PROBLEM TO BE SOLVED: To make certainly sortable bad spheres such as W-balls or the like mixed in extremely small spheres manufactured by an atomizing method. SOLUTION: A V-groove 1 is provided to a chuter 1 arranged so as to be inclined downward in a forward direction and spheres to be sorted are charged in the groove to apply directionality to the movement of the spheres. By this constitution, good spheres roll down at a high speed and bad spheres don't roll down to slip down at a slow speed and a difference is generated between the carrier of both spheres discharged from the chuter. Good and bad spheres are sorted by a sorting plate 2 on the basis of the carry difference.
