摘要
分析了球磨机的驱动功率、有用功率，建立了数学模型和计算方法．并把理论值和实测值进行比较，证明有了改进磨机的传统设计方案是现实磨机节能的有效途径．
The driving and useful power of the mills are analyzed. The mathematical model and calculation method have been established. The comparison of the theory values with actual values are good, proving that improving the design method of the traditional mills is an effective way to economize energy.
