充气机械搅拌式浮选机进气座的改造与应用

Modification and Application of Air Inlet seat of Aerated Mechanically Agitated Flotation Machine

充气机械搅拌式浮选机是选矿厂浮选作业的主要设备,其进气座在浮选机运行时有“摇头”现象,轴承磨损严重,使用寿命短,进气管卡顿故障频发,导致浮选机充气量不足,影响生产指标的稳定。分析引起进气座损坏的原因,介绍所采取的措施,即改造进气座的进气管结构、轴承等。改造后进气座运行效果较好,使用寿命增加,故障率较低。

The aerated mechanical stirring flotation machine is the main equipment for flotation operation in the concentrator.Its air inlet seat has the phenomenon of"head shaking"during the operation of the flotation machine.The bearing is seriously worn,the service life is short,and the air inlet pipe is stuck frequently,which leads to insufficient air charging of the flotation machine and affects the stability of the production index.This paper analyzes the causes of the damage of the intake seat,and introduces the measures taken,namely,reforming the intake pipe structure and bearing of the intake seat.After transformation,the air inlet seat has good operation effect,longer service life and lower failure rate.
