CENTRIFUGAL VIBRATORY CONCENTRATOR Russian patent published in 2009 - IPC B03B5/32 

FIELD: mining.

SUBSTANCE: centrifugal vibratory concentrator consists of a conic bowl with concentrating element in form of ribbed coating and disk secured on bottom of bowl with gap; conic bowl is designed to rotate on hollow vertical shaft; further concentrator consists of measuring hopper, of loading and unloading facilities, of device for flush water supply, of concentrate receiver, and of vibration exciter. The conic bowl with concentrating element is designed to alter frequency and vibration amplitude. The concentrating element is made in form of a truncated cone with ribs on internal surface; the ribs are inclined downward and tilted to the loading side, also there is possibility of changing number of ribs, their height and angles of incline. The concentrating element and its ribbed coating are made wear resistant. The vibration exciter is made in form of a rotary eccentric coupling of the hollow vertical shaft of the conic bowl to a driven shaft of a bearing unit. In the upper part of the conic bowl the vibratory concentrator has a circular regulated pass connecting between the ribs grooves of the ribbed coating with the internal cavity of the unloading device. The circular regulated pass is screened from above with a circular disk movably secured by the end of the conic bowl; internal diametre of the disk variates; also the disk is equipped with a shell directed downward. The shell is secured along the external edge of the disk. The cone-shaped receiver is installed inside the unloading device directly under the shell of the circular disk; the cone-shaped receiver is equipped with a branch for outlet of heavy fraction in its lower part.

EFFECT: increased efficiency of separation of valuable components, and increased specific efficiency of installation.
