北京科技大学承担研制的“七五”国家重点科技攻关项目:“湿式球磨机橡胶衬板的研究”课题,已于1990年底通过部级鉴定。湿式球磨机采用高强度、高弹性的软性耐磨橡胶衬板,在我国磨机衬板材料中是个全新的观念,改变了长期认为球磨机钢衬板“越硬越好”的传统观念。工业试验和生产实践证明:在保持高锰钢衬板球磨机相同的磨矿 Beijing University of Science and Technology undertakes the “Seventh Five-Year” national key scientific and technological project: “wet ball mill rubber liner” project, at the end of 1990 passed the ministerial level appraisal. Wet ball mill with high strength, high flexibility of the soft wear-resistant rubber liner, liner material in our country is a new concept, changing the long-term think of the ball mill steel liner “as hard as possible,” the traditional concept. Industrial trials and production practices have proven that the same grinding of the high manganese steel liner mill is maintained
