Weartech SHS: Extend Blower Fan Blade Service Life

Weartech® SHS™ Coating and Overlay Wear Plate
Extend Blower Fan Blade Service Life by 300%


Industrial centrifugal blowers in cement plants provide ventilation of hot gases (≤ 500°C) rich with fine particle dust expelled from high temperature environments inside preheat towers clinker ovens and clinker coolers.

At a cement plant in South America, blower fan blades mounted inside a pair of discs are fabricated from unprotected Q&T steel and not sufficiently resistant to the combination of abrasion, fine particle erosion and corrosion that they are exposed to during service. Material loss from wear and corrosion is severe, requiring replacement after only 2-4 months of service.
