James Eagen Sons designs and fabricates auger-type conveyor screws up to 120 in ID and 65 ft long, forming sectional, helicoid, ribbon, or dual-start flights from heavy plate or strip. ± 1/16 in pitch tolerance and AWS-certified welds deliver smooth, reliable bulk-handling for abrasive, food-grade, or high-speed applications.

Finished rotating assemblies for bulk-material handling and metering—complete shafts with welded flighting, journals, keyways, and, when specified, couplings or drive flanges. Supplied as drop-in replacements or new builds for screw conveyors, feeders, mixers, pug mills, and reactors. Available in sectional or helicoid construction, carbon or stainless alloys, with optional hard-facing, dynamic balancing, and sanitary finishes.

Conveyor Screws / Auger Shafts

Auger shaft whose pitch is less than the flight outside diameter (typically 0.5 × OD).  Used for steep-incline conveying, metering, or gentle handling of powders that tend to aerate.

Short-Pitch Conveyor Screw

Flight pitch greater than the outside diameter (1.0 – 2.0 × OD).  Yields higher capacity per revolution and lower power draw with free-flowing bulk solids.

Long-Pitch Conveyor Screw

Pitch changes along the screw length (e.g., 0.5 × OD at intake to 1.0 × OD at discharge) to accelerate flow, prevent surging, or de-aerate material.

Variable-Pitch Conveyor Screw

Flight outside diameter tapers from one end to the other to equalize draw-down from bins or reduce start-up torque on long screws.

Tapered-Flight Conveyor Screw

Flights have radial notches that break up cohesive or sticky material and reduce wall buildup in the trough.

Cut-Flight Conveyor Screw

Notched flights with tabs bent 90°–120° to act as paddles—adds gentle mixing or aeration while conveying.

Cut-and-Folded Flight Conveyor Screw

Two identical flights 180 ° apart (double-flight) that double feed rate per rev and deliver smoother, pulse-free discharge.

Dual-Start Conveyor Screw

Conveyor screw that replaces continuous helical flights with discrete, radial paddles welded to a center shaft. Tunable paddle angle/spacing enables forward, reverse, or neutral net conveying while providing agitation, mixing, and conditioning of cohesive, sticky, or fragile bulk solids. Open geometry mitigates buildup versus full-flight designs and can be configured for gentle handling or aggressive de-agglomeration.

Paddle Conveyor Screw

Custom Screw Conveyors & Feedscrews

CNC-nested plate blanks are plasma-cut and press-formed into 360° sectional flights as large as 150 in OD and 2 in thick. Presses exceeding 1 000 kN form short, long, or variable-pitch segments in carbon, stainless, abrasion-resistant, or nickel alloys. Tight ±0.25 mm blank accuracy and fixtured welding produce concentric flights ready for shaft assembly or loose shipment for on-site fit-up.

A forming process that plasma-cuts flat plate blanks and press-forms each into a 360° helical segment (sectional flight).  Enables very large diameters, thick plate, and exotic alloys unsuitable for continuous coiling.  Flights are subsequently welded to pipes/shafts or shipped loose for on-site assembly.

Sectional-Flight Fabrication

Plasma Cutting involves using a plasma torch to cut through various types of metal, effective for both thick and thin materials.

Plasma Cutting

Cold or hot pressing of pre-cut plate blanks around a forming mandrel to create 360 ° helical segments for large-diameter or thick-plate screws.

Sectional-Flight Press-Forming

CNC plasma or laser cutting of mixing slots, dewatering holes, or aeration patterns into flight blanks prior to forming.

Notched & Perforated Flight Fabrication

Fixtured fillet or plug welding of sectional flights to pipe or solid shafts; includes straightening and concentricity checks.

Flight-to-Shaft Sub-Assembly Welding

Special press-forming route for plate >25 mm thick or wear-resistant steels (AR400, Hardox) requiring elevated forming forces and controlled heat input.

