2500t/d特种水泥熟料生产线原料粉磨车间工艺设计

摘要:拟设计一条日产2500t干法白水泥生产线,设计部分重点是生料粉磨配套系统工艺设计。在设计中参考了很多国内外比较先进的大型水泥厂,用了很多理论上的经验数据。其中主要设计内容有:1.配料计算、物料平衡计算、储库计算;2.全厂主机及辅机的选型;3.全厂工艺布置;4.窑磨配套系统工艺布置;5.计算机CAD绘图;6.撰写设计说明书。

白水泥与普通硅酸盐水泥在成分上的主要区别是白水泥中铁含量只有普通水泥的十分之一左右。设计采用石灰石与叶腊石两种原料。物料平衡计算时考虑到需控制铁含量,按照经验公式(石灰石饱和系数、硅酸率、铝氧率)计算并参考其他白水泥厂,得出恰当的率值为:KH0.9、IM3.85、SM18。全厂布局由水泥生产的流程决定。设计中采用立磨粉磨系统。立磨设备工艺性能优越,单机产量大,操作简便,能粉磨料粒度大、水分高的原料,对成品质量控制快捷,可实行智能化、自动化控制等优点。设计采用窑尾废气烘干物料,节约能源。总之原则上最大限度地提高产量和质量,降低热耗,符合环保要求,做到技术经济指标先进合理。

2500t / d special cement clinker production line and supporting system for kiln grinding process design

Abstract: Designing a 2500 t/d white cement production line, which was focused on the design part of the raw material grinding design supporting system. In the design, many more advanced large-scale cement home and abroad are referenced. Main content of the design were: 1. burden calculation, the material balance calculation, calculation of reservoir;

2. The whole plant selection of main and auxiliary machinery;

3. the entire plant process layout;

4. the system grinding process kiln Arrangement;

5. computer CAD drawing;

6.writing design specifications.

The main difference in composition of white cement and ordinary Portland cement is the content of white cement in the iron was only one-tenth of the ordinary cement. Controlling the iron content was considered when calculated material balance. According to the experience formula KH, IM, SM and refer to other white cement plant, drawn the appropriate ratio value: KH 0.9, IM 3.85, SM 18. The layout of the entire plant was up to the cement production process.Vertical roller mill grinding system was used in key plant design. Vertical grinding process equipment performance was superiority, single output, easy to operate, grinding people particle size, moisture and high raw materials, finished product quality control fast and it can take advantages of intelligent and automated control.In principle, the aim of the design is increase production and quality, reduce heat consumption, be accord with environmental requirements. so, technical and economic indicators should

be advanced and reasonable.

Key words: white cement;dry production line;rotary kiln;vertical mill
