PROBLEM TO BE SOLVED: To provide an apparatus for cooling, sieving and transporting pellets which can transport the pellets produced by a pelletizing apparatus to a transportation destination place by using a simple device without crushing the pellets while cooling and sieving the pellets.SOLUTION: An apparatus 2 has a classifying transporting member which transports pellets from a transportation starting place 1 to a transportation destination place 3 while classifying the pellets and a cover member 22 which covers the classifying transporting member. The classifying transporting member has a cylinder sieve 21 which leaks no pellet but leaks broken pieces that are smaller than the pellet and a screw wall which is fixed to the inside of the cylinder sieve 21 and spirally partitions its internal space. Further an outer peripheral edge of the screw wall comes into contact with an inner surface of the cylinder sieve 21, the cylinder sieve 21 and the screw wall integrally rotate around an axis. Moreover the cover member 22 is provided with an exhaust port 30 for discharging the broken pieces leaked from the cylinder sieve 21 below the cylinder sieve 21 and an air hole for making air flow inside from outside at a place different from the exhaust port 30. |
