精选文档 摘要

本设计的任务要求是日产5000吨水泥熟料系统水泥磨系统工艺设计。做这个设计的主要是我们在水泥厂里实习的车间是水泥磨，设计要求我们结合自己单位的实际，来设计一套水泥磨系统

本设计通过在自己单位的实际生产中遇到的问题和系统上一些不合理的工艺生产流程，将其问题进行解决和进行改进

本次设计一个年产160万吨普通硅酸盐水泥厂水泥粉磨车间。在这次设计中，以国内外先进的生产工艺和技术装备以及经验参数为基础，以节能降耗和保护环境为原则，并结合生产实际，采用了先进和合理的生产工艺流程及设备，同时进行了合理的全厂总平面布置和重点车间布置。

本次设计生产的水泥是PO42.5。

1）5000t/d熟料的水泥厂配料设计、物料平衡计算；

2）5000t/d熟料的水泥厂设备选型计算和主机生产能力平衡计算；

3）5000t/d熟料的水泥厂水泥磨系统工艺设计说明书的编制；

4）5000t/d熟料的水泥厂工艺流程图及水泥磨系统工艺布置图设计。

关键字：水泥磨系统工艺设计，全厂总平面布置，重点车间布置，物料平衡，PO42.5

Abstract

The design of the task requirement is 5,000 tons daily production of

cement

clinker cement mill system process design system. Designed to do this mainly

because we practice in the cement plant is in the cement mill, in conjunction

with their unit design requires practical, to design a cement mill system

This design through actual production units in their own problems and

systems in some reasonable production process technology, to improve problem

solving and

The design of an annual output of 1.60 million tons of cement grinding

of ordinary portland cement plant. In this design, to advanced production

technology and technical equipment and experience parameters as the basis for

the energy saving and environmental protection principles, and actual

production, and reasonable use of advanced production process and equipment,

while for a reasonable whole plant general layout and key plant layout.

Keywords: Portland cement, dry production process, Portland cement clinker,

cement grinding, material balance
