CENTRIFUGAL SEPARATOR FOR SEPARATION OF BULK MATERIAL Russian patent published in 2008 - IPC B04B3/00 B07B1/22 

FIELD: food-processing industry, in particular, equipment for separation of bulk material into fractions of different sizes.

SUBSTANCE: centrifugal separator has casing with branch pipes for feeding of bulk material to be separated and discharge of bulk material fractions, supporting shaft with vertical axis of rotation, sieve-type drum located within casing and consisting of a number of sections, disk-type and brush cleaners positioned on the outside of drum, charging device fixed above drum, and drum rotating drive positioned within casing, under drum. Metal shaped rims are fixed to drum top and bottom. Electromagnets with cores are immovably fixed to casing of centrifugal separator, opposite rims and symmetrically relative to vertical axis of drum. Electromagnet cores are provided with cuts wherein metal shaped rims are fixed. Sieve-type drum is connected through arms and bushings with supporting shaft. Arms are connected through flexible members to carriers rigidly fixed on supporting shaft.

EFFECT: reduced frictional losses, decreased unbalanced inertial forces, low vibration loading applied to separator drive, enhanced reliability in operation of centrifugal separator, and controlled separation modes.
