The invention is applicable to the technical field of
mineral flotation, and provides a fine mineral
particle separation device which comprises a bottom box and a top shell, a synchronous stirring mechanism is rotatably mounted on the bottom box and the top shell and is used for mixing minerals,
water flow and a flotation
reagent entering the bottom box, and an inflation unit injects gas into liquid during rotation of the synchronous stirring mechanism so that the flotation
reagent can enter the bottom box. The overflow defoaming mechanism is mounted on the outer side of the stirring shaft I and is in sliding connection with the inner wall of the top shell, an output
pipe extends into the side box, one end of the flow control ejection mechanism is in transmission connection with the synchronous stirring mechanism, a
drying plate is arranged on the inner side of the conveying and
drying mechanism and is used for
drying mineral particles in transportation, and a scraping plate on the outer side of the side box abuts against a conveying belt; according to the device, the contact frequency of particles and floating bubbles can be improved, more
mineral particles emerge from the water surface in unit time, the separation efficiency of the
mineral particles is improved, blockage is avoided in the separation and rotation process,
moisture contained in the mineral particles is rapidly removed, and automatic conveying and collecting work is achieved.
