VIBRATORY SEPARATOR Russian patent published in 2015 - IPC B07B1/40 

FIELD: process engineering.

SUBSTANCE: invention relates to separators and can be used for separation of solid particles to preset sizes, first of all, hard-to-sieve powders with bent to nodulising and plugging of screen meshes, etc. Separator comprises sieve fitted in the case. Activator coupled with multi-frequency adapter system is arranged under sieve along with vibration drive. Note here that said case is rigidly coupled with the bed. Vibration drive is composed of two or more pairs of electromagnets arranged on opposite sides of said case in opposition to allow their synchronous operation. Electromagnet coils are secured at the case. Armatures are connected with activator composed of two or more parts. Every part of the activator is connected with armatures of their pair of electromagnet. Adjacent pairs of electromagnets allow operation with phase shift. Every said pair is provided with independent frequency and/or voltage adjustment.

EFFECT: simplified design, expanded applications.
