The invention relates to electromagnetic vibrators and can be used for sealing concrete mixtures in production of the concrete products, and separation of granular mixtures. An electromagnetic vibrator comprises a base, in the middle of which a rack is mounted, and two electromagnets are located symmetrically relative to the rack, each of which comprises a core with a winding. Armatures of the electromagnets are attached on a plate installed on the rack and elastic elements connect the base with the plate. According to the invention, the plate is elastic and rigidly mounted on the rack. At the ends of the elastic plate reactive masses are symmetrically mounted, through which the plate is connected to the elastic elements mounted on the base. The invention provides reduction of power consumption when using the electromagnetic vibrator. |
