摘　　要：本文分析了料仓中粉体的应力,推导出了粘性粉体在上为圆筒下为圆锥形料仓中不发生闭塞时的最小卸料口尺寸公式。结合实际情况,分析了粉体水分、粉体压实等因素对闭塞的影响,提出了防止粉体闭塞发生的措施。In this paper, the stress of the powder in hopperes is analysed. The formula of the least calibre size is ascertained for the hopper of a taper under a cylinder when viscous powder do not block. According as practical conditions, the moisture of the powder, the pressure of the powder and other factores effecting on blocking are analysed And the measures to guard against blocking will put forward in this paper.
