【第 1 段建议】: 1. "lmpact" should be "Impact" (capitalization issue). 2. "Spiral Classifier" should have consistent capitalization; "High Weir Spiral Classifier" and "Submerged Spiral Classifier" (extra spacing before "Spiral"). 3. "Aggregates Belt Conveyor" - consider "Aggregates belt conveyor" (inconsistent capitalization with the rest of the list). 4. "EPCO" - it may require consistent formatting or clarification if it's an acronym. 5. "business" should be capitalized in the "HOME" navigation to match the other capitalized sections. 6. Remove the extra space in "High Weir Spiral Classifier" and "Submerged Spiral Classifier". Overall, some of the issues are related to spacing and inconsistent capitalization. --- 【第 2 段建议】: 1. Summary：应该改为 Summary:（将中文冒号替换为英文冒号） 2. crushing, screening, and classification processes 应为 crushing, screening, and classification processes（去掉多余的逗号） 3. jaw crusher, impact crusher or sand making machine 应为 jaw crusher, impact crusher, or sand making machine（在“impact crusher”和“or”之间添加逗号） --- 【第 3 段建议】: 1.

"Manufacturing of sand used in specialty construction applications, such as precast c" - Incomplete sentence ending, possibly missing text. 总结：存在小的表达不清和不完整的地方。 --- 【第 4 段建议】: 1.
