摘要:
介绍了行星式球磨机的特点和研制历程.首先利用材料疲劳损伤积累理论,分析行星式球磨机的节能机理,指出其节能特性不仅与磨机状态有关,还与磨料的物理性质有关.其次,运用数理统计学概念及赫兹应力计算方法,描述了粉体应力分布、疲劳损伤积累效果以及行星效应与节能效果的关系模型.然后研究了粉体工作应力,推导出冲击能耗降低系数,定量表达了磨机的节能机理.最后以制备矿渣微粉为例比较了三类典型设备的性能,验证了理论的正确性,并指出一般情况下行星式球磨机节能约30%～40%.
Abstract:
The characteristics and the development of a new planetary ball mill are introduced. Firstly, based on the material fatigue damage accumulation theory, the energy-saving mechanism of the planetary ball mill is analyzed, which shows that the energy-saving mechanism is affected by not only the working condition of planetary ball mill but also the physical property of powder. Secondly, the mathematical statistics concepts and Hertz stress calculation method are applied to formulate the stress distribution of powder, the depletion of fatigue damage accumulation, and the relationship model between planet effects and energy-saving effect. Thirdly, the depletion efficiency of powder impact is proposed to interpret the energy-saving mechanism of the planetary ball mill. Finally, the production of slag powder is taken as an example to compare the performance of three categories of typical equipment. The experiments show that the planet ball mill can save the energy up to 30% to 40%.
