Description du cas

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.
