一种药剂高效分散的矿浆预处理器
By adding a dispensing pipe to the slurry preprocessor and distributing it evenly in the circumference, a gas-liquid two-phase dispersion system is formed by the shearing action of the impeller and stator. This solves the problem of uneven reagent dispersion, improves the mixing uniformity of slurry and reagent and flotation efficiency, and reduces reagent waste.

AI Technical Summary
In existing slurry preprocessors, the contact area between the reagents and the slurry is small, resulting in a low probability of collision. This leads to poor separation performance, uneven reagent dispersion, significant waste, and low flotation efficiency.
The number of dosing tubes is increased and evenly distributed around the circumference. A four-way pipe structure is used to evenly distribute the reagent into each dosing tube around the stator. The reagent is pulverized into fine droplets by the shearing action between the impeller and the stator, forming a gas-liquid two-phase dispersion system, which increases the contact area and mixing uniformity between the reagent and the slurry.
It improves the dispersion uniformity and mixing effect of reagents in slurry, increases the contact probability between reagents and slurry, optimizes flotation effect, reduces reagent waste, and improves separation efficiency.
