该机是利用电机通过三角带带动振动器，使筛体沿激振力方向作周期性往复振动，物料在筛面做圆运动，从而达到筛分目的。

This machine is used by V-belt motor vibrator so exciting force along the direction of the sieve to make periodic reciprocating, material movement in the screen surface to make a round to achieve the purpose of screening.
优点：
1、 物料筛淌线长，筛分规格多
2、 结构简单，运行可靠，噪音小，电耗低
3、 筛分效率高，处理量大，无冲料现象
4、 可采用封闭式结构机身，防止粉尘污染

Advantages:
1. Long material screening drip line, many screen size
2. The structure is simple, reliable, low noise, low power consumption
3. High efficiency, large capacity, non-washed material phenomena
4. Closed frame structure can be prevent dust pollution
