[0002] Conveyor rollers are widely used and crucial in mining operations. These rollers not only bear the weight of the material but also play a decisive role in the efficiency and safety of the entire conveying system. Technically, conveyor rollers are classified in various ways, including load-bearing rollers and return rollers, depending on their function. The choice of material is also crucial.
