为了进一步了解自磨磨机的生产使用情况,开展自磨磨机的试验研究工作,我们进行了一次调查。从中,我们感到:干式自磨磨机风路系统中的锁气阀和管道连接法兰普遍存在着漏气现象,因而造成网路系统收集净化效率降低,网路回风气体含尘浓度增高,致使风机叶轮严重磨损和磨机产量降低。同时也造成闭路网路给矿漏斗处不能很好的形成负压,向外“冒烟”,使厂房空气中粉尘浓度增高,影响
In order to further understand the self-mill production and use of self-grinding mill to carry out the pilot study, we conducted a survey. From this, we feel that the air leakage phenomenon exists in the lock air valve and the pipe connecting flange of the dry self-grinder air duct system, which leads to the decrease of the net system collecting and purifying efficiency and the increase of the dust concentration of the return air net , Resulting in serious fan impeller wear and reduce mill output. At the same time, the closed-circuit network can not form a negative pressure to the funnel at the mine and “smoke” outward to increase the concentration of dust in the air of the plant and affect
