摘　　要：为了研究小麦制粉过程中辊间压力对磨辊磨损性能的影响,本文采用与辊式磨粉机工况相似的三体磨料磨损试验机进行磨损试验,考察了在不同载荷压力下小麦粉料对白口铁磨损性能的影响,计算磨损失重,观察磨损表面形貌,分析磨损机制。结果表明:随着载荷的增加,磨损失重增大,磨损量与载荷压力成正比例关系。磨损机理是以显微切削作用为主的磨粒磨损和疲劳磨损交互作用的结果。The three body abrasive wear testing machine which similar to the roller mills was used in wear test, the wear performance of the wheat powder for white iron under different load was investigated, the wear weight loss was calculated, the wear surface morphology was observed and the wear mechanism was analyzed. With the increasing of roller load, the wear mass loss increases, the wearing capacity and roller load have a proportional relationship. The wear mechanism is, the interaction of abrasive wear and fatigue with the micro-cutting plays the leading role.
