FIELD: devices for separation of solid materials by means of liquid with employment of agitators and use of impulses produced by water, applicable for effective concentration of heavy minerals of fine fractions. SUBSTANCE: device has the shape of a trough with an oval bottom hinge- suspended in four points on two ropes passed over two pulleys that are arranged in the same horizontal axis along the trough center line. The trough is installed for rotation on rubberized rollers located on each side of the rotation surfaces of the trough bottom. The device has a flow of liquefied heavy medium that liquefied by supply of water from pipe connections located tangentially to the trough working surface. The rocking drive looks like an eccentric link. EFFECT: separation of minerals according to density and production of concentrate of extra fine fractions of minerals. 2 dwg
