FIELD: enrichment of minerals. ^ SUBSTANCE: vibration concentrator comprises box, vibration exciter, concentrating member made of plates and in block with the plates of transverse ribs, and longitudinal groove with variable depth conjugated with inter-rib hollows by means of side opening. The longitudinal groove has sides provided with openings. The plate is provided with longitudinal vertical walls that are rigidly connected with the outer faces of the transverse ribs. The transverse ribs are sloping in the direction of the longitudinal groove and are inclined to the charging side. The ribbed coating of the concentration member is wear proof, the concentrator receiver is mounted at the outlet end of the longitudinal groove, and the frequency and amplitude of vibration of the box and concentration member can be changed. The bottom of the longitudinal groove is perforated. ^ EFFECT: enhanced efficiency. ^ 3 dwg
