Abstract
The invention relates to, inter alia, a screening system (10), comprising: at least one first substantially annular screen support (11) and a second substantially annular screen support (12); at least one pressure rod (14), which braces the screen supports (11, 12) with each other in such a manner that a compressive stress is produced between the screen supports (11, 12); at least one substantially cylindrical outer screen surface (13), which is clamped between the screen supports (11, 12); and at least one resonator (15) for the introduction of ultrasonic vibrations directly into the screen surface (13). According to a first embodiment of the invention, the resonator (15) is fastened to the screen surface (13) and essentially runs from the first screen support (11) to the second screen support (12). The invention further relates to an eddy-current screening machine and to the use of a screening system (10) or of an eddy-current screening machine.
