摘　　要：超细搅拌磨机是一种高效节能的超细粉磨设备,是目前制备亚微米粉体或浆料的主要设备,本文利用计算流体力学方法(CFD 法)对超细搅拌磨机进行了流场仿真数值模拟。采用不同搅拌磨机进行对比试验,结果表明棒式搅拌磨机的研磨效果较好,这与流场数值的模拟结果是一致的,验证了模型的建立和模拟分析的正确性和可靠性。并且3600L 大型超细搅拌磨机在重质碳酸钙和重晶石超细粉碎工程实践中的应用,证明这种搅拌磨机的结构设计合理,设备性能优越,具有较好的发展前景。Ultra-fine stirred mill is a kind of efficient and energy-saving ultra-fine grinding equipment, which is the main industrial equipment for submicron powder production. This paper works on the flow-field numerical simulation of ultra-fine stirred mill by computed fluid mechanics. The experimental comparison of different stirred mills shows that the grinding efficientness of rod stirred mill is better and its results accord with that of numerical simulation, and certificates the correct and reliability of modeling and simulation analysis. The application of 3600L large ultra-fine stirred mill used for ultrafine grinding heavy calcium carbonate and barite, proves that its designed structure is proper and it has high performance.
