【第 1 段建议】: 1. "lmpact" should be "Impact" (capitalization error). 2. "other" should be capitalized as "Other" in the context provided. --- 【第 2 段建议】: 1. "liners—"应改为"liners—" (使用正确的长破折号)。 2. "chamber’s"应改为"chamber's" (使用正确的撇号)。 3. "crusher’s"应改为"crusher's" (使用正确的撇号)。 4. "material properties, crusher specifications, production goals, and liner design."应改为"material properties, crusher specifications, production goals, and liner designs." (liner 在此上下文中应为复数形式）。 5. "the nature of the materi"应改为"the nature of the material" (完整单词填写)。 --- 【第 3 段建议】: 1. "Materials are classified by their hardness using scales such as the Mohs hardness scale or through compressive strength testing." - Consider adding a period after "testing" for clearer separation of thoughts. 2. "Abrasiveness" should be "Abrasiveness." 3. "Hard, abrasive materials—such as granite, basalt, quartz, and ore-bearing rocks—exert significant wear on liners." - Use a proper dash (—) instead of "—". 4. "which offers good toughness but lower abrasion resistance." - Consider adding a comma before "but" for better readability. 5. "Moisture and Clays Content" - "Clays" should be singular, "Clay." 6. "Materials with high moisture or clay content tend to stick to the liner surfaces, causing buildup, reduced throughput, and uneven wear." - Consider adding a comma before "and" for proper list separation. 7. "size distribution and shape of the feed material influence liner design." - "size" should be capitalized as "Size." 8. "Crusher Specifications and Operating Parameters" - "Crusher" should be capitalized as "Crusher." 9. "Liner designs are tailored to these models to optimize performance." - Consider altering to "are tailored to optimize performance for these models." 10. "Reduction Ratio Requirements" - "Requirements" should be "Requirement." 11. "The reduction ratio—the ratio of the feed size to the product size—dictates the liner’s profile." - Use proper dashes (—) instead of "—." 12. "revolutio" - This is a cutoff word; it should read "revolutions."
