雪浪采矿厂原来采用干法破碎加吸尘设备时,粉尘浓度高达183毫克/米～3,后来结合设备改造,采用冲水破碎新工艺,在加料口和振动筛上装喷水管加湿,并在出料口和机口加密闭抽风装置,抽出的含尘空气经水浴除尘器净化,终于使粉尘浓度下降到0.3～1.2毫克/米～3,而且降低了石子含泥量, Xuelang mining company originally used dry crushing and vacuuming equipment, the dust concentration of up to 183 mg / m ~ 3, later combined with equipment modification, the use of flushing new technology, feeding port and shaker mounted spray pipe humidification and In the discharge port and machine mouth closed vacuum device, the dust-containing air extracted by the water bath precipitator purification, and finally the dust concentration dropped to 0.3 ~ 1.2 mg / m ~ 3, but also reduces the amount of clay content,