Heavy-Gauge Sectional Flight Forming

Sectional ribbon flights whose support legs are cut and formed integrally from the same plate blank, then bent inward and welded to the shaft or hubs. The spacer-less, open-core geometry improves cleanability and reduces material buildup versus spacer-bar constructions while maintaining ribbon stiffness and concentricity for mixing, conditioning, or gentle conveying of cohesive or fragile bulk solids.

Integral-Leg Ribbon Flights

Sectional Flight Fabrication

Continuous helicoid flights are cold-formed from strip bar on five dedicated winders. Post-forming spirals can be cut to specific lengths or shipped as Mill Length Spirals.

Cold-forming process that continuously coils bar or strip into a seamless helix (helicoid flight).  Provides high throughput and minimal scrap for small- to mid-diameter screws or long production runs, with options for tapered OD, variable pitch, and spliced or hybrid constructions.

Helicoid-Flight Fabrication

Continuous cold-rolling of bar or strip into a seamless helix—economical for high-volume screws up to 12 mm thick.

Helicoid Flight Rolling / Cold-Forming

CNC-controlled shearing or plasma cutting of continuous helicoid coils into precise screw sections ready for shaft welding.

Helicoid Flight Cut-to-Length

Continuous TIG/MIG welding of helicoid flighting to pipe or tube; includes straightening and ISO G6.3 dynamic balancing.

Helicoid Flight-to-Pipe Welding

Splicing two helicoid sections or welding a helicoid run to sectional segments to overcome length limits or provide mixed geometries.

Flight Splicing & Hybrid Helicoid-Sectional Welding

Helicoid Flight Fabrication

Fabrication of single-, double-, and paddle-style mixing screws for ribbon blenders, paddle mixers, and agitator troughs. Flights and paddles are CNC-cut, press-formed or helicoid-rolled, then fixtured and welded to precision-machined shafts. Final assemblies can be dynamically balanced, polished to sanitary standards if required, and delivered ready for drop-in installation.

Specialized auger assemblies featuring ribbon, paddle, or cut-and-folded flights for convective or high-shear mixing inside ribbon blenders, paddle mixers, and reactors. Designs include single- and double-concentric ribbons, lug-style paddles, and hybrid ribbon-paddle combinations. Delivered dynamically balanced, heat-treated (if applicable), and sized for clearances of 0.125 in (3 mm) or tighter.

Ribbon & Blender Screws

Auger with one continuous ribbon flight used for gentle radial mixing and folding of dry blends or fragile particulates.

Single-Ribbon Mixer Screw

Concentric inner and outer ribbons of opposite hand for convective mixing—moves material radially and axially for faster blend times.

Double-Ribbon Mixer Screw

Shaft with radial paddles (single or staggered) for high-shear mixing, de-agglomeration, or crystallizer agitation.

Paddle Mixer Shaft

Ribbon flight with periodic cut-and-bent tabs that create localized paddling—hybrid between ribbon and paddle screws.

Cut-and-Folded Ribbon Screw

Turn-key build and ISO-grade dynamic balancing of complex mixer shafts—includes end hubs, spacer bars, and bearing journals.

Powder Coating is a dry finishing process where a powder material is applied to a metal surface, then cured under heat to form a hard, protective layer. This coating is durable, corrosion-resistant, and available in many colors, making it popular in automotive, appliance, and consumer goods industries.

Powder Coating

Industrial Painting applies liquid or powder coatings to metal, plastic, and composite parts to provide corrosion protection, chemical resistance, or high-grade cosmetic finishes. The workflow combines surface preparation (blast, wash, plasma), controlled paint application (robotic spray, HVLP, electrostatic, dip, or flow-coat), and thermal or UV curing to achieve uniform films that meet OEM colour, gloss, and durability standards.

Industrial Painting

Hard Coating applies wear-resistant layers (e.g., titanium nitride, chromium nitride, DLC) via methods like PVD or CVD, improving durability and corrosion resistance.
