【第 1 段建议】: 1. "Vertical Shaft lmpact Crusher" - "lmpact" should be corrected to "Impact" (capital 'I'). 2. "High Weir Spiral Classifier" - There are two spaces between "Weir" and "Spiral"; it should be corrected to one space. 3. "Submerged Spiral Classifier" - There are two spaces between "Submerged" and "Spiral"; it should be corrected to one space. 4. "EPCO" should be "EPC" (if referring to "Engineering, Procurement and Construction"). 5. "Pipe Jacking Machine" - should be followed by a period if it is a complete thought or header. (Note: If "EPCO" was specifically used in a different context, further clarification may be needed.) --- 【第 2 段建议】: 1. "ers of a Large-diameter Impact Crusher" - 应为 "Features of a Large-diameter Impact Crusher" 2. "Summary：" - 应为 "Summary:" (去掉空格前的空白) 3. "chapter into smaller particles." - 应为 "chapter into smaller particles." (在 "chapter" 前需加 "to") 4. "high-speed impact of the hammer and is then" - "is then" 应为 "and then" 5. "the purpose of changing the particle size and shape of the material." - "the shape of the material." 应为 "the shape of materials." (保持一致性，复数形式) 无错误 --- 【第 3 段建议】: 1. “(recommend≤300)” 应更正为 “(recommend ≤ 300)” 2. “(recommend≤600)” 应更正为 “(recommend ≤ 600)” 3. “(recommend≤700)” 应更正为 “(recommend ≤ 700)” 4. “(recommend≤800)” 应更正为 “(recommend ≤ 800)” --- 【第 4 段建议】: 1.

"Copyright © 2026 Shanghai Shibang Machinery Sales Co., Ltd." 应改为 "Copyright © 2023 Shanghai Shibang Machinery Sales Co., Ltd."（年份错误） 5. "Get Solution Online Chat" 中的 "Get Solution" 应改为 "Get Solutions"（复数形式） 6. “function(w,d,s,l,i){...” 中的 JavaScript 代码存在悬尖括号但这不是拼写错误，而是代码格式问题。 其他内容没有错误。
