【第 1 段建议】: 1. "lmpact" 应为 "Impact"（字母 “l” 应为大写字母 “I”）。 2. “EPCO” 应大写为 “EPCO”的全称（如果是缩写，需要解释说明）。 其他方面无错误。 --- 【第 2 段建议】: 1. "Calcium carbonat" should be "Calcium carbonate." 2. "raymond mills" should be "Raymond mills." 3. "Plastics" should be "plastics" (consistent with lowercase usage in the rest of the text). 4. The phrase "80-1200" is unclear; it may need clarification (e.g., "80 to 1200"). 5. The range "0.5 to 100,000" needs clarity on the units (e.g., "0.5% to 100,000 CNY"). 6. "A 400-mesh calcium carbonate mill" might be clearer as "A mill that processes 400-mesh calcium carbonate." 7. "due to the production line" could be more clearly tied to the preceding or following sentence. 8. "and the dus" at the end of the text appears to be an incomplete word or sentence fragment. --- 【第 3 段建议】: 1. “and the environmental protection effect is remarkable.” - “environmental protection effect” is awkward; consider revising for clarity. 2. “the advantages of energy saving, environmental protection and intelligence.” - Consider adding a comma before "and" for clarity: "energy saving, environmental protection, and intelligence." 3. "low cost investment" - Missed hyphenation: “low-cost investment.” 4. "short return period" - Consider specifying "short return on investment period" for clarity. 5. "Demand(multiple):" - Space needed after "Demand." 6. "Materials (brochures, catalogs）" - Use a standard closing parenthesis instead of a right bracket: "Materials (brochures, catalogs)." 7. "Our Agent" - Should be “to be our agent” for consistency with other items. 8. "SBM Blog Stone Crusher In Ethiopia" - Consider capitalizing consistently: "SBM Blog: Stone Crusher in Ethiopia." 9. "Contact Us" - Should be consistent with capitalization in “Contact us.” 10. "Copyright © 2026" - Year should be corrected if the current year is 2023 (assuming the text is updated to 2023). 11. "WhatsApp:+86 13761974616" - Space needed after “WhatsApp:” 12. "Contact Us" - Should also be consistent with capitalization in "Contact us." Please review these suggestions for clarity and consistency.
