【第 1 段建议】: 1. "lmpact" should be corrected to "Impact" (capital 'I' instead of lowercase 'l'). 2. "Home > Blog > The Maintenance of Raymond Mill" should have a space after "Mill" in the last instance of "Mill" for consistency with the heading format. (Note: If the '201' at the end is intended as a header, it should be clear if it should be formatted consistently or does it need correction.) --- 【第 2 段建议】: 发现的问题： 1. "raymond mill" 应为 "Raymond mill" （首字母大写）。 2. “make the raymond mill works well” 应为 “make the Raymond mill work well” （动词形式）。 3. "the operator must carry out the necessary technical training to understand the principle performance of the mill and familiar with the operating procedures" 应为 "the operator must carry out the necessary technical training to understand the principle performance of the mill and be familiar with the operating procedures"（缺少 "be"）。 4. “it should be repaired and repaired” 应为 “it should be repaired” （重复用词）。 5. "see if it is checked" 应简化为 "see if there is any looseness" 或类似表达（用词不当）。 6. “the rolling bearings in the roller sleeve must be cleaned” 应为 “the rolling bearings in the roller sleeves must be cleaned” （复数形式）。 7. "the cleaning bearing and the bearing chamber shall be removed and cleaned once" 应为 "the cleaning bearings and the bearing chambers shall be removed and cleaned once" (复数形式)。 8. "the blower bearings are added once a month" 应清楚指定为 "the blower bearings are lubricated once a month"（用词不当）。 其余部分无错误。 --- 【第 3 段建议】: - “Demand(multiple):” 中的括号应为“Demand (multiple):” - “Materials (brochures, catalogs）” 中的右括号应为“Materials (brochures, catalogs)” - “WhatsApp:+86 13761974616” 应在“WhatsApp:”和电话号码之间添加一个空格，即“WhatsApp: +86 13761974616” - “Sales Hotline: 0086-21-58386189” 和 “0086-21-58386176” 之间应添加一个换行符或标点以更好地区分这两个电话号码。 其余内容无错误。
