• The handling capacity of a vertical bucket grain elevator of centrifugal discharge type, which was deficient owing to the low discharge efficiency, was considerably improved by changing the shape of the bucket. Further researches on the behavior of grain during discharge were carried out on a model equipment and the following results were obtained. In regard to the discharge efficiency the bottom and top angles of the bucket are essential factors and those exceeding 25°and 70°respectively seem to be more favorable. If the bottom angle is smaller than 25°, some part of the grain falls without reaching the chute ; if the top angle is smaller than 70°, some quantity overflows before the bucket arrives at the top position. Most of the grain discharged passes closely over the bucket edge in an approximately parabolic motion with an initial velocity nearly equal to the circumferential velocity of the edge.
