φ3000×9000圆筒混合机筒体断裂分析与改造

Analysis and Improvement of Phi 3000×9000 Cylinder Mixer Cylinder Fracture

圆筒混合机是烧结生产工艺中的重要设备,承担着对混合料进行润湿、混匀及制粒的重任。使混合料的水分、粒度、料温及混合料的成分均匀分布并制粒,是为烧结机提供适宜混合料的关键环节。本文主要论述了莱钢股份炼铁厂2台φ3000×9000圆筒混合机筒体断裂事故分析,在综合分析的基础上进行技术改造,延长了设备使用寿命,使经济效益显著增加。

The cylinder mix machine is the importantequipment in sintering production. It plays an important roles ofmixed material wetting, mixed evenly and granulating the task.The mixture of water, particle size, material temperature andmixture of uniform composition distribution and granulation iswhether or not suitable for sintering machine with the key link ofthe mixture. This paper focuses on the shares of the ironmakingplant of Laiwu Iron and Steel Group 2 Phi × 3000 9000 drummixer cylinder body fracture accident analysis, on the basis ofcomprehensive analysis of technological transformation, prolongthe service life of equipment, economic benefits is remarkable.
