PROBLEM TO BE SOLVED: To reduce the cost by equipping a screen in which a large number of piano wires are transversely arranged on a screen frame through the prescribed interval on a channel installation type breaking device. ;SOLUTION: A screen S is hinge-connected to a channel installation type breaking device W having two-axis shearing machine 2 at the prescribed angle corresponding to a channel width. In the screen S, a large number of wires 10 are transversely provided on a rectangular screen frame 8 through clearance in the longitudinal direction, and a plurality of eccentric elliptical plate-shaped scrapers 11 which are rotated in the horizontal direction are continuously arranged between the wires 10 through clearances in the transverse direction. The scraper 11 is turned to disturb the flow before the screen S and to prevent the refuse from being entangled around the wires 10, the refuse is moved to the device W, and the function is improved by providing an exciter on the frame 8 as necessary. When only the screen is installed, the refuse at a stagnation point can be prevented from being held. When the screen is continuously installed to the breaking device, the refuse can be broken and discharged downstream, and a pump facility, etc., on the downstream side can be protected.;COPYRIGHT: (C)1999,JPO
