【第 1 段建议】: 1. "lmpact" 应为 "Impact" (字母o和数字1混淆) 2. "EPCO" 可能需检查是否为 "EPC" (请确认缩写的正确性) 3. "Semi-mobile" 应为 "Semi-Mobile" (统一大小写) 4. "Home > blogs" 中的 "blogs" 应为 "Blogs" (统一大小写) 请检查以上问题。 --- 【第 2 段建议】: 1. "1Stone" should be "1 Stone" (missing space). 2. "Equipments" should be "Equipment" (incorrect plural form). 3. "2019-01-26" is missing a space after the date. 4. "A Complete Guide" could be formatted consistently with other titles without capitalization on "a" (optional stylistic change). 5. "China's i" seems cut off or incomplete. Overall, minor formatting and grammatical issues are present. --- 【第 3 段建议】: 1. "wit" 应为 "with" 2. "pur users' goal" 应为 "users' goal" 3. "emerge in endlessly" 应为 "emerge endlessly" 4. "and a wide diversity" 可以考虑修改为 "and wide diversity"（更为流畅的表达） --- 【第 4 段建议】: 1. "sandstone" should be "sandstone materials" to clarify it as a subject. 2. "ag" appears to be an incomplete word and should be checked for completion (possibly a typo). 3. "I don’t know" should be corrected to "I don't know". 4. "spec" is an incomplete word and might need to be completed based on context (possibly "especially"). 5. "the new type ore Raymond mill" should be "the new type of ore Raymond mill". 6. "which are widely used in metallurgy, chemical industry, building materials and other industries" should have a comma before "and other industries" for clarity. Additionally, the text could be visually cluttered due to the use of HTML entities and formatting tags, which should not be present in the plain text. --- 【第 5 段建议】: 1. "WhatsApp:+86 13761974616" 应为 "WhatsApp: +86 13761974616"（需要在冒号后加空格）。 2. "0086-21-58386189" 和 "0086-21-58386176" 之间未加分隔符，建议使用换行符或其他方式分隔这两个号码，使其格式更清晰。
