Heavy-duty PU conveyor cleaning systems are developed for conveyor applications requiring aggressive material removal and long service life. Installed along the conveyor cleaning zone, the polyurethane scraper blade continuously removes carryback material and prevents buildup on conveyor structures and return rollers. Polyurethane elastomers provide superior resistance to abrasion and impact while maintaining flexible contact with the conveyor belt surface. These cleaner systems help reduce material loss, improve operational efficiency, and lower maintenance costs in bulk material handling industries such as mining, cement, coal handling, and aggregate processing.
