China Suppliers Factory for High-Quality Reversing Drum Bend Pulley for Belt Conveyor Systems
Function and Application
1. This component has two main functions:
①
By changing the direction angle by 180°, the trajectory of the conveyor belt can be altered, with 180° turning being commonly used at the rear of the conveyor.
②
Tighten the conveyor belt to increase its contact angle with the drive pulley, and the increase in angle can reach 30% – 50%, effectively preventing slipping.
2. Application Scenarios:
- Mining: Belt conveyor system for the main transportation roadway underground in coal mines.
- Port Loading & Unloading: The turning node of continuous loading and unloading equipment at bulk cargo terminals.
- Metallurgical Production: Turning device for high-temperature material conveying line in steelmaking plant.

Frequently Asked Questions
QWhat is a bend pulley and what is its primary function?
A bend pulley is a conveyor system component used to change the direction of a conveyor belt by up to 180°. It is also used to increase the contact angle between the belt and the drive pulley, helping to prevent belt slippage during operation.
QWhat sizes and shaft diameters are available for the bend pulley?
The bend pulley is available in five diameter sizes: 220, 320, 400, 500, and 600 mm. Shaft diameters come in three options: 40, 50, and 60 mm. The cylinder body length ranges from 500 to 1400 mm, with custom sizes available upon request.
QWhat industries commonly use bend pulleys?
Bend pulleys are widely used in the mining industry (especially coal mine underground conveyor systems), port bulk cargo terminals for continuous loading and unloading, and metallurgical plants for high-temperature material conveying lines.
QWhat is the dust-proof rating of the bearing housing?
The sealing structure of the bearing housing meets the IP54 dust-proof standard, making it suitable for use in harsh environments such as mining tunnels and industrial production facilities where dust and debris are common.
QHow much can a bend pulley increase the belt contact angle?
By using a bend pulley to tension the conveyor belt, the contact angle with the drive pulley can be increased by 30% to 50%, which significantly reduces the risk of belt slipping and improves overall conveyor system efficiency.
QCan bend pulleys be customized to meet specific project requirements?
Yes. In addition to the standard specifications, bend pulleys can be fully customized in terms of diameter, shaft size, and cylinder body length to meet specific engineering and project requirements. Please contact us with your technical parameters for a tailored solution.
