Abstract

PURPOSE: To permit a continuous production of a good quality of roundish aggregate by moving obliquely upward the crushed stones in a tubular body arranged in a horizontal position and set in an up-and-down motion into collision with the upper inner wall thereof and moving them downward into collision with the lower inner wall thereof repeating this cyclic round-off operation.
CONSTITUTION: Crushed stones, when introduced into a tubular body 1 set in a up-and-down motion by a crankless mechanism, are accelerated by the upward movement thereof to be raised from a bottom part thereof and then jumped up in the same direction as the tubular body 1 moves in an angular and linear up-and-down motion by a guide member 16 and a slidably movable member 14, i.e., in the upward direction at an angle. Upon the downward movement of the tubular body 1, the crushed stones are vigorously collided with the upper inner wall thereof in order for the angles of the stones to be rounded off and, after this collision, they are dropped into collision with the lower inner wall thereof to cause their angles to be further rounded off and again brought up by the tubular body 1. Thus, such a cyclic movement of the crushed stones against the tubular body is repeated to make the stones increasingly round and hence a suitable aggregate in making concrete.
