Advantages and Characteristics
Xinhai JJF flotation machine is a shallow groove type with a small impeller diameter, low speed, and low power consumption;
The clearance between the impeller and the stator is large, and the stator is a cylinder with elliptical holes, which is conducive to the mixing and dispersion of air and slurry;
The height of the stator is lower than that of the impeller, and the circulation volume of the slurry is large, up to 2.5 times;
The umbrella shaped perforated dispersion cover of the stator can separate the vortex generated by the impeller from the foam layer, so as to keep the pulp surface stable;
The circulation of slurry is large, up to 2.5 times, which is beneficial for the mineralization of minerals, pharmaceuticals, and gases;
Large inhalation volume and good dispersion effect;
Moderate mixing degree, good suspension of solid particles, no settling in the tank, no need to discharge ore when parking;
Wide range of particle sizes that can be processed, high recovery rate in mineral processing;
Mechanical stirring, self suction, cannot self suction slurry, the operation room needs to be configured in steps (with a drop of 300-400mm);
It can form a combined flotation unit with SF type flotation machine, with SF type flotation machine as the suction tank and JJF type as the DC tank.
| Working principle | Process diagram of JJF mechanical agitation flotation machine3When the JJF mechanical stirring flotation machine is in operation, vortices are generated in the vertical cylinder and guide tube, which create negative pressure and draw air into the inlet tube. The air is mixed with the slurry drawn in through the guide tube in the impeller and stator area. The slurry air mixture flow is formed by the impeller to move in a tangential direction, and then converted into radial motion by the action of the stator, and evenly distributed in the flotation tank. Mineralized bubbles rise to the foam layer and are scraped out unilaterally or bilaterally as foam products. | Technical Parameter3Model | Effective volume (m) | ) | Processing ability (m) | /min) | Impeller diameter (mm) |
