Patent ID: 11369972

Abstract:
The invention relates to a processing system, more particularly a stone crusher, with a filling unit (20), which can be filled with material to be crushed, wherein behind the filling unit (20) in the conveying direction or in the filling unit (20), a screening unit (30) is arranged, wherein the screening unit (30) can be vibrated by means of a vibration generator (38), wherein above the screening unit (30) a part of the supplied material is fed to a connected process unit, more particularly a crushing unit (40), and another part is separated out in the screening unit (30), and wherein the separated-out part of the material is fed by means of an adjustable flap of a conveying unit (70) in a bypass position optionally bypassing the connected process unit, more particularly the crushing unit (40), to a conveying device, more particularly a crusher discharge conveyor (60), or in a conveying position is conveyed out of the machine working area by means of a conveying device (50). To reliably and simply prevent the adjustable flap from becoming blocked by screen material, the invention proposes that the flap is attached to the screening unit (30) in such a way that the vibration generator (38) excites it together with the screening unit (30).
