FIELD: process engineering.
SUBSTANCE: invention relates to concentration of minerals. Proposed device comprises vessel with grate for magnetite suspension to be fed thereon with its bottom part connected with pump suction pump. Note here that vessel features contraction at its bottom. Besides, vessel accommodates coal loading vertical tube with its top secured at said grate and bottom arranged between tube and vessel wall to make a clearance there between. Vessel has top cylindrical part, its conical part being connected with smaller-diameter bottom cylindrical part accommodating vertical tube bottom. Note also that vessel bottom is connected with hatch.
EFFECT: uniform mixing before feed into dressing unit.
