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

FIELD: mining engineering.

SUBSTANCE: invention relates to mineral dressing, namely, gravity dressing equipment. It can be used for extracting a valuable mineral from various granular materials. According to the invention, the vibrator concentrator has a concentration part with symmetrised transverse ribs divided into separate sectors by means of separating transverse ribs similar to the symmetrised transverse ribs, but with an inclination in a reflection similar position. In addition, the external butt ends of the separating transverse ribs are tightly connected with longitudinal walls by passages manufactured between their internal butt ends from sector to sector along the center line of the concentration part. A similar passage is also manufactured from the inlet box screened by the separating transverse ribs from the working side of the first adjacent sector. The transverse ribs located inside each sector are also tightly connected together with the separating transverse ribs by means of their internal butt ends and have a gap between their internal butt ends and longitudinal walls. Directly behind each of the separating transverse ribs on the side reverse to the one of charging, the plate is provided with slots screened by the ribs along their opposite longitudinal edge that are similar to the separating transverse ribs and by inclined walls as high as the transverse ribs on the internal butt ends. There is a slot made in the plate near the end reverse to the one of charging of the vibrator concentrator. The slot screened from the external side by a transverse vertical wall higher than the transverse ribs is for withdrawal of tails issuing over the rims of the separating transverse ribs the last from the charging side. The external ends of the last separating ribs of the vibrator concentrator are equipped with heads receptacles in a symmetric position to the longitudinal center line of the concentrating part and screened from the working side by the lateral inclined walls higher than the transverse ribs and equipped by an adjustable gap in the lower part near the plate surface.

EFFECT: more efficient gravity dressing, process specific capacity as well as improved conditions of separating mineral mixtures and continuous vibrodynamic withdrawal of high-density fractions and light fractions of a wide grain size range.
