Ceramic-Coated Screw Flight - Advanced Wear-Resistant Conveying Solution

Product Overview

The Ceramic-Coated Screw Flight is a high-performance wear-resistant component designed for heavy-duty material handling applications. Developed by Jiahe Conveying Equipment Technology Co., Ltd, this innovative product combines the structural strength of high-grade steel with the exceptional abrasion resistance of advanced ceramic coatings, significantly extending the service life of screw conveyors in harsh operating environments.

Key Features

1. Superior Wear Resistance

• Alumina Ceramic Coating: The screw flight surface is protected by a dense layer of 92%-96% alumina ceramic, offering hardness up to HRA88-90 (equivalent to HRC70+), which is 5-10 times more wear-resistant than hardened steel.

• Impact-Resistant Design: Special ceramic tile arrangement and shock-absorbing adhesive layer prevent ceramic detachment under high-impact conditions.

2. Extended Service Life

• 10-15x Longer Lifespan: Compared to standard carbon steel flights, our ceramic-coated versions last significantly longer when conveying abrasive materials like cement, fly ash, or mineral ores.

• Maintenance Reduction: Minimizes downtime for flight replacement, reducing operational costs by up to 60% over 5 years.

3. Optimized Material Flow

• Low-Friction Surface: Ceramic's smooth surface (Ra ≤ 0.2μm) reduces material buildup and improves conveying efficiency by 15-20%.

• Anti-Corrosion Properties: Ideal for wet or chemically aggressive environments where standard flights would corrode.

4. Custom Engineering Solutions

• Variable Coating Thickness: 3-15mm ceramic layer options for different abrasion levels.

• Modular Design: Replaceable ceramic segments simplify repairs without dismantling the entire screw.
