【第 1 段建议】: 1. "lmpact"应为"Impact"（大写字母I）。 2. "Spiral Classifier"中的"High Weir"与"Submerged"需要调整为“大写首字母”（即“High Weir Spiral Classifier”和“Submerged Spiral Classifier”）。 3. "EPCO"在此上下文中可能是一个拼写错误，建议确认是否是"EPC"或"EPCC"。 4. "Localized Service"应为"Localized Services"（复数形式）。 5. "Radial Telescopic Stacker" 和 "Ship Loader"之间缺少逗号。 以上为检查出的错误。 --- 【第 2 段建议】: 1. "Summary：" -> "Summary:" 2. "Raymond Mill" should be consistent in capitalization throughout the text. Use either "Raymond Mill" or "raymond mill" consistently. 3. "anti-corrosion treatment" should be consistently hyphenated or not. 4. In "parts can ensure that the Raymond mill works normally, that is, in the low-cost maintenance state," the comma before "that is" should be replaced with a semicolon or a period for better clarity. 5. "the necessary maintenance work for Raymond Mill can keep it in good working condition and extend the service life." can be clarified by rephrasing to "the necessary maintenance work for the Raymond Mill can keep it in good working condition and extend its service life." 6. "Get Solution & Quotation" should have consistent capitalization; it could also be rephrased for clarity. 7. "Demand(multiple):" -> "Demand (multiple):" (space needed before parenthesis) 8. "Materials (brochures, catalogs）" -> "Materials (brochures, catalogs)" (mismatched parenthesis).
