我矿选矿用水是酸性较大的循环水(pH=3.5),对跳汰机浸蚀严重,其锥体部分更为厉害,一般仅使用六、七个月。 能不能对跳汰机进行改革,使它具有耐酸腐蚀性能呢?工人们在毛主席的哲学思想的指引下,大胆试验,根据水泥有耐酸耐磨的性质,就在锥体部分的内壁上焊上一层凸形铁线网,抹上一层十多毫米厚的水泥,再涂上一层防腐船底漆。生产使用证明,水泥跳汰机的锥体部分使用寿命提高了,可用到一年左右,机体其他部分浸蚀坏了,但锥体部分的水泥层仍保持完好。同志们从此得到启发,提出试制钢筋水泥跳汰机的建议。 在试制使用水泥跳汰机的过程中,包括试制,推广使用小型水泥跳汰机和试制、推广使用大型水泥跳汰机的四个阶段。经过一段时间的奋战,第一台水泥跳汰机制造出来了,并用于生产,操作工人反映很好,选矿性能与钢制跳汰机的一样,漏水现象少了,设备运转率也有提高。我们总结第一台水
Mine mineral processing water is more acidic circulating water (pH = 3.5), jig corrosion serious, the cone part of the more powerful, usually only six or seven months. Can the jig be reformed so that it has acid-fast corrosion resistance? Workers, under the guidance of Chairman Mao’s philosophical thinking, boldly tested the properties of acid-resistant and wear-resistant cement on the inner wall of the cone Put a layer of over ten millimeters thick cement on the upper layer of convex wire netting and apply a layer of anti-corrosion ship primer. Production proved that the life of the cone part of the cement jig has been improved. It can be used for about one year. The other parts of the body are eroded badly, but the cement layer of the cone part remains intact. Since then, comrades have been inspired to put forward the proposal of trial production of reinforced cement jig. In trial production of cement jig in the process, including trial production, the promotion of the use of small cement jig and trial production, the promotion of the use of large cement jig four stages. After a period of fighting, the first cement jig was made and used for production. The workers responded well and the dressing performance was the same as that of the steel jig. There was less water leakage and the equipment operation rate was also improved. We conclude the first water
