Drum is a highly versatile cylindrical transmission/support component in industrial equipment, with core uses centered around power transmission, material conveying, directional guidance, and support buffering. Different types of drums have their own specific applications in conveyor, mining, logistics, printing, and other fields, classified as follows:

Drive drum (Active drum)

Core use: As the power output core of the conveyor, it is driven by a motor to rotate and use friction to drive the conveyor belt or transmission belt to operate, directly determining the operating speed and load-bearing capacity of the conveyor system.

Applicable scenarios: mining belt conveyors, port bulk material conveyors, and large-scale production line conveying equipment.

Reversing drum (driven drum)

Core application: Change the running direction of the conveyor belt, extend the wrap angle between the conveyor belt and the driving drum, increase the transmission friction, and prevent the conveyor belt from slipping; Partial redirection rollers can also be used in conjunction with tensioning devices to adjust the tension of the conveyor belt.

Applicable scenarios: The head, tail, and winding sections of a conveyor, such as the turning point of a belt conveyor in a sand and gravel production line.

Roller type drum

Bearing roller: supports the weight of the conveyor belt and the materials above it, reduces the running resistance of the conveyor belt, and ensures smooth transportation. It is the most commonly used type of roller in belt conveyors.

Return idler: supports the empty section (return section) of the conveyor belt to prevent sagging and deviation, and extends the service life of the conveyor belt.

Buffer roller: installed at the feeding point of the conveyor to buffer the impact force of falling materials and prevent the conveyor belt from being damaged by materials. It is commonly used in heavy-duty conveyors in the mining and coal industries.

Self aligning idler: Real time correction of conveyor belt deviation issues, ensuring that the conveyor belt always runs in the center position and reducing equipment failure rates.

Tensioning drum

Core use: Adjust the tension of the conveyor belt to maintain sufficient friction between the conveyor belt and the drive drum, preventing slipping; Simultaneously compensate for the length changes of the conveyor belt caused by stretching.

Applicable scenarios: Tensioning devices for various types of belt conveyors.

Other special purpose rollers

Rubber coated drum: The surface of the drum is covered with a rubber layer to enhance friction and wear resistance, and is commonly used in high load and slip prone conveying scenarios.

Electric drum: Integrating the motor, reducer, and drum into one, simplifying the structure of the conveyor, it is commonly used in small assembly lines and logistics sorting lines.
