在磨机运转时,磨机中矿石与矿石,矿石与钢球之间互相撞击发出噪音,有经验的磨矿工可以根据磨机噪音的响度来判断磨机内的装载情况。但是1(口方)以下的噪音响度的变化,人耳是难以区分的(球磨机,工作时的噪音响度为100～110(口方))。1967年7月,我厂与北京建材设计院协作,研制成磨机电耳,利用磨机工作时声音的大小,控制圆盘给料机转数,初步实现磨
When the mill is running, the ore and ore in the mill collide with each other and the ore and the steel ball make noise. An experienced millman can determine the loading condition in the mill according to the loudness of the mill noise. However, changes in the noise loudness below 1 (mouth-square) make the human ear difficult to distinguish (ball mill, noise loudness at work is 100 to 110 (mouth)). In 1967 July, I plant and Beijing Building Materials Design Institute collaboration, developed into a mechanical and electrical ear, the use of the size of the sound when the mill work, control the number of disc feeder, the initial realization of grinding
