Both XHF and BSF flotation machines are pneumatic mechanical agitation flotation machines. Both flotation machines are deep trough flotation machines, of which XHF flotation machine is “Xin Haifu (selection machine)†The first pinyin letters of the three Chinese characters are the products developed and produced exclusively by Xinhai Mining Machinery Co., Ltd., and have been declared national patents. The XHF flotation machine has self-priming slurry capacity, horizontal configuration, no foam pump, large impeller diameter and high spindle speed. The BSF flotation machine can be used alone to form a flotation system with a step arrangement; in combination with the XHF flotation machine, a horizontally arranged flotation system can be formed; the impeller only functions to agitate the slurry, recycle the slurry and disperse the air; the impeller has a small diameter The circumferential speed is low, and the gap between the impeller and the stator is large, which reduces the wear of the impeller and the stator. The impeller structure and the blade clearance flow channel are designed reasonably, the impeller wear is relatively uniform, and the impeller and stator have a long service life.
The technical parameters of the XHF type and BSF type flotation machines are listed in Tables 1 and 2, respectively.
