球磨机在运转时产生噪声的大小能比较敏锐地反映负载量的大小。因球磨机滚筒内装载的矿石对钢球来说在转动时产生的噪声较小,且对钢球的撞击起着缓冲作用,故致使矿量增加到发生“胀肚”时,声音变小。而当矿量减少到出现“空砸”时,声音反而增大。使用声电变送器将检拾的噪声转换为标准电信号,就可以达到检测及控制球磨机自动给矿的目的。 Ball mill noise generated during operation can be more sensitive to reflect the size of the size of the load. Due to the ball mill drum loaded ore on the ball in the rotation of the smaller noise generated, and the impact of the steel ball plays a buffer role, it caused the mine to increase the amount of “bloating”, the sound becomes smaller. When the amount of ore reduced to “empty drop hit”, the voice increased. The use of acoustic transducer will pick up the noise converted to a standard electrical signal, you can achieve the purpose of detecting and controlling the ball mill automatically to the mine.
