This work presents the results of the investigations, devoted to multi-frequency screens, devic-es being used for the screening process and equipped with two drive vibrators operating at various rota-tion speeds. The object of this research was to evaluate the efficiency and capacity of a newly designed double-frequency screen to sieve the grained materials, especially those difficult to separate. The experi-mental double-frequency screen is driven by two inertial drive vibrators operating at various rotation speed, providing complex shaking movement of the screen. In comparison to conventional devices con-taining vibrators operating at constant rotation speed, the application of this modern double-frequency screen resulted in improving parameters of the screening process.
