近来,球磨机磨矿过程的测音调节法获得了广泛应用。然而实践表明,整个机组在启动之前和工作过程中进行调整是极为困难的,而其质量则决定着自动化的成效。众所周知,即使测音调节系统已被调整得很好,但其工作也是不稳定的,其原因之一可能是测音发送器(集音器)无根据的选择和不妥当的布置。将集音器(麦克风)最好极为接近球磨机胴体的意见是可行的。按此种方法 Recently, the ball mill grinding process of sound adjustment method has been widely used. However, practice shows that it is extremely difficult to adjust the entire unit before and during work, and the quality of the unit determines the effectiveness of automation. It is well-known that one of the reasons for this may be unsurprised choice and improper placement of the sounding transmitter (sound collector), even though the sound tuning system has been fine tuned. It is possible to have the sound collector (microphone) as close as possible to the ball mill body. Press this method
