What effect does grinding size have on flotation?
In the case of flotation coarse particles, the exfoliation force of the ore particles is increased due to the large weight. It is necessary to: 1) use a sufficient amount of the most effective collector ; 2) increase the aeration of the slurry, cause larger bubbles, and increase the amount of micro-bubbles precipitated in the water; 3) the mixing strength of the slurry should be appropriate; 4) Appropriately increase the concentration of the slurry; 5) The scraper should be quickly and smoothly foamed.
In the flotation of very fine particles (usually referred to as less than 5-10 microns of slime), 1) due to the small mass of the slime, it is easy to adhere to the surface of the coarse particles, so that the coarseness of the coarse particles is reduced, making the selectivity 2) Because the slime is larger than the surface, they will adsorb a large amount of flotation agent in the slurry, which will reduce the concentration of the agent in the slurry, destroy the normal flotation process and reduce the flotation index; 3) due to the mine The mud has a very fine surface area, so that the surface activity is increased, it is easy to work with various chemicals, it is difficult to sort, and it has strong hydration, so that the foam is excessively stable, which causes difficulty in selecting and reduces the quality of concentrate. And reduce the fluidity and concentration efficiency of the foam product.
The mixing arm drives the mixing blade to force the mixing of the material in the tank body, the mixing effect is very strong, and the mixing quality is better.There are two steel bearing protection circles between the mixing arm and shaft.to prevent coarse sand.In the steel circles there is a airway. When certain pressure of air goes though it,a pressure protection mat will be formed between the interface of the mixing arm and shaft to prevent water and mud from close to shaft head and prolong the service life of the mixer.
