Bend Pulley for Belt Conveyor System - China Suppliers & Factory for Metallurgy, Mining, and More
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
What is the primary function of a bend pulley in a conveyor system?
A bend pulley serves two main functions: it changes the direction of the conveyor belt by up to 180°, and it tightens the belt to increase its contact angle with the drive pulley by 30%–50%, effectively preventing belt slippage.
What diameter sizes are available for the bend pulley?
The bend pulley is available in five standard diameter sizes: 220 mm, 320 mm, 400 mm, 500 mm, and 600 mm. Custom sizes can also be manufactured based on specific customer requirements.
What shaft diameter options does the bend pulley support?
The bend pulley supports three levels of shaft diameters: 40 mm, 50 mm, and 60 mm, covering a wide range of conveyor system requirements.
What industries commonly use bend pulleys?
Bend pulleys are widely used in mining (underground coal mine belt conveyors), port loading and unloading operations (bulk cargo terminals), and metallurgical production (high-temperature material conveying lines in steelmaking plants).
What is the dust-proof rating of the bearing housing on this bend pulley?
The sealing structure of the bearing housing meets the IP54 dust-proof standard, making it suitable for harsh industrial environments such as mining and metallurgy where dust and debris are prevalent.
Can the bend pulley cylinder body length be customized?
Yes. The standard cylinder body length ranges from 500 mm to 1400 mm. Beyond this range, customized lengths are available to meet specific project or equipment requirements upon request.
