JJF type mechanical stirring flotation machine

Advantages and Features

• Huston jjf flotation machine has a shallow groove shape, small impeller diameter, low speed, and low power consumption
• the gap between the impeller and the stator is large, and the stator is a cylinder with an elliptical hole, which is conducive to the mixing and dispersion of air and slurry
• the height of the stator is lower than the impeller, and the slurry circulation volume is large, up to 2.5 times
• the umbrella-shaped perforated dispersion cover of the stator can isolate the eddy current generated by the impeller from the foam layer, so that the slurry surface remains stable
• The slurry circulation volume is large, up to 2.5 times, which is beneficial to the mineralization of ore, medicine and gas
• large air suction volume, good dispersion effect
• moderate stirring degree, good solid particle suspension, no sinking, no need to discharge ore when parking
• wide range of particle sizes that can be processed, high recovery rate of ore dressing
• mechanical stirring, self-priming, cannot self-prime the slurry, the operation room needs to be equipped with a ladder (the height difference is 300-400mm)
• can be used with SF type flotation machine It forms a combined flotation unit, with the SF type flotation machine as the suction tank and the JJF type as the direct flow tank.

Working Principle

When the JJF mechanical agitator flotation machine is working, vortices are generated in the vertical cylinder and the guide tube. This vortex forms a negative pressure, sucking air in from the inlet pipe, and mixing it with the slurry sucked in through the guide tube in the impeller and stator area. The mixed flow of slurry and gas is formed into tangential movement by the impeller, and then converted into radial movement by the action of the stator, and is evenly distributed in the flotation tank. The mineralized bubbles rise to the foam layer, and the foam product is scraped out from one or both sides.

Case Study

Huston conducted a beneficiation test for a certain copper mine. The flotation equipment selected was a jjf-type flotation machine. In the design, 24 jjf-16 flotation machines were selected, 6 of which were in a series. In order to test the processing capacity of the flotation machine, two flotation machine series and parallel tests were conducted. Finally, after two sets of multiple tests, Huston chose the flotation machine series method for this copper ore dressing plant: two pairs of ball mills were turned on, the ore processing capacity was 110t/h, and the slurry volume was 285.52m 3 /h. At this time, the liquid level and foam volume in the jjf flotation machine tank were moderate, and the flotation scraping was normal.
