振动筛是采矿作业中的一种主要设备。它在运行时不但产生机械噪声,而且由于铁矿石的筛分、转运和相互撞击等原因,还产生大量的粉尘,严重地污染作业环境,影响工人身体健康。为此,我们对铁矿石筛分分级用的六台偏心振动筛噪声与粉尘进行了治理。 在设计中,我们坚持了两条原则:一 Vibrating screens are a major equipment in mining operations. It not only produces mechanical noise during operation, but also produces large amounts of dust due to screening, transport and collision of iron ore, which seriously pollutes the working environment and affects workers’ health. For this reason, we have handled the noise and dust of six eccentric shale shakers for the classification of iron ore smelting. In the design, we insisted on two principles: one
