【第 1 段建议】: 1. "lmpact" should be "Impact" (the letter "l" is incorrect). 2. "desulfurizati" should be "desulfurization" (the word is incomplete). --- 【第 2 段建议】: 1. "on in power plant" 应为 "On in power plant"（句首字母需大写）。 2. "which are rich" 应为 "which is rich"（材料名词为单数，需用is）。 3. "Here we’re gonna to talk" 应为 "Here we’re gonna talk"（去掉多余的to）。 4. "desulfuration" 应为 "desulfurization"（拼写错误）。 5. "the output size of grinding mill need to reach" 应为 "the output size of the grinding mill needs to reach"（需改为"needs"以符合主谓一致）。 6. "For the coal boiler which is low sulfur content in combustion" 应为 "For the coal boiler which has low sulfur content in combustion"（需要加has以形成完整句子）。 7. "When burning coal is with high sulfur content" 应为 "When burning coal has high sulfur content"（同样需要加has）。 8. "there has relevant reference foe choosing grinding mill" 应为 "there are relevant references for choosing a grinding mill"（"has"改为"are"，"foe"改为"for"，并添加"a"）。 9. "2 limestone grinding mill" 应为 "2 limestone grinding mills"（复数形式）。 10. "which can prevent "running powder"" 应为 "which can prevent 'running powder'"（中文引号应改为英文引号）。 11. "and the quality of the finished product can be controlled effectively" 此句应与前一道连接成一个整体，建议改为："...requirements of powder fineness, and the quality of the finished product can be effectively controlled."（“可以”需要词序调整以提高流畅性）。 --- 【第 3 段建议】: 1. "applicate" should be "applied". 2. "solution" should be "solutions" to match the plural form. 3. "you message" should be "your message". 4. "the form, there" should be "the form; there" for proper punctuation. 5. "WhatsApp" is repeated without context (should it be included once?). 6. "Demand(multiple):" should have a space after the word 'Demand' and before '(multiple):'. 7. "Materials (brochures, catalogs）" should have a closing parenthesis that is consistent in style; (should replace ） with ). 8. "To be Our Age" appears to be incomplete or unclear; consider revising for clarity.
