【第 1 段建议】: 发现的问题： 1. "lmpact" 应为 "Impact"（字母 'l' 错误） 2. "Spiral Classifier" 中的 "Spiral" 前面的空格不需要，保持统一格式。 3. "Radial Telescopic Stacker" 和 "Ship Loader" 应为 "Radial Telescopic Stackers" 和 "Ship Loaders" （复数形式不一致）。 其它部分无错误。 --- 【第 2 段建议】: 1. "30 tons" should be consistently written as "30-ton" when used as an adjective (e.g., "30-ton vertical mill"). 2. "R&D" should be written as "R&D" for proper formatting. 3. "sales and service" should have a comma before "and" for clarity: "sales, and service." 4. "30 tons/hour" should be consistently written as "30-ton/hour." 5. "very large feature is the new concept of "one-stop" service system" - the " should be replaced with " for proper quotation marks: "one-stop" service system. 6. "the company's very large feature" is awkward; consider changing to "a major feature of the company." 7. "we have perfected the after-sales delivery system" - consider removing "the" for clarity: "we have perfected after-sales delivery system." Overall, the text has several punctuation and consistency errors along with some awkward phrasing. --- 【第 3 段建议】: 1. "WhatsApp" should not be repeated. 2. "Demand(multiple):" should have a space before the parentheses: "Demand (multiple):". 3. "Catalogs）" should have a matching opening parenthesis and should be corrected to "catalogs)". 4. Remove the extra space before "Get Solution Online Chat" as it seems inconsistent. 5. In "Contact Us" there should be a consistent way to capitalize or not capitalize. It appears to be inconsistent as there is no capital "U" in "Contact Us" throughout the other mentions. 无错误
