旋振筛在筛分玉米面时是怎么运行的呢?

    玉米作为部分粮食深加工企业的生产原料,在采集、运输和贮存过程中不可避免将掺入杂质。杂质的存在,一方面造成玉米加工设备的堵塞,使磨损加剧;另一方面杂质带入产品中,造成产品质量下降甚至不合格。鼠笼式旋转筛是大型理玉米杂质的主要设备,为提高旋转筛使用效果,针对玉米的清理要求,需要调整旋转筛的倾角、筛孔尺寸、转速等参数,以达到预期的使用目的。旋转筛面一般呈圆筒或多角形筒,其运动是绕筛筒自身水平轴或倾斜轴旋转,玉米在筛筒内进行筛理,筛上物为大杂排出,筛下物为玉米。筛理能力和效率与旋转筛的转速、开孔、结构有关。收稿日期:2012-07-29要:鼠笼式旋转筛是大型工厂清理玉米杂质的主要设备,通过分析玉米在旋转筛面内的运动机理,确定旋转筛最合理的工作参数,为设备的选用和调整提供参考。

以六角筛为例做玉米运动分析,设六角筛筒的最小半径为r(m),以匀角速度 ω(r/s)逆时针绕水
平轴旋转,筛筒中玉米受力
