基本控制措施 主要可采取降低破碎機(jī)噪聲與建立隔聲問的方法。
降低破碎機(jī)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(jī)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(jī)旋轉(zhuǎn)零件仔細(xì)進(jìn)行平衡，減小圓錐軸套和偏心軸間隙，以降低振動強(qiáng)度；(5)給料板和進(jìn)料漏斗的傳動表面與機(jī)架外殼覆蓋阻尼材料，減少噪聲的輻射面積；(6)破碎機(jī)安裝在防振基座上。采取上述措施后，破碎機(jī)整機(jī)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(jī)所在局部車間改造為簡易隔聲間。前者適用于破碎機(jī)廠房與其他廠房相距甚遠(yuǎn)，對周圍其他人群影響不大和較難于使用降低破碎機(jī)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. |
