冶金矿山选厂尾矿输送管道的磨蚀与堵塞 ,一直是困扰选厂的关键问题。长期生产实践表明 ,使用传统的金属管来输送尾矿 ,不仅其使用寿命短 (一般 4年左右 ) ,维修更新费用高 ,而且一旦管壁磨穿 ,矿浆泄漏 ,污染农田、自然环境 ,影响正常生产。所以 ,从 60年代以后 ,越来越多的黑 The abrasion and clogging of the tailings conveying pipeline of the metallurgical mine processing plant has always been a key issue that troubles the mill selection. Long-term production practice shows that the use of traditional metal pipe to transport tailings, not only its short life (usually 4 years), maintenance and renovation costs are high, and once the wall wear, pulp leakage, pollution of farmland, the natural environment, affecting the normal produce. So, from the 60’s later, more and more black
