Study on dynamic characteristics of scraper conveyor under various scraper configurations

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering
This study aims to explore the impact of scraper structure on the stable operation of scraper conveyors. A simulation test is designed to investigate the effect of the scraper's lower inclination angle on the wedge-shaped structure of the scraper. Based on the test results, modifications are made to the scraper's lower inclination angle.
