在冶金及其他行业生产中,粗矿原料和半成品物料的细碎所用之球磨机喂料量,以往是通过人耳监听磨音强弱或凭经验观察操作的,后来又采用“电耳”(即嗽叭)监听磨音,控制下料量。但“电耳”易受工作场所周围强噪音的干扰,故信号检测可靠性差。为此我们采用了淄博无线电三厂试制的振动变送器之压电振头作为检测磨机振动元件,来实现磨机喂料自动调节。经一系列工业试验证明,效益显著。具体介绍如下。 In the metallurgy and other industries, ball mill feed used for the crushing of rough ore and semi-finished materials was traditionally used to monitor the strength of sound worn by the human ear or by empirical observation, Speaker) to monitor the grinding sound, the amount of material under control. However, “ear” susceptible to strong noise around the workplace interference, so the reliability of signal detection is poor. To this end, we use the Zibo radio factory vibration transducer vibration piezoelectric vibrating head as a test vibration components, to achieve mill feed automatically adjust. After a series of industrial tests proved that the effectiveness of significant. Specific introduction is as follows.
