FIELD: minerals concentration equipment. SUBSTANCE: apparatus has vertical shaft, perforated transfer strips, oversize and undersize product hoppers, immovable inclined screen, hydraulic classifier and jet-type hydraulic transportation device. Inclined screen is composed of two parts. Upper part is made in the form of nozzles rotating in direction opposite to direction of flow of basic material. Flexible connecting members are arranged between nozzles. Lower immovable part has cells of predetermined size. Nozzles are composed of two concentric cylindrical parts. Inner immovable cylindrical part has hermetically sealed diametrical wall. Water is supplied under pressure into upper cavity of inner immovable part and compressed air is fed into lower cavity. Inner immovable part wall is provided with openings for discharge of compressed air and water into cavity between cylindrical members. Outer rotating cylindrical part is provided with diametrically opposed nozzle openings generating water and air jets. Apparatus is used in mining, in particular, for ore washing. Apparatus allows clay association disintegration extent to be increased. EFFECT: increased efficiency and simplified construction. 2 dwg
