直线振动筛概述
  直线振动筛利用振动电机激振作为振动源,使物料在筛网上被抛起,同时向前作直线运动,物料从给料机均匀地进入筛分机的进料口,通过多层筛网产生数种规格的筛上物、筛下物、分别从各自的出口排出。具有耗能低、产量高、结构简单、易维修、全封闭结构,无粉尘溢散,自动排料,更适合于流水线作业
直线振动筛工作原理:
  直线振动筛采用双振动电机驱动,当两台振动电机做同步、反缶旋转时,其偏心块所产生的激振力在平行于电机轴线的方向相互抵消,在垂直于电机轴的方向叠为一合力,因此筛机的运动轨迹为一直线。其两电机轴相对筛面有一倾角,在激振力和物料自重力的合力作用下,物料在筛面上被抛起跳跃式向前作直线运动,从而达到对物料进行筛选和分级的目的。 可用于流水线中实现自动化作业。具有能耗低、效率高、结构简单、易维修、全封闭结构无粉尘溢散的特点。最高筛分目数325目,可筛分出7种不同粒度的物料。
