一、概述随着冶金、化工、建材等立业部门广泛地应用筛分机作为各种物料的分级设备,筛分设备的研究日益为人们所重视。现行的筛分设备由于结构上的限制,一般只适用于粗粒和中细粒物料的筛分,对于微细粒物料的筛分,由于筛分效率低,筛网堵塞严重,故不能进行有效的分级。为此,研究微细粒物料高效率的筛分设备一直是一个重要的课题。
First, an overview With the metallurgical, chemical, building materials and other establishments sector widely used screening machines as a variety of materials grading equipment, screening equipment increasingly people’s attention. Due to the structural limitations of the existing screening equipment, it is generally only applicable to the screening of coarse and medium-sized materials. For the screening of fine-grained materials, since the screening efficiency is low and the screen is clogged severely, effective screening can not be carried out Grading. Therefore, it is always an important issue to study the high-efficiency screening equipment of fine-grained materials.
