The dust-containing air inside the box body 1 is blown out of the box body 1 by the dust removal fan 27, thereby reducing a large amount of dust from accumulating on the internal components of the box body 1 and affecting the operation of the internal components. By setting the anti-slip pad 26 and the box door 29, the box door 29 is closed when not in use to reduce dust from entering the box body 1.The anti-skid pad 26 increases the friction with the ground, reduces the movement of the classifier during use, and improves the stability of the classifier during use.
