摘要

摘要:
针对大冶诺兰达转炉渣磨矿过程，研究了陶瓷球替换钢球对磨矿效率、能耗、物耗及分选指标等的影响。实验室实验研究表明，一段二段磨矿过程中，磨矿效率随着陶瓷球替代比例增加而降低；但陶瓷球体积比例控制在40%以内时，对磨矿效率影响较小。而采用全陶瓷球磨矿，给矿量降低到全钢球的80%，可实现与全钢球时等同的磨矿效率。工业实验研究表明，当立磨机中陶瓷球比例14%为38%时，基本不影响磨矿效率、药剂消耗及铜精矿指标，但对磨矿过程中的能耗分别降低为全钢球的89.90%和79.60%，减少了磨矿过程中介质的消耗，研究结果为转炉渣选矿厂生产过程中节能降耗提供了新思路。

Abstract:
In this paper, the effect of ceramic ball replacing steel ball on grinding efficiency, energy consumption, material consumption and separation index was studied for the grinding process of Daye Noranda converter slag. The laboratory studies presented that the grinding efficiency decreases with the increases of ceramic ball replacement ratio in the process of primary and secondary grinding, however, However, the grinding efficiency was hardly influenced when the ceramic ball volume proportion is controlled within 40%, and the ore feed need to be reduced to 80% of the whole steel ball which can achieve the same grinding efficiency as the whole steel ball in the case of all-ceramic ball grinding. The industrial test results showed that grinding efficiency, reagent consumption and copper concentrate index are not affected when the proportion of ceramic balls in vertical mill is 14% to 38%, but the energy consumption is reduced to 89.90% and 79.60% respectively of the whole steel ball during grinding, and the loss of grinding medium is reduced in this process. This The research results provide a new idea for energy saving and consumption reduction in the production process of converter slag concentrator.
