The scraper conveyor is the key conveying equipment for fully mechanized coal mining. Wear failure of the chute is the main form of failure of the scraper conveyor. In this study, the discrete element method (DEM) was combined with the wear model. The wear mechanism and wear regularity of the chute were explored by tracking the changes in the position of coal particles during the wear process.
Coal Crushing. The record speaks for itself: since 1908, hundreds of millions of tons of coal have been reduced using American Pulverizer machines. We are the standard of comparison for central stations, industrial power plants, and mine preparation plants around the world. We make many types of coal crushing equipment, like our ACC Series ...
The wear of scraper conveyor chute causes both significant economic and environmental losses by shortening the service life. The life of the chute under coal abrasive wear situations is primarily decided by operating conditions and the materials properties. The comprehensive analysis of the influence factors had not been studied before. In this paper, the PlackettBurman design (PBD) method ...
