摘要
按照系统能耗最低原则,研究了冀东鞍山式磁铁矿石粉碎过程包括爆破、破碎、磨矿作业作为一条作业线,构建了矿石粉碎过程各工艺环节能耗合理分布模型。运用该研究成果,对马兰庄铁矿的爆破、碎矿、磨矿等作业的能耗分布进行优化分配,适当提高能量利用率较高的爆破、碎矿作业的能耗,降低能量利用率较低的磨矿作业的能耗,使矿石粉碎总成本下降了4.01元/t(原矿),每年节省费用721.8万元,节能降耗效果显著。
An operation line for Anshan-type magnetite in the east of Hebei Province was studied and the line＇s comminution process included blasting, crushing and grinding. According to minimum energy principle of the system, an energy rational distribution model for processes of ore comminution was established. The model was used to optimize energy distribution of blasting, crushing and grinding processes of Malanzhuang Mine. If the energy for blasting operation and crushing operation can be increased properly and the energy for grinding operation can be decreased, total costs for ore comminution can be reduced by RMB 4.01yuan/t （run-of-mine ore） and expenses of 7. 218 million yuan are saved annually. The effects of energy saving and consumption decreasing are obvious.
