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. |
