Introduction to the idler rollers for belt conveyor modification

The swivel drum, also known as the guiding drum, is a common component in belt transportation machinery. It is mainly used to change the running direction of the conveyor belt or to press the conveyor belt tightly to increase the angle between it and the drive drum.

The swivel drum is mainly located beneath the conveyor belt. If the conveyor belt is moving to the left, then the swivel drum is on the right side of the belt machine. Its main structure consists of bearings and a steel cylinder. The swivel drum is the driving wheel of the belt machine. In terms of their relationship, it's similar to the two wheels of a bicycle. The rear wheel is the swivel drum and the front wheel is the driving wheel. There is no difference in structure between the swivel drum and the driving drum. Both are composed of a main shaft, a drum bearing, and a bearing chamber. The swivel drum is divided into main drive and secondary drive.

The swivel drum is applicable to machinery, metallurgy, mining, ports and docks, chemical and pharmaceutical industries, cement and building materials, steel, and coal mines. It serves as the driving device for various mobile conveyors and can also be used for certain fixed belt conveyors. The swivel drum features a compact structure, light weight, low space occupation, reliable performance, good appearance, easy operation, and the ability to work normally even in harsh conditions such as high dust, dampness, and mud.
