Rotor Dorr Oliver Flotation Cell Cast

The Dorr-Oliver machine is a mechanically agitated flotation cell. Two-phase (water and air) simulations are conducted for a 6 m3 model of the machine. The overall dimensions of the model are shown in Figure 1. The machine is equipped with a 6-blade rotor surrounded by a 16-blade stator. Air

Nov 10, 2018 Finally the rotor should have a long (2-3 year) service life. The cell tank design should aid the flow of the coarser solid particles toward the mechanism to assist in re-suspension. In the Dorr-Oliver design, the slurry is drawn across the tank bottom into the rotor, lifted and then expelled radially from the upper region of the rotor

The second cell was installed and tested using two forced-air designs; the Dorr-Oliver cell with a conventional bottom rotor, and the newer XCELL mechanism which has a mid-rotor design. With the first cell in service, testing of the second cell progressed on a less-urgent timetable, taking roughly five months for water and slurry testing with
