球磨机的筒体部分 学位论文.doc

摘 要 为了提高粉磨效率，满足生产工艺要求，设计了用于粉磨水泥生料的Φ2.410m球磨机的筒体部分。设计了一种开流形式能实现圈流工艺的粉磨工艺系统，选定了具有选粉作用的双层隔仓板，物料通过篦板进入双隔仓中间的空间，由扬料板收集到导料锥上，合乎要求的物料进入下一仓，粗料返回一仓继续粉磨，实现磨内自选粉的工艺过程。设计了筒体、中空轴、端盖的结构，并进行了强度校核计算，确保其长期安全可靠。对磨内衬板进行了选型设计，同时合理地选择了磨内研磨体的级配，以保证整个粉磨系统的正常生产。 本设计说明书是根据机械制造工艺专业教学委员会所制定的教学计划和教学大纲，结合所学专业的理论和实践知识，编写设计出Φ2.410m球磨机的筒体部分。本此设计有工作量大、专业知识范围广、要求高等特点，不同于前面所做的课程设计。对我们所学专业知识的一次重大考验，也是对我们参加工作之前的很好的历练。 关键词：球磨机；粉磨效率；粉磨系统；双层隔仓板 ABSTRACT In order to improve grinding efficiency and meet the demands of production technology, the cylinder part of the Φ2.410m ball mill used in grinding the raw material of cement is designed. The open-current grinding system which can achieve closed-current is designed, the double-deck separter storehouse board used to choose the balls is chose, when material passes the lean into the double-deck separate storehouse, it is collected by the cone body, partial material which is qualified enters into the next storehouse, while big material retures back till it is qualified, then the system comes ture the process of free choosing technology in the mill. The cylinder empty axle and overlay are designed, the intensity is checked, to guarantee it is safe and reliable for a long time. The liner of the mill is designed, proper grading the grinding media, so as to ensure the whole grinding system to product normally. According to the plan and didactical brief made by machine manufacturing craft professional committee, this design have mainly compiled and engine case designed teaching technics regulations and multi-axis power using professional theory and practical knowledge. This design is not only a great challenge, but also a good exercise for our graduate. It has enhanced our lever of specialty, it also has cultured our team sprint at the same time. Key words: boll mill, grinding efficiency; grinding system; double-deck separate storehouse board 目 录 摘 要 Abstract II 前 言 1 1 粉磨工艺系统 3 1.1 粉磨 3 1.1.1 粉碎的意义及分类 3 1.1.2 粉碎比及粒度表示 4 1.1.3 物料的易碎性和易磨性 5 1.
