| 摘 要： | 分析了钢球磨煤机噪声产生的原因，提出将泡沫铝应用在磨煤机隔声罩中的观点，建立了泡沫铝-玻璃棉-钢板层合板的吸声系数数学模型，并对其数值计算。结果表明，用泡沫铝取代目前磨煤机隔声罩中的阻尼层和护面层可提高隔声罩的降噪性能，且提高其环保性能。

| Abstract: | The causes of ball mills noise are analyzed. A view of application aluminum foam to the ball mills acoustical enclosures is proposed. Mathematical model of sound absorption coefficient of aluminum foamglass wool-steel laminated structure is established. And its value is calculated. The results indicate that replacing the damping layer and surface layer of the current ball mills acoustical enclosures with aluminum foam can improve noise reduction performance of acoustical enclosures,with the environmental performance improved. |
