Buffer rollers are specifically designed for belt conveyors at material receiving points to reduce the impact of material falling onto the conveyor belt. They are primarily developed for corrosive environments such as coal washing plants, coking plants, and chemical plants. These rollers possess toughness that exceeds ordinary metals by more than ten times. They are corrosion-resistant, anti-static, and do not damage the conveyor belt, making them widely used in mining operations. The superior anti-corrosion performance of buffer rollers allows them to have a lifespan that can exceed that of regular rollers by more than five times when used in corrosive environments.
