Study on Wear of Scraper Conveyor Chute - Atlantis Press

Abstract. The wear of the middle trough of coal mine scraper conveyor, is a common fault of scraper conveyor. Starting with the causes of wear by analyzing the structure and the working condition of the chute, it indicates that the friction is the main cause of the chute wear, and abrasive wear, adhesive wear, fatigue wear and corrosion wear are the main forms of chute failure. The use of new materials and strengthening the maintenance can prevent the chute wear of scraper conveyor
