基本控制措施 主要可采取降低破碎機噪聲與建立隔聲問的方法。
降低破碎機噪聲可采取下述措施：(1)在出料口裝置消聲通道，防止內(nèi)部噪聲向外輻射；(2)在破碎機和支承結(jié)構(gòu)之間安裝具有高度內(nèi)摩擦的材料作為襯墊，以減少振動的傳遞；(3)在所有破壞物料撞擊處加裝耐磨的橡膠作為襯板；(4)對破碎機旋轉(zhuǎn)零件仔細(xì)進行平衡，減小圓錐軸套和偏心軸間隙，以降低振動強度；(5)給料板和進料漏斗的傳動表面與機架外殼覆蓋阻尼材料，減少噪聲的輻射面積；(6)破碎機安裝在防振基座上。采取上述措施后，破碎機整機噪聲可降低約15～25dB(A)。
建立隔聲間。為操作工人建立隔聲操作間，或?qū)⑵扑闄C所在局部車間改造為簡易隔聲間。前者適用于破碎機廠房與其他廠房相距甚遠，對周圍其他人群影響不大和較難于使用降低破碎機本身噪聲措施的情況。
Basic control measures can be taken to reduce the noise of the crusher and the establishment of sound insulation method.

With the surface of the rotating is arranged between a muffler device reduce the crushing machine noise can take the following measures: (1) in the discharging port of the channel, to prevent the internal noise radiated outward; (2) in the crushing machine and supporting structure with a high degree of internal friction material as the liner, in order to reduce the vibration transmission; (3) in all breaking bad impact of materials is installed at the wear-resisting rubber lining board; (4) on the crusher parts carefully balance, reduce cone sleeve and the eccentric shaft are in clearance, in order to reduce the vibration strength; (5) to the plate and a feeding funnel transmission rack enclosure cover damping material, to reduce noise radiation area; (6) crusher mounted on anti vibration base. The noise of the crusher can be reduced by about 15 ~ 25dB (A).

Sound insulation room. For the operation of workers to establish sound insulation operation, or the local workshop of the crusher is transformed into a simple sound insulation room. The former can be used in the workshop of the crusher and other factories. It has little influence on the other people. |
