【第 1 段建议】: 1. "lmpact" should be corrected to "Impact" (the letter 'l' should be 'I'). 2. "lifetime" in "Life-cycle Service" is incorrectly hyphenated; it should be "Lifecycle Service" or "Life Cycle Service" (depending on the preferred style). 3. "It saves resources and protects the environment" should be made clearer, as the original sentence lacks an article (note: this is more of a style suggestion than a strict error). The rest of the text seems to be correctly spelled, punctuated, and in proper singular/plural form. --- 【第 2 段建议】: 1. "protect environment" -> "protect the environment" 2. "chemical indus" should be corrected to "chemical industry" (the word is incomplete) 3. "a thin force" might be intended as "a minor contribution" or "a slight force" (unclear phrasing) 4. "there is also a credit for the crusher" -> "there is also credit due to the crusher" 5. "crushing operation is directly effective" should be "the crushing operation is directly effective" 6. "the most important aspect of the application of mobile crushing plants should be its application in construction waste disposal" is slightly redundant; consider rephrasing for clarity. 7. "which not only solves the problem." is an incomplete thought and should be rephrased or completed. 8. "The accumulatio" is incomplete and should be completed. Note: The "reducing the transportation cost of materials and greatly reducing the production cost. ." sentence has an extra period. Please correct these issues for clarity and grammatical accuracy. --- 【第 3 段建议】: 1. "n of garbage" - The letter 'n' seems to be a typographical error and is unclear. 2. "CIP vs. CIL: Key Differences in Gold Cyanidation Processes" - The usage of "Processes" can be left as is, but if referring to more than one process, the capitalization should be consistent throughout (i.e., either all caps or not). 3. "5 Things You Need to Know about Concrete Crusher" - Should be "Concrete Crushers" for consistency in plurality. 4. "WhatsApp" - Should be "WhatsApp:" for consistency with the presentation of other contact methods. 5. "Demand(multiple)" - There should be a space between "Demand" and "(multiple)". 6. "Materials (brochures, catalogs）" - The closing parenthesis should be changed to a correct one: ")" instead of "）". 7. "Stone Crusher In Ethiopia" - "In" should be lowercase for consistency with other titles. 8. "Mobile Crusher For Sale South Africa" - "For" should be lowercase for consistency with other titles. 9. "Parts" - It is unclear whether this is intended as a heading or part of a list without context. 10. "Copyright © 2026" - If this is referring to the current year, it should be updated to 2023. Please correct these issues.
