Preferably, the dust collection box is in an inverted quadrangular frustum pyramid shape, and the lower end of the dust collection box is communicated with a dust collection device. The dust collection box is further preferably a quadrangular frustum pyramid type dust collection box, and the included angle between the height of the dust collection box and the side face is 15-30 degrees.

By increasing the height of the dust collection box, the outline of the dust collection box is stretched, the angle of the dust collection box becomes steep, and powder can slide down conveniently instead of being accumulated on the inner wall of the dust collection box.

Preferably, the screening surface has a rectangular profile and the ratio of the length to the width of the screening surface is greater than 1 and less than 2.

By increasing the width of the screening surface, the thickness of the material on the screening surface is reduced, i.e. the material on the screening surface is thinner, which contributes to a more adequate screening.

The utility model has the advantages that:

1) through setting up control flashboard, make the material on the screening surface in single layer or double-deck or 3 layers, help the screening thoroughly.

2) Set up the brush tooth on the control flashboard, except having detached the powder on the material through the vibration effect, when the material moved to the discharge gate on the sifter, through the brush tooth, can further detach the powder on the material.

3) By increasing the height of the dust collection box, the outline of the dust collection box is stretched, the angle of the dust collection box becomes steep, and powder can slide down conveniently instead of being accumulated on the inner wall of the dust collection box.

4) By increasing the width of the screening surface, the thickness of the material on the screening surface is reduced, i.e. the material on the screening surface is thinner, which contributes to a more adequate screening.

5) Through the thickness of flashboard control material, through the width that increases the sifter, further reduce the thickness of material, help abundant screening, through the height that increases the dust collection box for the powder that is sieved down slides down fast, thereby reduces the powder of dust collection box and because of receiving the condition that the vibration rises and returns the sifter.
