screw conveyors. Designed for continuous, dust-free transport and precise volumetric metering of plastic flakes, regrind, pellets, and bulk industrial materials.
Unlock Efficiency and Reliability
Engineered for dependable, low-maintenance conveyance across continuous recycling and manufacturing operations.
Unmatched Material Versatility
Expertly handles diverse recycling feedstocks, from free-flowing PET flakes and regrind to stringy PE films and semi-solid wash slurries, across a wide spectrum of industrial sorting lines.
Optimized Throughput & Metering
Continuous material transport with minimal energy consumption. Seamless Variable Frequency Drive (VFD) integration enables precision dosing matching downstream extruder or granulator load.
Reduced Maintenance Overhead
Robust construction with wear-resistant spiral flights, isolated outboard pillow-block bearings, and PTFE gland packing seals translates to lower upkeep costs and prolonged operating life.
The Mechanics of Material Movement
At the heart of each screw conveyor is a precision-engineered helical screw blade (auger) rotating within a stationary trough or tubular housing to propel material continuously from infeed to discharge.
Uniform Infeed
Bulk solids or flakes enter via hopper directly into the flighted spiral intake, ensuring steady volumetric fill.
Axial Thrust
As the helical flight turns, trough wall friction prevents co-rotation, smoothly advancing material along the axis.
Metered Incline
Variable speed drive regulates throughput while engineered flight pitch prevents rollback on inclines up to 45 degrees.
Clean Discharge
Material exits through the drop nozzle directly into extruders, granulators, wash tanks, or storage bins without spillage.
Diverse Conveyor Designs for Specific Needs
Our screw conveyors are engineered in four primary configurations to match the specific physical behavior of your material stream—whether transferring dry regrind horizontally, elevating wet flakes, or moving tangle-prone films.
Horizontal Screw Conveyors
The workhorse configuration for transferring bulk solids, flakes, and regrind horizontally or at slight angles (0°–10°) between adjacent machines or beneath discharge silos.
Vertical Screw Conveyors
Compact vertical lift (up to 90°) for elevating pellets, granules, and dry flakes into elevated silos, storage hoppers, and compounding extruders within minimal floor space.
Inclined Screw Conveyors
Engineered for 10° to 45° elevation from low-level crusher outlets or wash tanks up to downstream dryers and granulators, equipped with anti-rollback screw flight geometry.
Shaftless Screw Conveyors
Coreless spiral design running on low-friction wear liners. The industry standard for handling tangle-prone plastic film, woven sacks, fiber, and sticky wet sludge without shaft wrapping.
All models feature high stability and wear-resistant spirals. Customization options for screw diameter (from compact to large-scale) and material construction are available to precisely meet your conveyance requirements and spatial constraints.
Engineered for Plastics Recycling & Specialized Bulk Handling
Unlike generic bulk conveyors, Energycle screw conveyors are purpose-built to solve specific challenges in plastics recycling and solid waste processing—preventing lightweight film wrapping, dewatering washed flakes, resisting abrasive regrind wear, and ensuring surge-free extruder feeding.
PE/PP Film & Woven Sack Scrap
Equipped with heavy-duty Shaftless (Centerless) Spirals engineered specifically for light, stringy agricultural film, post-consumer stretch wrap, and shredded woven bags. Eliminates the central shaft to completely eliminate filament wrapping and motor tripping.
Anti-Tangle ShaftlessPET Flakes & Rigid Plastic Regrind
Enclosed, dust-tight transfer of washed PET bottle flakes, HDPE regrind, and PP chips. Baffled U-troughs prevent airborne flake loss while inverter-controlled metering ensures consistent, surge-free feeding into granulators and pelletizing extruders.
Rigid Flake ConveyingWashing Line Dewatering & Wet Slurry Lift
Fabricated in SUS304/SUS316 stainless steel with a bottom perforated wedge-wire drainage screen. Conveys wet plastic flakes out of sink-float tanks and friction washers, pre-draining up to 70% of surface water back to the water treatment system during transport.
Drainage & DewateringExtruder, Granulator & Silo Metering Feed
Installed beneath storage silos, surge bins, and drying hoppers for precise volumetric dosing. Integrated with Variable Frequency Drives (VFD) for closed-loop speed regulation matching downstream compounding or granulator motor current.
Precision DosingE-Waste & Abrasive Engineering Plastics
Reinforced with NM400 / Hardox wear-resistant alloy spiral flights. Built to withstand aggressive friction from glass-filled PA/PBT, electronic shredder residues (ABS/PC), fine tramp metals, and mineral-loaded compounds without premature edge erosion.
High-Wear ResistanceIndustrial Sludge, Biomass & Solid Waste
Heavy-duty tubular or trough conveyors for moving municipal dewatered sludge, wood sawdust, wood pellets, rubber crumb, and agricultural bulk materials with sealed containment that protects workers and plant hygiene.
Heavy Bulk SolidsEvery screw conveyor is custom-engineered around material bulk density (from 0.05 t/m³ light film to 1.2 t/m³ dense regrind), moisture content, and line throughput requirements. Contact our engineering team for material test trials and layout recommendations.

Frequently Asked Questions (FAQ)
A screw conveyor transports plastic flakes, pellets, and regrind between processing stages using a rotating helical auger inside an enclosed trough or tube. It provides controlled, continuous material flow essential for feeding granulators, shredders, friction washers, extruders, and storage silos.
Screw conveyors feature a fully enclosed dust-tight design that prevents material spillage and contamination, can elevate materials at inclines up to 45 degrees within a compact footprint, and provide variable-speed metering. For wet or washed plastics, specialized perforated dewatering screws can also drain surface moisture during transport.
Our screw conveyors are engineered to handle a wide range of industrial materials, including plastic regrind, PET flakes, PE/PP film scraps (using shaftless spirals to prevent entanglement), granules, powders, wood chips, and industrial sludge.
Thanks to their robust design and minimal moving parts, maintenance requirements are minimal. Routine maintenance involves periodic inspection of external drive bearings, shaft packing seals, and screw flight wear. Maintenance access covers allow fast internal inspection and cleanout.
Yes. Every unit can be tailored to application demands, including screw diameter (150 mm to 400+ mm), pitch, total length, material of construction (carbon steel, SUS304, SUS316, or wear-resistant alloy), trough geometry (U-trough or tubular), and variable frequency drive (VFD) controls.
Standard configurations typically ship within 3 to 4 weeks, while custom-engineered systems (special alloys, custom lengths, or integrated dewatering screens) require 5 to 7 weeks depending on project specifications. Contact our engineering team for exact production schedules.
