Screening system, eddy current screening machine, and use of screening system or eddy current screening machine

摘要

The invention particularly relates to a screening system (10), which system comprises at least one first substantially annular screen support (11) and a second substantially annular screen support (12), and a screen. A clamp between the screen support (11, 12) and at least one pressure rod (14) that holds the screen support (11, 12) together so that compressive stress is generated between the support (11, 12). At least one substantially cylindrical outer screen surface (13) and at least one resonator (15) for introducing ultrasonic vibrations directly into the screen surface (13). According to the first embodiment of the invention, the resonator (15) is fixed to the screen surface (13) and extends substantially from the first screen support (11) to the second screen support (12). To do. The invention further relates to an eddy current screening machine and the use of a screening system (10) or an eddy current screening machine.
