【第 1 段建议】: 1. "lmpact" should be corrected to "Impact" (the letter 'l' is incorrect). 2. "SMP Crushing Plant" may not be a standard term; please verify the term used. 3. "Belt Conveyor" should not have a capitalized 'B' if it is being used as a general description (common usage). 4. "EPCO" may need verification as it is typically “EPC” or “EPC/O” (confirm whether this is a standard acronym). 5. Consistency in bullet points for the lists provided; they should either all have a period at the end or none. These issues do not affect the readability significantly but maintaining consistency and accuracy is vital. --- 【第 2 段建议】: 1. "charac" should be "characteristic" 2. The second "What are the common crushing methods for crushers:" should be removed as it is redundant. 3. The sentence "Then the crushing method of the crusher equipment is divided into two types: mechanical crushing and non-mechanical crushing." should be rephrased to avoid repetition of "crushing method" and "crusher." 4. "This method is characterized by the fact that it is subjected to bending force in addition to the external force, and thus is easy to make The ore is broken." contains incorrect capitalization; "The" should be lowercase. 5. "hydroelectric effect is broken" should be "hydroelectric effect breaking." 6. The punctuation, such as commas and semicolons, should be reviewed for consistency and clarity throughout the text. 7. "high-frequency or over-frequency electromagnetic waves" may be stated more concisely as "high-frequency electromagnetic waves" if "over-frequency" is unnecessary. Please also ensure all instances of "crushing" consistently use either singular or plural as fits the context, but that wasn't explicitly highlighted in the given text.
