The lower screen 11 is arranged at the bottom of the upper screen 10, and the screening frame is arranged at the bottom of the lower screen 11.

The aperture of the screening chamber increases gradually, and effective hierarchical screening is achieved to improve screening accuracy.

[0029] The screening frame structure is overall in the shape of a long strip, and the screening structure remains inclined at an angle of 30-35 degrees, which can promote the automatic sliding of the raw materials.
