Abstract
In the coal mine transportation, the scraper conveyor chute is badly worn. However, the abrasion performance has not been well documented. In this study, the chute was wear tested under a single factor using a modified pin-on-disc apparatus, including normal load, sliding distance, bulk coal characteristics (water content, gangue content), and chute material. Experiments were also carried out with a simultaneous variation of these factors. Generally speaking, the influence of coal characteristics on the chute wear was obviously higher than that of normal load and sliding distance. An improved wear predict model was obtained taking the operational parameters and bulk coal characteristics into account. The wear mechanism involved micro-ploughing, corrosion, adhesion, and fatigue peeling.
