FIELD: separating solids from solids.

SUBSTANCE: machine has frame and screen whose side edges are provided with convex caps. The screen is rigidly connected with the first end of the shaft inclined to horizontal plane and connected with the frame through bearing units. The shaft is set in rotation with an asynchronous three-phase motor whose one winding is connected with the AC power source. The other two windings are connected in series and connected with the output of a one-phase frequency converter whose input is connected with the AC power source. The pad for grain fractions is mounted on the shaft through bearing units.
