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。
Cylinder mixer is an important equipment in the sintering production process, undertaking the task of wetting, mixing and granulating the mixture. The moisture, the particle size, the material temperature and the ingredients of the mixture are uniformly distributed and granulated, which is the key point for providing suitable mixture for the sintering machine. This article mainly discusses the analysis of 2 sets of φ3000 × 9000 cylinder mixer rupture accidents in the iron and steel works of Laiwu Iron and Steel Co., Ltd., and carries out technological transformation on the basis of comprehensive analysis to extend the service life of the equipment and increase the economic benefits remarkably.
