椭圆辊辊压磨动力分析及优化设计

众所周知，水泥工业70％～80％的能量消耗在粉磨工艺上，能量利用率很低的管式球磨机一直在水泥粉磨过程中占主导地位。而传统的以球磨机为主的粉磨作业耗电量约为总耗电量的65％～70％。而球磨机的粉磨有效功仅占提供给磨机运转能量的1％～3％，能量利用率非常低。挤压磨或称辊压磨，是上世纪80年代中期发展起来的一种新型粉磨设备，是粉磨技术的突破。在水泥工业中，人们认为它是继窑外分解技术之后的又一重大技术进步。挤压磨的应用可大幅度地提高产量，降低能耗。

Dynamic Analysis and Optimization Design to the Mill with the Elliptical Roller

The paper analyses and determines the approach for optimizing the design to the parameters of the elliptical roller of the mill, and also determines the shape of the elliptical roller according to the practical application condition. In addition, it analy- ses the mechanism of the squeeze grinding with the different velocity elliptical roller and the realization approach by the theory about the roller mill, and analyses the advantage, disadvantage and practicability of different velocity squeeze grinding by applying the elliptical roller.
