Project Context项目背景 / 01
Large Ball Mill大型球磨机
The processed section relates the feeding assembly and bearing supports to the complete mill. It provides team assembly context for the two subsystem cases.处理后的剖面将进料装配与主轴承支承联系到整机，为两个子系统案例提供团队装配背景。

A replacement large ball mill for an existing production line, designed to fit the retained foundations and installation interfaces. The complete assembly model provides the team project context; the two subsystem case studies focus on my own component design work.现有生产线的大型球磨机更新工程，设计需适配原有的基础与安装接口。整机模型提供团队项目背景，两个子系统案例聚焦个人部件设计能力。
I work on this replacement mill as part of the project team. My share is the feeding system and main bearing models and drawings, the general arrangement and foundation drawings, and the P&ID and BOM.我作为项目团队成员参与这台更新球磨机的工作，负责进料部与主轴承部的模型和图纸、整机总图与基础图，以及 P&ID 和 BOM。
Existing condition既有现场
Start from the real site.从真实现场出发
The old mill stayed in operation, so partial drawings and site measurements formed the basis of the replacement design.原设备仍在运行，残缺图纸与现场测量共同构成更新设计的依据。
Engineering Challenge工程难点
The site foundation sets the project boundary现场基础决定项目边界
The operating mill could not be fully dismantled, and the available drawings were incomplete. The replacement design therefore had to reconcile site measurements with the retained foundation, machine centerline and installation interfaces.原设备仍在运行，无法完整拆解，现有图纸也不完整。更新设计需要将现场测量与保留的基础、整机中心线及安装接口相互核对。
- Existing foundation既有基础
- Installation interfaces安装接口
- Machine centerline整机中心线
- Incomplete legacy documentation不完整的历史资料
Design basis设计依据
Relate assigned components to the complete mill assembly将负责部件联系到整机装配
Partial drawings残缺图纸
Site measurements现场测量
Confirmed interfaces已确认接口
New design basis新的设计基准
- Site foundation现场基础
- Machine centerline整机中心线
- Bearing supports主轴承支承
- Feeding interfaces进料接口
Partial drawings, site measurements and confirmed interfaces establish the team design baseline for locating the bearing supports and feeding connections within the complete mill.团队结合残缺图纸、现场测量与已确认接口建立设计基准，用于在整机中定位主轴承支承与进料连接。
Technical Evidence / Machine reconstruction技术证据 / 整机重建
The complete model provides team assembly context for my assigned component work. Explore the feeding and main bearing interfaces through the two subsystem cases.整机模型提供团队装配背景，可通过两个子系统案例进一步查看进料与主轴承接口。

Field / Design现场 / 设计
The site remains part of the design.现场始终是设计的一部分
Site inspection and measurement recovered dimensions missing from legacy documentation, verified installation interfaces and informed the replacement-equipment design.通过现场检查与测量补齐旧图纸缺失的关键尺寸，核实安装接口，将已确认现场信息反馈至更新设备设计。
