The Fagergren Flotation Machine has been placed on the market by the American Cyanamid Company. It consists of a cell of unit construction containing a stator and a rotor a complete machine being formed by mounting the required number of units in series.
The feed enters the cell through a circular port in the bottom and is drawn up into the rotor by the action of the lower impeller the suction exerted by the upper impeller draws air down into the pulp at the same time. The combined effect is to force the aerated pulpthrough the rotor and stator into the outer zone. The rapid compression and expansion of the mixture as it passes through the spacing bars produces intense agitation and very thorough aeration.

The horizontal direction of the stream of pulp issuing from the rotor combined with its very thorough aeration makes it possible to maintain a shallow pulp column in a wide cell resulting in a lower power consumption than is normally obtainable in a machine of the mechanically agitated type. The consumption seldom exceeds 2 kilowatt-hours per ton and is often considerably less.
A typical round Fagergren flotation machine is shown in the drawings having a flotation chamber 1 provided with a standard Fagergren squirrel cage rotor and stator 2 pulp inlet 4. and tailings outlet 5 and a circular froth launder 3. The rotor is driven by the shaft 6 by means of the pulley 7 from a source of power not shown.

The rotor revolves in a stationary iron cylinder which is lined on the inside with hard rubber. The combination forms a very powerful screw pump when the rotor is turned at a high speed in the direction necessary to draw pulp in at the bottom of the cylinder and discharge it at the top. The helices are given an increasing lead upwards in order to allow the pulp to expand and draw in air through the vertical slots from the hollow shaft which is closed at the bottom but is fitted with an air-regulating valve at the top designed to give accurate control of aeration.
The upper end of the rotor and stationary cylinder are overhung by a bell-shaped hood bolted to the ball-bearing assembly. The hood which is rubber-lined is open at the bottom and has a series of baffles cast on the inside to break up any whirl that the rotor may impart to the pulp.
Mar 01 1977nbsp018332The history of flotation machine design is essentially an account of the development of the impeller-stator assembly especially its aeration capacity Harris and Lepetic 1966 Harris 1974 1976b. About a dozen designs are current throughout the world while even more are obsolete.
This invention relates to aerating machines more particularly aerating machines for the flotation of ore pulp. In my prior copending applications Serial No. 498732 filed November 28 1930 and Seri Aerating machine - William Fagergren
For gas absorption the equipment possibilities are generally packed columns plate distillation towers possibly with mechanical agitation on every plate deep-bed contactors bubble columns or sparged lagoons and mechanically agitated vessels or lagoons. Packed towers and plate distillation columns are discussed elsewhere. Generally these devices are used when a relatively large number of stages more than two or three is required to achieve the desired result practically.
Dec 18 2018nbsp018332Mechanically agitated surface aerators such as the Wemco-Fagergren flotation unit Fig. 14-102 are used extensively for ore flotation. To produce foam in batch processes mechanical agitators are used almost exclusively.

In most cases available methods are incomplete or unreliable and some supporting experimental work is necessary followed by scale-up. The methods given here should allow theoretical feasibility studies help minimize experimentation and permit a measure of optimization in final design.
The induced air flotation machine was invented by William Fagergren in the 1930s in the Salt Lake Valley of Utah. Induced air means that the rotor for the froth flotation machine draws in.
