摘　　要：为了优化塔磨机的能耗,使用TM200-2.2型塔磨机对经高压辊磨后的某铁矿进行了试验,以磨后新生成的-74μm粒级产品所需能量作为能耗优化的评估标准,利用单因素试验和响应曲面法研究了介质填充率、料球比以及搅拌器转速等因素对新生成的-74μm粒级产品能耗的影响。试验结果表明:单因素试验优化的介质填充率为70%,料球比为0.20,转速为350 r/min,新生成的-74μm粒级产品的能耗为22.89 (kW·h)/t;通过响应曲面法优化的介质填充率为70.75%,料球比为0.20,转速为370.03 r/min,新生成的-74μm粒级产品的能耗预测值为21.59 (kW·h)/t,验证试验的平均值为21.61 (kW·h)/t,与预测值非常接近;采用响应曲面法优化,相比单因素试验优化后的能耗降低了5.33%。In order to optimize the energy consumption of the tower mill,the TM200-2.2 tower mill is used to test an iron ore after high pressure roll grinding.The energy required for the newly generated-74μm grade product after grinding is used as the evaluation standard for energy consumption optimization.The ef-fects of medium filling rate,material-ball ratio and agitator speed on the energy consumption of the newly generated-74μm grade product are studied by single factor test and response surface method.The experi-mental results show that the medium filling rate optimized by single factor test is 70%,the ratio of material to ball is 0.20,and the rotation speed is 350 r/min,the energy consumption of the newly generated-74μm grade product is 22.89(kW·h)/t.The medium filling rate optimized by the response surface method is 70.75%,the material-ball ratio is 0.20,and the rotation speed is 370.03 r/min.The predicted energy con-sumption of the newly generated-74μm grade product is 21.59(kW·h)/t,and the average value of the veri-fication test is 21.61(kW·h)/t,which is very close to the predicted value.The response surface method is used to optimize the energy consumption,which is 5.33%lower than that of the single factor test.
