【第 1 段建议】: 1. “Jaw Crusher Components & Parts III” 中的 “Parts” 应为 “Part”，因为后文只提到 “Jaw Crusher Components & Part”。 2. “Vertical Shaft lmpact Crusher” 中的 “l” 应为 “I” 应为大写字母I（即 “Vertical Shaft Impact Crusher”）。 --- 【第 2 段建议】: 1. "will fix and reduce the load coefficient of friction" - "which will fix and reduce the load coefficient of friction" for consistency and grammatical correctness. 2. "loading coefficient of friction" - should be "load coefficient of friction" since the phrase is mentioned consistently throughout the text. 3. "the jaw crusher machine" - consider changing to "jaw crusher machines" for consistency in plurality. 4. "counter weight" - should be "counterweight" (spelling correction). 5. "and then it will store energy" - should be "and stores energy" for better flow. 6. "handling lubrication" - it should be "hand lubrication" for accuracy. 7. "outside dust, water, foreign matter and harmful materials enter into the bearing part" - should be "outside dust, water, foreign matter, and harmful materials from entering the bearing part" for grammatical structure. 8. "that set several lined ring seal teeth" - should be "that sets several lined ring seal teeth" for subject-verb agreement. 9. "and teeth" - it should be "and between the teeth" for clarity. 10. "la" - the phrase "and the cavity expansion between teeth and teeth" is awkward and should be rephrased for clarity; it would read better with “and the cavity expanding between the teeth.” 11. "in the process of getting through the winding maze" - could be simplified to "when passing through the winding maze" for clarity and conciseness. --- 【第 3 段建议】: 1. "Demand(multiple):" 应为 "Demand (multiple):" 2. "Materials (brochures, catalogs）" 应为 "Materials (brochures, catalogs)"（使用标准的右括号） 3. "EPCO Service" 应为 "EPC Service" 4. "Copyright © 2026" 应为 "Copyright © 2023"（年份错误，根据上下文应为2023年）
