PROBLEM TO BE SOLVED: To provide a granule sieving machine capable of surely performing proper treatment granules with the sieving machine when the granules are supplied to the sieving machine in an amount exceeding the treatment capacity of the machine. SOLUTION: This sieving machine has a baffle 15 placed in the vicinity of an opening 1d which is provided with: a clearance 150 that is formed between the baffle 15 and the opening 1d and has a size sufficient to remove foreign matter such as bolt or nut; a baffle plate 151 having a disk 151a and a circular return plate 151b formed on the periphery of the disk 15a; plural (e.g. twelve, as shown in the figure) fins 152 each of which is formed in the radial direction of the circular baffle plate surface facing the inside region 4a of the baffle plate 151 and inclined in the counterclockwise direction when viewed from the side of a motor 11; and a boss 156 which has a through-hole 153, a key groove 154 and a tapped hole 155 and is formed in the central part of the circular return plate 151b. Thus, such trouble that when as the sieve 8, a sieve having very fine mesh size is used, a portion of the undersize granules to be allowed to pass through the sieve 8, fails to pass through the sieve 8 and to enter into an outside region 4d of the sieve chamber and accordingly, an excessive amount of such an undersize granule portion is discharged through the over-outlet 10 by driving force applied to the granule portion, is prevented from being caused.
