ABSTRACT:
A flotation machine is intended to carry out flotation of valuable minerals, such as coal, for example, and comprises a plurality of cells provided with pulp receiving and discharging means. Mounted in each cell above horizontal stator plates and in spaced relationship therewith are aerators. Each stator horizontal plate is formed with a central opening disposed below each aerator. Arranged intermediate the stator plates is a means for regulating longitudinal recirculating streams of pulp, and between side walls of the cell and the stator plates there are arranged means for regulating transverse streams of pulp. Each of the horizontal stator plates is formed with vertical blades arranged all around the aerator at an angle to a vertical plane passing through the center of the aerator, this angle coinciding with the angle at which the pulp is discharged by the aerator. To prevent swirls in the pulp flow under the aerator, a cruciform partition is mounted below the stator plate. In the space below an overflow weir in the upper part of the cell there are provided baffle plates arranged symmetrically at an angle relative to the longitudinal axis of the cell. The baffle plates are positioned so as to permit the angle of their inclination to the horizontal to be readily adjusted.
