flotation machine

JJF-20 flotation machine was produced in China is the largest mechanical agitation-type flotation machine. Its structure and the United States Weimuke (WEMCO) flotation machine similar.
This flotation machine by the impeller (Star Ferry), stator, dispersion enclosures, vertical tubes, spindle and bearing components. In the bottom of the flotation machine installed at the end of the diversion of the device.
Impeller agencies flotation machine is a key component.
Impeller for astrocytes, the eight radial blades, blade 700 mm high, has a diameter of φ700 mm.
Cylindrical for the stator, there are many surrounding cylinder oval hole, there are prominent ribs.
Dispersion enclosures for the latest cone, cone angle of 90 degrees, the surface uniform circular holes.
Erected on the air intake tube, the air entering the cylinder shaft impeller chamber and pulp mixed.
Diversion devices in the false bottom of the center, its rings and adjust the bottom of the impeller 40 mm mesh, at the end of a cycle of false hole, used for pulp cycle.
The working principle: rotating impeller in the stator, adjacent to a pulp liquid vortex, a vacuum, and air from the vertical tube covered with the introduction of suction hole at the same time, pulp from the bottom up through the diversion into the leaves of space, and mixed with the air inhaled by the centrifugal impeller, the impeller blades leave the three-phase mixture through the surface of cylindrical stator fixed channel and dispersed uniformly distributed holes into the flotation, the flotation in the separation process This completed, returned to the bottom of recycled pulp mineralization bubble bubble zone rose to a foam scraps from the scraper product (concentrate or middling).
Flotation machine of this type has the following characteristics:
(1) It is the structure of inspiratory mechanical agitation, enough to self-absorption of the air, stirring relatively strong capacity.
(2) there is a relative stability of the separation zone, the mine surface stability.
(3) the gap between the impeller and the stator larger (230 mm), low-speed impeller circumference (6.6 m / sec), which would reduce the stator and the impeller wear, and lower power consumption.
The flotation machine main shortcoming is not self-absorption pulp is gravity-Ore. When the number of slot allocation at the trough of more than six, then a ladder configuration, the need to return to the bubble in the mine pumps.
The aircraft widely used in molybdenum ore processing equipment, the election lead-zinc mine equipment, copper ore beneficiation process.
