Kenco Drum/Dryer Flights are engineered to provide significantly longer wearlife than all conventional flights. Kenco flights consist of K-Chrome 700 castings bolted to a pre-drilled steel mounting base. With a nominal hardness of 700 Brinell, Kenco castings will not fold over or distort from wear. Product literature (PDF).
Proper veiling profile for optimum aggregate drying is maintained longer with Kenco Drum/Dryer Filghts, keeping burner fuel consumption consistently at "day-one" levels.
Conventional asphalt drum/dryer flights commonly wear thin on the backside, due to the veiling action of falling material. As soon as they fold over (or break), proper veiling profile is lost and aggregate drying efficiency becomes severely compromised. Plant productivity suffers from sharp increases in burner fuel consumption and/or reduced tons per hour output.
Calculate your wasted fuel cost. It may be more than you think!
Kenco does not design or recommend flight styles/specifications, and is not responsible for material veiling profile inside the drum or dryer. Our flights match the dimensions of the worn original flights, but because of superior wear material they will last many times longer.
Worn flights inside a drum or dryer cause the veiling profile to deteriorate. When the veil is sub-optimal, aggregate material may not be properly dried, resulting in compromised mix quality. Improper aggregate drying will require the plant operator to slow down plant output and/or increase fuel consumption, both costly options. Kenco flights help avoid these problems because they significantly outlast all conventional flights.
