VIBRATION CONCENTRATOR Russian patent published in 2008 - IPC B03B5/70 B03B5/02 

FIELD: mining.

SUBSTANCE: vibration concentrator includes concentration element with symmetrical transverse ridges divided into separate sectors by transverse division ridges similar to symmetrical transverse ridges, but with mirrored sloping. Transverse division ridges are connected tightly by outer ends to lengthwise walls, and symmetrical transverse ridges inside each sector are connected tightly both to each other and to transverse division ridges by inner ends and feature gap in lower part between outer ends and lengthwise walls. Holes for tail outlet are made in a plate in each sector close to inner division ridge ends symmetrically to lengthwise axial line of vibration concentrator, are screened at work side by lateral sloping walls of height equal to transverse ridge height, and feature gaps with inner ends of transverse division ridges. Feed passes to each sector are made between tail outlet holes and screened by vertical walls higher than transverse ridges. Loading plate is mounted on a plate at loading end of vibration concentrator and screened from outside by transverse vertical wall higher than transverse ridges, and from inside by transverse division ridges with outlet in middle part to first concentration element sector from loading side. Outlet hole for tails passing through edges of last transverse division ridges from loading side is made in a plate at the vibration concentrator end opposite to loading end, and screened from outside by transverse vertical wall higher than transverse ridges. Concentrate collectors are mounted at outer ends of last division ridges symmetrically against lengthwise axial line of vibration concentrator, are screened at work side by sloping side walls higher than transverse ridges, and feature adjustable gap in lower part.

EFFECT: enhanced efficiency of gravitation treatment of minerals and specific efficiency of process.
