<p>A stone bevelling machine serves to round corners of bevelling stone. The machine comprises: a cylinder 2 rotating, and having a charge port on one end and a discharge port on the other end; a partition 3 separating the space within the cylinder 2 into a charge port side zone 2a and a discharge port side zone 2b, having a size-regulator gate 32 that selectively allows stones of the specified diameter or smaller to pass through the partition 3; and feeder vanes 24 being fixed at least to inner wall of the charge port side zone 2a and protruding inward. During rotation, stone is cleared of corners thereof to be rounded when small stone, stone powder and stone chips pass through the size-regulator gate 32, so that the processing is enhanced in efficiency. If a trommel 9 is linked to the discharge port of the cylinder 2, it becomes possible to select stone or the like having passed through the discharge port. <IMAGE></p> |
