Material conveyed by conveyor belts often contains sticky substances like coal dust, slurry, and powdered materials. Some of these substances adhere to the working surface of the belt, and during unloading, they cannot be completely removed. As the belt rotates, they stick to the idlers, leading to the following consequences over time: 1. Material enters the housing of the idlers, increasing bearing wear. The accumulation of material on the idler housing can damage and abrade the conveyor belt's surface rubber, accelerating belt wear. 2. Adhesives enter the tail pulley and reversing roller, causing material to stick to the roller surface, accumulating more with time. This leads to belt misalignment, increased belt wear, and adverse effects. 3. Material sticking to the drive roller increases friction, potentially damaging the conveyor belt's surface rubber and the roller's rubber lining. 4. Failure to remove material promptly creates a falling material area along the entire working channel, causing environmental pollution, increased cleaning labor, impacting employee health, and raising corporate costs. Therefore, to ensure the normal operation of the belt conveyor, it is essential to clean the adhered materials from the belt. A well-functioning cleaning device can extend the life of idlers, conveyors, and other components.
