A rubber screen having expandable sorting holes is provided to make a design simple and to reduce the unnecessary waste of materials by widening the sorting holes by vibration and boring the sorting hole corresponding to the size of an object. A rubber screen(100) is composed of: a body(110) produced in a square plate form in one of vertical and horizontal directions by using a conveyor belt including at least one fold of cover fabrics or cord yarns, polyurethane, or wear-resistant rubber; plural sorting holes(120) formed in a circle, square, lozenge, or polygon and continued at regular intervals in a line in a longitudinal direction of the body, wherein the adjacent lines of the sorting holes cross each other; a cut part(130) for expanding the size of the sorting hole by cutting the sorting holes adjacent to each other in a longitudinal direction of the body; and combining tools(140) for installing the body to both frames. |
