悬辊式磨粉机（以下简称悬辊磨）在矿物、陶瓷、玻璃、石膏、石灰石、燃煤及农药等物料的粉碎中有广泛的应用。近些年来，在传统机型的基础上，有些专家学者提出了新型悬辊磨的磨矿机理、设计理论、以及用分级机改良传统机型生产微细粉等等。［１］［２］但对铲刀，至今仍缺乏 Suspended roller mill (hereinafter referred to as the suspension roller mill) in the minerals, ceramics, glass, gypsum, limestone, coal and pesticides and other materials crushing has a wide range of applications. In recent years, on the basis of traditional models, some experts and scholars have proposed the grinding mechanism and design theory of the new type of suspension roller mill, as well as the improvement of the traditional models by the classifier to produce the fine powder and so on.
