上海钛白粉厂的4R雷蒙机是一种粉碎矿砂的专用设备,车间内布置了两台(包括配套用风机)。矿砂经提升机进入机内,粉碎后由抽风机抽出送入下料间。工作时机内有四只约10公斤重的铁锤撞击壳体,把矿砂敲碎。因无任何隔声措施,工人操作岗位暴露在强声场中,工人对噪声反映很大。离该车间20公尺处有一小学,强烈的噪声,造成了严重的影响。同时进出料,加工均在一起,造成车间内矿粉飞扬,也造成了厂区环境污染。为此,对雷蒙机噪声和灰尘进行了综合治理。
The 4R Raymond machine at Shanghai Titanium Dioxide Factory is a special equipment for crushing ore. There are two workshops in the workshop (including supporting fans). Ore into the machine by the elevator, crushed by the exhaust fan into the next room. There are four about 10 kilograms of hammers hit the shell during the working hours to crack the ore. Due to the absence of any sound insulation measures, the workers are exposed to strong sound field in the operation post, and the workers reflect a great deal of noise. There is a primary school 20 meters away from the workshop, with strong noise and serious impact. At the same time out of materials, processing are together, resulting in the workshop flying powder, but also caused the plant environmental pollution. To this end, a comprehensive management of Raymond machine noise and dust.
