VIBRATING SEPARATOR OF LOOSE MATERIALS Russian patent published in 2024 - IPC B07B1/40 B07B1/42 

FIELD: machine building.

SUBSTANCE: proposed invention relates to devices for separation of loose materials, including for separation of grain mixture. Vibrating separator of loose materials comprises a bearing box, a hopper for loading loose material and feeding it to a sieve mill, trays for collection of separated fractions of material and two vibration exciters shifted to opposite ends of sieve mill. Vibration exciters are made in the form of three-phase two-pole synchronous electric motors, which rotors are made of magnetically hard material, installed in stator with unbalance due to loads. Three-phase stator windings are connected to the power supply source for the same direction of rotation for both electric motors.

EFFECT: higher reliability and performance criterions of separator.
