以下是文案中的拼写错误、单复数误用及标点错误： 1. **“semi mobile”** --> “semi-mobile” (需要加连字符) 2. **“The crusher and the belt conveyor on which are integrated, occupying a smaller space.”** --> 应改为 “The crusher and the belt conveyor, which are integrated, occupy a smaller space.” (不定式短语的结构不正确) 3. **“life-cycle Service”** --> “Life-cycle Service” (首字母应大写以保持一致性) 4. **“service Localized Service”** --> “service, Localized Service” (缺少逗号) 5. **“contact home business”** --> “Contact Home Business” (首字母应大写以保持一致性) 6. **“that meet specific user requirements, with capacities ranging from 50 to 450t/h”** --> 应加“t/h”后面的空格为“50 to 450 t/h” (单位应与数字分开) 7. **“Coarse Crushing Plant Medium & Fine Crushing Screening Plant”** --> 应在“Plant”后加标点符号，如“Coarse Crushing Plant, Medium & Fine Crushing Plant, Screening Plant,” (缺少标点符号，建议使用逗号分隔) 请根据以上列出的错误进行相应修改。
