我厂的浮选柱,过去用苧麻袋做充气器,新袋安装后三十天左右就得刷洗一次,三个月就得更换新袋,否则就会影响生产指标,使生产不能正常进行。因此,研究改进浮选柱的充气装置,就成为我厂当务之急。去年下半年,三结合试验小组,首先试用透气性较好的微孔塑料管做充气器,安装 I plant the flotation column, the past used ramie bag inflator, the new bag about 30 days after installation have to brush once, three months have to replace the new bag, otherwise it will affect the production targets, so that production can not be normal. Therefore, research to improve the flotation column inflatable device, it has become my top priority. The second half of last year, the three combined test group, the first trial of microporous plastic tube better aerator, installation
