【第 1 段建议】: 1. "lmpact"应为"Impact"（大写字母I）。 2. "Spiral Classifier"和"Submerged Spiral Classifier"之间的空格不一致，前者多了一格。 3. "Aggregates"后面多了一个空格。 4. 句末的"Probl"应为"Problem"。 其余部分无错误。 --- 【第 2 段建议】: 1. "we gonna"应为"we're gonna" 2. "feed"应为"fed" 3. “cause”应为“causes” (在“which cause material blockage”中) 4. "Solution:We"应为"Solution: We" （需要在冒号后加空格） 5. "discharging speed"应为"discharge speed" 6. “inside machine”应为“inside the machine” --- 【第 3 段建议】: 1. "damage"应为"damaged"（应为过去分词）。 2. "it's damage"应为"it's damaged"（应为过去分词）。 3. "the machine can't operate normally" 应为"the machine can't operate normally,"（少了句号）。 4. "pay more attention to the maintenance of spindle"应为"pay more attention to the maintenance of the spindle"（缺少定冠词）。 5. "design is improper"应为"design is improper,"（少了句号）。 6. "the crushing effect of impact crusher"从上下文来看应为"the crushing effect of the impact crusher"（缺少定冠词）。 其他方面无错误。 --- 【第 4 段建议】: 1. "the cause of problem" -> "the cause of the problem" 2. "Demand(multiple):" -> "Demand (multiple):" 3. "Materials (brochures, catalogs）" -> "Materials (brochures, catalogs)" (inconsistent use of closing punctuation; should be either both parentheses or none) 4. "WhatsApp:" -> "WhatsApp:" 5. "WhatsApp" repeated; needs clarification on context or removal of redundancy. 6. "Raymond Mill" should be consistent in capitalizing "mill" (either capitalize all terms or none in a list). 7. "SBM Blog" and "Stone Crusher In Ethiopia" should have consistent capitalization (e.g., "Stone Crusher in Ethiopia"). 8. "Product Center" and "Service Support" should be formatted consistently (e.g., either all capitalized or not). 9. "Contact Us" and "Copyright © 2026 Shanghai Shibang Machinery Sales Co., Ltd." should ensure consistency in spacing and punctuation. Overall suggestions: - Ensure terms are consistently capitalized or not. - Remove any repeated items or clarify their necessity.
