【第 1 段建议】: 1. "lmpact"应更正为"Impact"（字母错误）。 2. "High Weir Spiral Classifier" 和 "Submerged Spiral Classifier" 中的空格错误，需确保"High Weir Spiral Classifier"和"Submerged Spiral Classifier"仅有一个空格。 3. "SMP Crushing Plant" 中的“SMP”应与“Crushing Plant”之间没有空格。 请注意，以上是文本中发现的问题，可能需要进一步上下文来确认同义词或语法的使用是否正确。 --- 【第 2 段建议】: 1. "operators" should be capitalized at the beginning of the sentence: "operators should adjust the gap properly according to requirement..." 2. "found out" should be "find out": "operators should found out the loosen screw bolts and tighten them." 3. "lubrication oil/grease" should be consistent in format: "lubrication oil and grease" 4. "the sound of reducer" should be capitalized at the beginning of the sentence: "the sound of reducer in the work process of ball mill should be stable and uniform." 5. "the lubrication oil or grease goes bad" could be rephrased for clarity: "the lubrication oil or grease may be degraded." 6. "to deal with it immediately" could be more precise: "to address the issue immediately." Corrected version of some sentences could look like this: - "Operators should find out the loosened screw bolts and tighten them." - "The lubrication oil and grease may be degraded." - "The sound of the reducer in the work process of the ball mill should be stable and uniform." Additionally, the title "ent Problems And Solutions" appears to be incomplete and needs context for clarity. Overall, these corrections clarify meaning and align with standard English grammar and punctuation. --- 【第 3 段建议】: 1. "Stone Crusher In Ethiopia" - "In" should be lowercase: "Stone Crusher in Ethiopia" 2. "Mobile Crusher For Sale South Africa" - "For" should be lowercase: "Mobile Crusher for Sale South Africa" 3. "WhatsApp:+86 13761974616" - There should be a space after "WhatsApp:": "WhatsApp: +86 13761974616" 4. "Sales Hotline: 0086-21-58386189 0086-21-58386176" - There should be a semicolon or new line separating the two numbers: "Sales Hotline: 0086-21-58386189; 0086-21-58386176" or "Sales Hotline: 0086-21-58386189\n0086-21-58386176" (Note: The line "d=document.domain;c=location.search;tags = document.getElementsByTagName("a");for(var i=0;i-1){tags[i].href=tags[i].href+c;}}" appears to be an incomplete code and is not relevant to the text proofreading.)
