含贵金属渣浆泵矿石浮选设备
49贵金属浮 选时常用的浮选设备有哪些?
    浮选机是完成浮选过程的主要设备。浮选机应具备工作连续、可靠、电耗少、耐磨、构造简单等良好机械性能，并具有充气作用、搅拌作用和调节作用的专门功能。
    浮选机根据充气方式不同，基本上分两大类:机械搅拌式和压气式。机械搅拌式浮选机通过叶轮(或棒轮)快速回转搅拌矿浆，利用负压从槽底部吸入外部空气对矿浆进行充气。压气式浮选机无机械搅拌装置，由安装在槽下部的渣浆泵充气器引入压力空气对矿浆充气并进行搅拌。

Ore flotation equipment with precious metal slurry pump

49 what are the commonly used flotation equipment for precious metal flotation?

Flotation machine is the main equipment to complete the flotation process. The flotation machine shall have good mechanical properties such as continuous operation, reliability, low power consumption, wear resistance, simple structure, and special functions of inflation, agitation and regulation.

Flotation machines are basically divided into two categories according to different charging methods: mechanical agitation type and air compressor type. The mechanical agitated flotation machine can rotate and agitate the pulp quickly through the impeller (or the rod wheel), and use the negative pressure to inhale the external air from the bottom of the tank to inflate the pulp. There is no mechanical stirring device in the air compressor flotation machine. The pressure air is introduced into the aerator of the slurry pump installed at the bottom of the tank to inflate and stir the slurry.
