Flight Edging Benefits
Flight edging is designed to eliminate metal to metal contact between the auger flight and the auger conveyor casing. Flight edging prevents product rollback by decreasing the space between the flight edge and casing.
To estimate the footage required to cover a screw section:
Standard Single/Full Pitch Screw (the pitch is equal to the screw diameter)
Flight Edging Required (ft) = 3.4 x length of screw (ft)
Half Pitch Screw (the pitch is equal to half the screw diameter)
Flight Edging Required (ft) = 6.7 x length of screw (ft)
Special Screw Configurations (undetermined and variable screw pitches)
Flight Edging Required (ft) = .283 x screw diameter (in) x turns
Flight Edging Installation Tips
Spiratex extrudes the UHMW/PE in the helical form slightly smaller than the flight diameter allowing the flight edging to be snapped onto the flight edge. Therefore, the plastic will want to come to rest at the smaller diameter. This uses the forces of the plastic itself to retain on the edge.
Spiratex does recommend "pinning" the edge on one end to keep it from "walking off" the flight edge. We do NOT recommend "pinning" the plastic on every pitch or on both ends as this will fight the thermal expansion/contraction characteristics of UHMW/PE. We also do not recommend any type of glue/adhesive.
