"the new types Raymond mill" 应改为 "the new types of Raymond mills"（"types" 后需加 "of" 且"Raymond mill" 应为复数 "Raymond mills"） 4. "ball mill are cheaper than Raymond mill" 应改为 "ball mills are cheaper than Raymond mills"（"ball mill" 和 "Raymond mill" 应为复数） --- 【第 3 段建议】: 1. "the area of ball mill is larger" → "the area of the ball mill is larger" 2. "so the whole control is difficult" → "so the overall control is difficult" 3. "In conclude" → "In conclusion" 4.

"WhatsApp:+86 13761974616" 应加空格为 "WhatsApp: +86 13761974616" 2. "Sales Hotline: 0086-21-58386189" 与 "0086-21-58386176" 应调整为相同格式，建议为 "Sales Hotline: 0086-21-58386189; 0086-21-58386176" 3. "Website Map|Legal Notice|Contact Us" 应加空格为 "Website Map | Legal Notice | Contact Us" 4. "function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':" 缺少空格的格式较差，建议格式化代码以提高可读性。 5. "for(var i=0;i-1){tags[i].href=tags[i].href+c;}}" 应为 "for(var i=0;i<tag.length;i++){tags[i].href=tags[i].href+c;}" 以使循环条件成立。 建议将代码部分进行格式化以提高可读性。
