Polyurethane cleaners are key accessories for belt conveyors, mainly used to clean the adhesive materials and debris on both sides of the belt, ensuring the stable operation of the conveyor belt. They are widely applied in industries such as steel, mining, ports, power plants, coal mines, electric power, and petrochemicals.
Their cutter heads are made of high - performance polyurethane materials, with significant advantages:
- Strong wear resistance: Far higher than ordinary rubber or nylon, it adapts to high - load and high - friction environments, extending service life.
- Good elasticity and high adhesion: Closely adheres to the surface of the conveyor belt, efficiently removing residual materials and reducing belt wear.
- Corrosion resistance and anti - aging: Excellent tolerance to media such as water, oil, acid, and alkali, suitable for harsh working conditions, not easy to age or deform.
- Low friction and low noise: Low friction coefficient during operation, reducing equipment noise and minimizing damage to the belt.
On the conveyor, polyurethane cleaners are often installed at the head (main cleaner) and tail (auxiliary cleaner). Through the spring tension adjuster, when the scraper wears or the belt jumps, the scraper surface will automatically follow up and compensate to ensure close contact with the belt, achieving efficient scraping.
Using polyurethane cleaners can extend the service life of components such as idlers, conveyor belts, and drums, improve the operational efficiency and reliability of belt conveyors, reduce equipment failure rates and maintenance costs, prevent accidents such as conveyor belt deviation, and are essential accessories for belt conveyors.
