Description

JJF series flotation machine: This type of flotation machine has a reasonable structure, stable operation and reliable performance. Its performance has reached the advanced level of foreign flotation machines and is suitable for the separation of non-ferrous, ferrous metals and non-metallic minerals. This device has the following features: self-priming air; The pulp has good circulation characteristics. The intake volume is relatively stable. The stirring intensity is moderate and the solid particles are well suspended. The liquid level is stable and the power consumption is low.

Advantages

• The flotation machine is of shallow tank type, with a small impeller diameter, low rotational speed and relatively low power consumption.
• The gap 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 pulp.
• The height of the stator is lower than that of the impeller, and the slurry circulation volume 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 slurry surface stable.
• The stirring degree is moderate, the solid particles are well suspended, do not settle in the tank, and there is no need to release ore when the machine stops.
• It has a wide range of particle sizes that can be processed and a high beneficiation recovery rate.

Working principle

When the JJF type mechanical agitation flotation machine is in operation, vortices are generated in the vertical cylinder and the deflector tubes. These vortices create negative pressure, which sucks air in through the air inlet pipe and mixes it with the pulp drawn in through the deflector tubes in the impeller and stator areas. The mixed flow of slurry and air moves tangentially by the impeller, and then is converted into radial motion by the stator, and is evenly distributed in the flotation cell. Mineralized bubbles rise to the foam layer and are scraped out on one or both sides, resulting in foam products.
