Cement Plant Fan Impeller Wear-Resistant Ceramic Wear Solutions

Cement Plant Fan Challenges and Wear Mechanism

Cement plant fans play a critical role in maintaining airflow and managing dust particles within the industrial setting. However, these components endure continuous abrasion and impact due to the high-speed airflow carrying solid particles and dust. This constant wear and tear often lead to frequent replacements and maintenance, resulting in reduced efficiency and unnecessary resource wastage within the plant.

Impeller Wear Mechanism Analysis

Particle Hardness Impact:

The wear and tear experienced by impellers directly correlate with the hardness of the particles they encounter. Ingressing particles exhibit varying levels of hardness, contrasting with the impeller's hardness affected by its material composition and wear-resistant coatings.

• 1. Micro-Cutting: Low-angle abrasive dust flows impose tangential forces on impeller surfaces, leading to material loss through particle edge cutting. This initial cutting manifests as surface scratches that evolve into abrasions after multiple impacts.

• 2. Surface Enhancement: Enhancing impeller surface hardness effectively combats micro-cutting. Smoother surfaces reduce friction and subsequently weaken the abrasive impact on the impeller.

High Impeller Hardness vs. Poor Fracture Toughness:

In scenarios where dust-laden airflow hits the impeller at high angles, it induces surface tensile forces. These forces result in radial and lateral cracks, forming interconnected circular fractures that lead to chunk detachment—a primary mechanism for high-angle erosion material loss.

• Resolution: Optimizing the impeller's material composition or utilizing wear-resistant coatings significantly enhances fracture toughness, mitigating the effects of high-angle erosion.
