SWIRLING STATIC COMBINED DOUBLE-SECTION TYPE FLOW FIELD FINE PARTICLE FLOTATION APPARATUS

摘要

Disclosed is a swirling static combined double-section type flow field fine particle flotation apparatus, belonging to the technical field of mineral processing. The swirling static combined double-section type flow field fine particle flotation apparatus comprises a mixing drum (2), wherein a feeding pipe (3) is connected to one side of the upper end of the mixing drum (2); a first mixing rod (6) is inserted at the upper end of the mixing drum (2), and the first mixing rod (6) is mounted to the mixing drum (2) by a bearing; a first belt pulley (1) is arranged on the first mixing rod (6), and the first belt pulley (1) is located at the upper side of the mixing drum (2); and a flow guiding drum (4), an upper high speed mixing impeller (5) and a lower high speed mixing impeller (7) are arranged at the inner side of the mixing drum (2) successively from top to bottom, and each of the flow guiding drum (4), the upper high speed mixing impeller (5) and the lower high speed mixing impeller (7) is connected to the first mixing rod (6). The invention achieves the double-section type flow field flotation separation for fine particle minerals, and changes the current situation that the flow field characteristic of the flotation apparatus is single, significantly improving a flotation recycling effect of the fine particle minerals.
