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
