【第 1 段建议】: 1. "lmpact" should be corrected to "Impact" (capital 'I' instead of lowercase 'l'). 2. "Spiral Classifier" should be "Spiral Classifier" (the word "Spiral" in "High Weir Spiral Classifier" and "Submerged Spiral Classifier" should not have extra spaces before "Spiral"). 3. "EPCO" should likely be "EPC" depending on the context, but if accurate as "EPCO," then it is fine. 4. There are excessive spaces before and after punctuations, particularly in the "About" and "Blog" sections. 5. Ensure consistency in punctuation with the bullet points; some sections use inline punctuation while others do not. --- 【第 2 段建议】: 1. “Which Grinding Mill Is Suitable For Processing Limestone?” - The question mark should be inside the quotation marks: “Which Grinding Mill Is Suitable For Processing Limestone?” 2. “the main raw material of cement, concrete aggregate, etc. it can also be used as a filler” - “it” should be capitalized: “etc. It can also be used as a filler” 3. “the process of material passing through the mill as finished product for the next step of operation;” - “finished product” should be “finished products” (to match plural context). 4. “when the material discharged from grinding mill after one or several levels of separation” - Add “is” after “material” for clarity: “when the material is discharged from grinding mill after one or several levels of separation” 5. “the fine particles are used as the finished product” - “finished product” should be “finished products” (to match plural context). 6. “over-grinding is easy to occur, and the finely ground materials easily form a cushion layer, which prevents the coarse materials from further grinding, greatly reduces the grinding efficiency and increases the power consumption.” - This sentence is quite long and could benefit from clearer punctuation; consider using a semicolon or breaking into shorter sentences for clarity. 7. “a closed circuit process, which can reduce the phenomenon of over-grinding, improve the efficiency of the grinding mill, and reduce power consumption." - “a closed circuit process” is pluralized in the context earlier; should be “closed circuit processes” for consistency. 8. “while designing a complete limestone grinding plant, there are several steps:” - “while” should be capitalized: “While designing a complete limestone grinding plant, there are several steps:” 9. "consider about the max feed size" - should be “consider the max feed size” (remove “about”). 10. “decides if we should adopt crusher and decides the feed opening o” - should be “adopt a crusher and decides the feed opening of” (add “a” before “crusher” and correct “o” to “of”). --- 【第 3 段建议】: 1. "consider about the capacity" - 应为 "consider the capacity" 2. "the models of grinding mills might also be different" - "models" 应为 "model" 3. "the feed opening of grinding mill" - 应为 "the feed opening of the grinding mill" 4. "the final products discharged from crusher" - 应为 "the final products discharged from the crusher" 5. "the matching of crusher and grinding mill" - 应为 "the matching of the crusher and the grinding mill" 6. "the above mentioned limestone grinding plant" - 应为 "the above-mentioned limestone grinding plant" 7. "which model of grinding mill" - 应为 "which models of grinding mills" 8. "is suitable for the large-scale processing" - 应为 "are suitable for the large-scale processing" 9. "and has the advantages of small area, low investment in civil construction, low noise, and good environmental protection" - "has" 应为 "have" 10. "Raymond mill has stable performance" - 应为 "Raymond mills have stable performance" 11. "low energy consumption and large adjustable range of product particle size" - "adjustable range" 应为 "adjustable ranges" 12. "widely used in many industries" - 应为 "widely used in many industries." 13. "kind of equipment to process" - 应为 "kind of equipment for processing" 14. "used for medium and low hardness of non-flammable and explosive brittle material processing" - 应为 "used for processing medium and low hardness non-flammable and explosive brittle materials" 15. "widely used in the field of industrial grinding" - 应为 "widely used in industrial grinding" 16. "the grading system adopts the mandatory turbo grade structure" - 应为 "the grading system adopts a mandatory turbo grade structure" 17. "the collection system uses pulse collection" - 应为 "the collection system uses pulse dust collection" 18. "care fed evenly and continuously" - 应为 "are fed evenly and continuously" 19. "The ground powder are carried" - 应为 "The ground powder is carried" --- 【第 4 段建议】: 1. "the fineness can reach to 0.008mm" - It should be "the fineness can reach 0.008 mm" (remove "to" and add a space before "mm"). 2. "Please fill out the form below, and we can satisfy any of your needs including equipment selection, scheme design, technical support, and after-sales service." - Remove the extra space before "technical." 3. "Demand(multiple):" - It should be "Demand (multiple):" (add a space between "Demand" and the parenthesis). 4. "Materials (brochures, catalogs）" - Change the closing parenthesis from a right parenthesis to a right square bracket; it should be "Materials (brochures, catalogs)" (use the correct parenthesis). 5. "WhatsApp:+86 13761974616" - It should be "WhatsApp: +86 13761974616" (add a space after "WhatsApp:"). 6. "Sales Hotline: 0086-21-58386189" - It should be "Sales Hotline: +86-21-58386189" (Adding the "+" sign for international dialing). 7. "Copyright © 2026" - If this is referring to the current year, it should be corrected to "Copyright © 2023" (correcting the year to match your initial data).
