Conveyor Screws

Helicoid

Newton Conveyors’ Helicoid conveyor screws are cold rolled from special analysis strips on unique rolling mills designed specially for this purpose.

 Although the rolling operation compresses the outer flight edge, or periphery, to approximately 50% of the inside root, the cold-rolling process produces a smooth, work hardened surface which actually increases wear resistance.

Dimensional tolerances of all Newton conveyor screws conform to industry standards established by the Conveyor Equipment Manufactures Association.

 To produce the complete conveyor section, the continuous, one piece helix is mounted on the conveyor pipe with heavy duty end lugs and regularly spaced intermediate welds. For special applications, the flighting may be continuously welded to the pipe on one or both sides.

 Pipe ends are bushed with close-tolerance internal collars which are pressure inserted and plug-welded for maximum efficiency and service life. The collars are accurately reamed for the proper coupling shaft diameter. Coupling bolt holes are jig-drilled for perfect alignment.

 Helicoid conveyors may be furnished in various materials, and some specific sizes are available in stainless steel (see Helicoid Flighting Dimensional Table). Helicoid screws may also be furnished with hard-surfaced flights.

 Standard helicoid conveyors are interchangeable with standard sectional flight conveyors (see Comparison Table).

 Numerous deviations from standard are available for virtually any application. For description of basic flight types, including most common flight modifications and pitch deviations (see Basic Conveyor Flight and Pitch Types).

Sectional

Newton Conveyors’ Sectional flight conveyor screws consist of individual flight segments which are cold formed form separate flat-plate blanks and then butt-welded to form the helix.

 Then the flights are anchored securely at each end of the conveyor pipe by formed steel lugs and with carefully spaced intermediate welds. For severe conveying applications, the flights may be continuously welded to the conveyor pipe on one or both sides.

 Sectional flights, unlike helicoid flighting, have uniform thickness at the outer edge and inside root. Sectional conveyors are available in a wider range of sizes, materials, weights and thickness. (See Sectional Flight Dimensions Table)

 All Newton sectional conveyor screws are available in stainless steel. They may also be furnished in abrasion resistant steel or may be hard surfaced for longer service life.  Virtually any combination of flight thickness, diameter, pitch and materials can be furnished to suit almost any conveying application.

 As with the helicoid , pipe ends are bushed with standard Newton internal collars. The collars are pressure fitted, plug-welded and reamed for the appropriate coupling diameter. Coupling bolt holes are jig-drilled for perfect alignment.

 Sectional flight conveyor screws are fully interchangeable with standard helicoid conveyors (see Comparison Table).

 Numerous deviations from standard are available for virtually any applications. For description of basic flight types, including most common flight modifications and pitch deviations (see Basic Conveyor Flight and Pitch Types).
