    Dual Hardness Cleaner – Product Description

    Product Overview
    The Dual Hardness Cleaner is a high-performance conveyor belt cleaning system designed with a two-layer blade structure: a softer polyurethane base for belt protection and a harder wear-resistant scraping edge for efficient material removal. This dual-compound design provides exceptional cleaning efficiency while maximizing belt life, making it ideal for heavy-duty mining, aggregates, cement, coal handling, and bulk material processing applications.

    The cleaner delivers consistent cleaning pressure, reduced carryback, and long service life—significantly improving overall conveyor efficiency and reducing maintenance downtime.

    Key Features

    1. Dual-Compound Blade Design

    The blade combines soft polyurethane for flexibility and belt contact + harder wear-resistant PU or carbide for strong scraping force. This ensures powerful cleaning while preventing belt damage.

    2. High Cleaning Efficiency

    The harder top edge removes stubborn material, slurry, mud, and fines, reducing carryback and keeping the belt surface clean for smooth operation.

    3. Long Service Life

    Hardness-optimized materials increase resistance to abrasion, chemicals, and impact. The dual hardness structure extends cleaner lifespan by 2–3 times compared with standard cleaners.

    4. Belt-Friendly Structure

    The softer polyurethane base absorbs vibration and provides uniform tension, protecting the belt surface and prolonging belt life.

    5. Easy Installation and Maintenance

    The modular blade design allows quick replacement without removing the entire cleaner assembly. Compatible with multiple tensioning systems.

    6. Stable Operation Under Heavy Load

    Performs reliably in both wet and dry conditions, even under high-speed, high-load, and highly abrasive environments.
