ABSTRACT
This paper deals with effects of damaged steel-case rollers on a 3D bridge frame subjected to loadings due to the moving belt resting on conveyor idler sets roll, the underlying conveyor belt support frame, and the transported materials contained corrosive material to be moved during full-capacity transport. To design a conveyor belt, data on conveyor bridges is required, as well as calculations for resistances. The driving force on driving pulleys consists of many force components; however, some of them are required to make experimental measurements, such as for rotational resistances. Comparative tests were used on two same pieces of roller. The research objects were idlers, used in conveyor belt systems for bulk transportation. Measurement campaigns were conducted in phosphoric acid baths to save time. Neglecting maintenance can lead to breakdowns, causing unplanned downtime and productivity loss. Regular checks and repairs keep the system running smoothly and prevent costly interruptions.
