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

FIELD: mining industry; devices for the minerals concentration.

SUBSTANCE: the invention is pertaining to the field of the minerals dressing, in particular, to the apparatuses for gravity concentration and may be used for extraction of the useful component from the different grainy materials. The vibratory concentrator includes the box, the vibration exciter, the concentration component made in the form of transversal ribs and the longitudinal groove. The transversal ribs have the rake in the direction of the longitudinal groove. The ribbed coating of the concentration component is made wear-resistant. At the outlet end of the longitudinal groove there is the mounted concentrate-receiver. The box and the concentration component have the capability to change the frequency and the amplitude of the vibration. The transversal ribs of the concentration component are made in the form of two mirror-facing each other semicylinders of the bigger and smaller diameter and tightly connected to each other by their lower edges and so forming the tubular cavities with the slit inlets inside the cavities from the side of charging the vibratory concentrator. The upper edges of the neighboring semicylinders of the smaller and bigger diameter are tightly linked among themselves from their outer sides by the inclined plat. The semicylinders of the tubular cavities are rest upon the frame with the lengthwise ribs, between which in the middle part of the frame there is the lengthwise groove. The cross-cut ends of the semicylinders of the tubular cavities are tightly densely are attached to the lateral vertically disposed walls. The lower part of the lateral walls from the side of the lengthwise groove is made hinged with the capability of the periodical opening of the tubular cavities in the internal cavity of the lengthwise groove. The technical result of the invention is the raise of the efficiency of concentration, and also the improved conditions of separation of the mineral mixtures.

EFFECT: the invention ensures the increased efficiency of the mineral concentration and the improved conditions of separation of the mineral mixtures.
