【第 1 段建议】: 1. "lmpact" should be "Impact" (incorrect character 'l'). 2. "Spiral Classifier" is inconsistent. It should match the capitalization in other instances ("Spiral Classifier" instead of "spiral classifier"). 3. "EPCO" may need clarification on whether it is an acronym, but it appears correct as is. 4. "What is the sand making machine for quartz sand" should end with a question mark. --- 【第 2 段建议】: 1. "t is the sand making machine" - Should be "It is the sand making machine". 2. "the automatic operation" - Should be "automatic operation" (remove "the"). 3. "the sand making machine has the low failure rate" - Should be "The sand making machine has a low failure rate" (capitalization and "a" instead of "the"). 4. "and less investment, which conforms to the modern trend of energy saving, low carbon, and green environmental protection" - Consider changing "investment" to "investments" for consistency in plurality. 5. "Get Price More" - This phrase needs revision for clarity. It might be better as "Get more pricing information" or "Request a price quote". --- 【第 3 段建议】: 1. "Materials (brochures, catalogs）"：括号的右侧使用的是中文标点，应该使用英文标点。 2. "Service Support"和"About SBM"后面的项目未统一使用冒号或不使用，建议添加冒号以保持一致。 3. "Sales Hotline: 0086-21-58386189 0086-21-58386176"：两个电话号码之间缺少标点，建议使用分号或换行。 4. "Copyright © 2026"：年份应为2023而不是2026。 5. "Copyright © 2026 Shanghai Shibang Machinery Sales Co., Ltd. Website Map|Legal Notice|Contact Us"：建议在“Website Map”和“Legal Notice”之间添加空格以提高可读性。 6. "function(w,d,s,l,i){"和后续内容中的分号以及一些括号未对齐，可能影响代码的可读性。 这些是我发现的问题。
