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

FIELD: mechanics, mining.

SUBSTANCE: invention can be sued for extracting useful component from various drain-like materials. The proposed vibro concentrator concentration element with symmetric crosswise ribs is separated into isolated sectors by separating crosswise ribs arranged in symmetry to the aforesaid crosswise ribs but with an inclination arranged in mirror-like position. The symmetric crosswise ribs arranged inside every said sector are tightly connected both between themselves and with the separating crosswise ribs by means of their inner end face edges with a gap between the said edges and lengthwise walls. There are tail removal holes arranged in every sector nearby the inner and outer edges of the aforesaid separating ribs and in symmetry with the lengthwise axial line of the concentration element, the said holes being screened by the side inclined walls with the height equal to that of crosswise ribs. The inner end faces of the separating crosswise ribs and outer end faces of symmetric crosswise ribs feature a gap between them and the side inclined walls that screen the tail removal holes. The receiving box has an outlet arranged in its central part to feed the starting material into the first concentration element sector, if seen on the feed side. The starting material feed channels are arranged between the said tail removal holes screened by vertical walls with the height exceeding that of the crosswise ribs. The vibro concentrator end, opposite the feed one, is furnished with a slit-like hole to remove the tails coming out through the edges of separating crosswise ribs, the most distance from the feed side, the aforesaid slit-like hole being screened, on its outside, by a crosswise vertical wall with the height exceeding that of the said crosswise ribs. The concentrate receiving devices are arranged at outer ends of the last separating ribs, screened by the side inclined walls with the height exceeding that of the crosswise ribs and having an adjustable gap at their lower part.

EFFECT: higher efficiency of gravity concentration.
