PROBLEM TO BE SOLVED: To provide a classifier which is capable of effectively classifying solid particulates containing large particles (course grain) and small particles (fine particles). SOLUTION: The classifier is prepared by vertically arranging a plurality of folding plates each with a bent part spaced at a distance and being provided with a classification element forming a passage with a cross-sectional folded part by the wall face of the folding plate. Air current containing the solid particulates to be classified is allowed to flow into the folded passage of the classification element. The large particles is trapped by colliding it against the wall face of the folding plate and is trapped by dropping it along with the wall face by gravity. The small particles are classified by accompanying the air current and using a classifier to take out them outside the element. COPYRIGHT: (C)2006,JPO&NCIPI
