A return strand cleaner is an essential component in conveyor belt systems, specifically designed to maintain the efficiency and longevity of the belt by minimizing material accumulation on the return side. Installed on the bottom face of the belt, this cleaner operates by utilizing a blade that comes into contact with the belt surface to scrape off adhering materials. The effective removal of these materials prevents uneven wear on return idlers and reduces the potential for spillage, which can lead to environmental hazards and increased maintenance costs. The design often includes adjustable spring mechanisms that allow for optimized contact pressure, ensuring that the cleaner adapts to varying conditions and material types.
The return strand cleaner is particularly beneficial in applications where highly adhesive materials, such as wet clay, wet coal fines, or sticky mineral ores, are transported. These materials can easily cling to the belt, leading to significant operational challenges if not properly managed. By complementing the V-type cleaner, which is effective in handling bulk materials, the return strand cleaner ensures a comprehensive cleaning strategy that addresses both the carrying and return sides of the conveyor system.
Blade materials for these cleaners typically include rubber, polyurethane, or nylon, each chosen for their durability and effectiveness in specific environments. The selection of blade material is crucial, as it influences the cleaner's performance and lifespan. For instance, polyurethane blades are often preferred for their resistance to wear and tearing, making them suitable for more abrasive materials. Overall, the implementation of a return strand cleaner is a proactive measure in conveyor belt maintenance, contributing to improved system reliability and reduced downtime.
