High-performance vibration screen

A vibration screen comprises a case-shaped body with parallel side walls between which perforated screening surfaces are disposed and which is suspended by spring means over a base and is provided with vibrating devices. The side walls are each at least partly made up of two plate sheets closely spaced and parallel, so that each of them forms one of the two faces of the wall and delimits a hollow space therebetween. The sheets are interconnected with each other by means of interconnecting elements disposed in the hollow space
