PROBLEM TO BE SOLVED: To provide a classifier for fine particles of crushed sand capable of reducing the economic liability of the device and improving the operating efficiency by adding a sieving function which mainly aims at the removal of fine particles, etc., contained in crushed sand and at the same time, can remove oversize materials. SOLUTION: In this classifier for fine particles of crushed sand, a sieve net 80, which is a netlike body separated from a classifying surface 3, is attached to the tip part of the lowest receiving plate 32 so as to be arranged in a crushed sand discharge chamber 8, and a crushed sand taking-out port 9 is divided into an undersize material taking-out port 91 formed under the sieve net and an oversize material taking-out port 92 formed ahead of and under the sieve net.
