摘要
由于原煤含有大量高硬相的矸石、铁矿石、掺杂的铁物、以及含磁铁矿粉的重介质溶液等,因此,对选煤设备中很多零部件的耐磨性要求较高。如何检测它的耐磨性,目前国家还没有专门的标准。因此找到一种简单的、适合生产应用、能准确评测材料耐磨性的评测方法是十分迫切的。
Since raw coal contains a large number of hard gangue,iron ore,doped iron,and medium solution with magnetite,it requires high wear resistance to many parts of coal-electing equipment.Our country has no special standard to detect the wear resistance.Therefore,it is insistent to find a simple and accurate detection method.
