【第 1 段建议】: 1. "Vertical Shaft lmpact Crusher" - 'l' should be 'I' (capital 'I'). 2. "Case" - should be pluralized to "Cases" to match the header style. 3. "EPCO" - check if this is a typo or an acronym, as it may need further context or correct capitalization if it's an acronym. 4. "Bulk Material Handling - Aggregates Belt Conveyor" - "Aggregates" should likely be lowercase for consistency with other headings unless it is a specific product name. 5. "Mobile Demand" - check for consistency with whether other headings are singular or plural. 6. The spacing around the line breaks is inconsistent; some lines are spaced more than others. 7. "To Catch a Glimpse of the 5t" - '5t' should be '5th' for correct ordinal representation. Note: While "Aggregates" in "Aggregates Belt Conveyor" and similar phrases may be correct if it is part of a specific product name, their usage should be checked for consistency throughout the document. --- 【第 2 段建议】: 1. "the aggregates industry is being in a fast growing stage" → "the aggregates industry is in a fast-growing stage" 2. "the enterprises, the investors, the practitioners and the governmental institutes" → "enterprises, investors, practitioners, and governmental institutions" (remove "the" before plural nouns and change "institutes" to "institutions" for better usage) --- 【第 3 段建议】: 1. "concerted," - 应该使用句号而不是逗号。 2. "SBM, as a leading brand in mining machinery industry," - 应为 "in the mining machinery industry"。 3. "with more than 8000 customer companies" - 数字应写成 "8,000"。 4.
