【摘要】 通过试验室试验 ,测取球磨机在不同矿量条件下的振动信号 ,对信号进行处理和分析 ,探讨球磨机的振动信号对矿量的敏感性。结果表明振动加剧表示球磨机内矿量减少 ,振动减弱表示球磨机内矿量增加。更多还原

【Abstract】 Experiments are performed with a ball mill under laboratory conditions The vibrational signal from the ball mill is measured under different powder filling state The sensitivity of the vibration signal to the powder filling is appraised after signal process and analysis The result obtained shows that the intensified vibration represents the decrease of powder filling in the ball mill and vice versa更多还原
