Fan Wear-Resistant Solution

11 4 月, 2026

Fan wearing out too fast?
Stop blindly replacing parts!
Use the right methods and extend its lifespan by up to 3×.

In high-dust environments like cement plants,
fan wear is a serious issue.
The main wear areas are the impeller and the volute.

Volute wear hotspots:
Typically located between 1/6 and 1/4 of the volute tongue section.

Impeller wear varies by blade type:

Forward-curved blades: wear at the inlet, outlet, and blade root on the back plate
Backward-curved blades: wear mainly near the outlet, on the side close to the middle plate

Effective wear-resistant solutions require targeted design:

Optimized aerodynamic profile
Wear-resistant structural design
Anti-dust accumulation structure
High-strength materials
Hardfacing (overlay welding) technology

By combining structural optimization with wear-resistant technology,
you can reduce wear at the source and improve durability.

The right wear protection approach
can extend fan life by over 3 times
and significantly reduce maintenance costs.
