【第 1 段建议】: 1. "lmpact"应为"Impact"。 --- 【第 2 段建议】: 1. "a large number of urban garbage" should be "a large number of urban garbages" or "a large amount of urban garbage" for correctness depending on intended meaning. 2. "the material can be broken in the first line" - "the material can be broken in the first stage" might be clearer, although not incorrect. 3. "the rational and compact space layout of the unit" - "The rational and compact space layout of the unit" should be capitalized as it begins a new sentence. 4. "and also according to customer requirements for product material type, process, process configuration" - "process" is repeated and should be rephrased for clarity. 5. In point 4 and 5, there should be a period at the end of each point. 6. "combined operation can be combined for coarse crushing" - the phrase "can be combined" is redundant. 7. "the integration of the portable crushing station, can be used alone, can also according to customer requirements" should include a new sentence or rewrite for better flow. 8. Consistency issue with "the integration of the portable crushing station" vs "the crushing station" in point 6 - should maintain consistent terminology. Overall, consider adding transitions for better flow and coherence. --- 【第 3 段建议】: 1. "Demand(multiple):" 应为 "Demand (multiple):"（在 "Demand" 和括号之间需要加空格） 2.
