The application is suitable for the technical field of
mineral flotation, and provides a micro-fine mineral
particle separation device, which comprises a bottom box and a top shell, a synchronous stirring mechanism is rotatably installed on the bottom box and the top shell, mineral,
water flow and flotation
reagent entering the bottom box are mixed, an
aeration unit injects gas into liquid in the rotation of the synchronous stirring mechanism, an overflow defoaming mechanism is installed on the outer side of a stirring shaft and is slidably connected with the inner wall of the top shell, an output
pipe extends into a side box, one end of a flow control ejection mechanism is in transmission connection with the synchronous stirring mechanism, the inner side of a conveying and
drying mechanism is provided with a
drying plate to dry
mineral particles in transportation, and a scraper on the outer side of the side box is in
abutment with a conveying belt; the device can improve the contact frequency of particles and floating bubbles, more
mineral particles float to the water surface per unit time, the separation efficiency of
mineral particles is improved, blockage is avoided during separation rotation, water contained in mineral particles is quickly removed, and automatic conveying and collecting work is realized.
