一、建议的提出选矿厂磨矿介质材料消耗,在选矿生产成本构成中占有重要位置,一般占选矿成本的10～2O％,对个别难磨矿石可占25％以上。因此研制和采用新型耐磨材料,代替传统使用的锻钢球和铸钢球,以节省生产费用,在双增双节的时期,更有其现实意义。 First, it is proposed that the consumption of grinding media material in the concentrator occupies an important position in the cost of beneficiation production, which generally accounts for 10% to 20% of the cost of beneficiation and 25% or more for individual refractory ores. Therefore, the development and application of new wear-resistant materials, instead of the traditional use of forged steel balls and cast steel balls, in order to save production costs, double double-double period of more practical significance.
