Beschreibung des Kundenbeispiels

Fan Housing fabricated from Duroxite 100 and Mild Steel Plate. Sides cut and fabricated from 1/4 on 1/4 Duroxite Plate. The formed back was fabricated using 3/8” thick Mild Steel with plug welded Duroxite liners.

Wear Life:  The original Fan Housing was fabricated from a AR plate that was lasting approximately 4 months with wear throughout the entire housing, the highest wear in the formed back and bottom.

Design: After studying wear patterns and consulting with the customer over several orders the latest re‐design

includes:

 Removed Mild Steel from the side structure. Sides are now made, not lined, from Duroxite Plate.

 Added side inspection door with flush wear plate on interior.

 Added new formed / bolt‐on replaceable liner.

Benefits:

By fabricating the sides of the housing from Duroxite and not Mild Steel lined with CCO the overall weight of the fabrication has been reduced significantly. The addition of the inspection door with a flush wear plate on the interior has given the customer and inspection port without creating a wear area. The biggest improvement to the design is the formed / bolt on replaceable liner which allows the customer to replace the highest wear zone without replacing the entire fabrication. Continuous improvements to the design has increased the wear life from 4 months to approximately 2 years.
