【第 1 段建议】: 1. "lmpact" should be changed to "Impact" (there is a lowercase 'L' instead of an uppercase 'I'). 2. "EPCO" should be checked for consistency; if it is an acronym, it should be verified whether it is correctly capitalized or if it should be expanded as "EPC" (Engineering, Procurement, and Construction) if it is relevant context. 3. In “3 steps to judge the service life of i,” the text is cut off and should be completed for clarity. Note: The text appears cut off at the end, which might suggest an issue depending on context. --- 【第 2 段建议】: 1. "ndustrial" 应为 "Industrial" 2. "their own service life" 应为 "its own service life" 3. "to extent the service life" 应为 "to extend the service life" 4. "user" 应为 "users" (在“user must do lubrication regularly”中) 5. "grinding rolls pressure" 应为 "grinding roll pressure" 6. "advanced manufacturing technology and superior high wear-resisting and high-quality material" 中的 "material" 应为 "materials" (与前文中的 "materials" 一致) 7. "proper grinding mill company" 应为 "proper grinding mill companies" (保持一致性) 请修正以上错误。 --- 【第 3 段建议】: 1. "you can leave a message or contact us directly hotline" - 应为 "you can leave a message or contact us directly at the hotline". 2. "5 Things You Need to Know about Concrete Crusher" - 应为 "5 Things You Need to Know about Concrete Crushers" (需改为复数). 3. "WhatsApp" - 应为 "WhatsApp". 4. "Materials (brochures, catalogs）" - 应为 "Materials (brochures, catalogs)" (右括号应为英文的). 5. "To be Our Agent" - “to be our agent” (应首字母小写). 6. "Demand(multiple)" - 应为 "Demand (multiple)" (需空格). 7. "Life-cycle Service" - 应为 "Lifecycle Service" (更常见的说法). 8. "Sales Hotline: 0086-21-58386189" - "Sales Hotline: +86 21-58386189" (加号缺失). 请根据这些建议进行相应修改。
