Secondary polyurethane conveyor cleaners are installed after the primary scraper to remove fine particles and stubborn residual material from the conveyor belt surface. The polyurethane blade conforms closely to the belt and maintains efficient cleaning performance under continuous operation. High-quality PU material offers exceptional abrasion resistance and impact durability while maintaining stable flexibility. These systems reduce carryback accumulation on return rollers and conveyor frames, improving conveyor reliability and reducing maintenance requirements. Polyurethane secondary cleaners are widely used in mining, cement plants, recycling systems, and aggregate production facilities.
