【第 1 段建议】: 1. "lmpact" should be corrected to "Impact" (the letter 'l' is in lowercase). 2. "and Screen" should be "and Screening" for consistency with other names (Mobile Crushing & Screening). --- 【第 2 段建议】: 1. "ball mill" should be consistently capitalized as "Ball Mill" for proper noun usage. 2. "the same ore and cannot" should have a comma before "and" for better clarity: "the same ore, and cannot". 3. "and the proportion of lump and powder ore should be reasonable and stable" should have "the" before "proportion": "the proportion of lump and powder ore". 4. "at the feeding port of the ball mill belt" should be "at the feeding port of the Ball Mill belt" for consistency with capitalization. 5. "causing unstable production" in the last sentence of point 1 could be more clearly stated with a comma before "and": "of Ball Mill, and cause unstable production". 6. "water-feeding volume of ball mill" should be "water-feeding volume of the Ball Mill" for consistency with capitalization. 7. "becomes larger, and the grinding fineness becomes finer." should be revised for punctuation to improve flow: "becomes larger, and the grinding fineness becomes finer." 8. "Ball mill speed, classifier speed, classifier impeller spacing" should have consistent capitalization: "Ball Mill speed, classifier speed, classifier impeller spacing". 9. "the distance between the classifier impeller have been determined" should be "the distance between the classifier impellers has been determined" to correct subject-verb agreement. 10. "the volume of flushing water at the di" appears to be an incomplete sentence and should be completed or removed. --- 【第 3 段建议】: 1. "scharge" should be "discharge" (missing "d"). 2. "thinner" is repeated unnecessarily. 3. "in time during the operation process of ball mill" should be "in time during the operation process of the ball mill" (missing "the"). 4. "the classifier when the equipment was installed," should have a comma after "installed" (incorrect comma usage). 5. "the lower opening of the classifier is low" has redundancy; it can be simplified. 6. "the amount of returned sand increases, and the grinding fineness is relatively fine" is repeated; should clarify or vary the phrasing. 7. "due to carelessness, the main shaft is not put down completely" is awkward; could be reworded for clarity. 8. "not bee" should be "not been" (incorrect verb form). --- 【第 4 段建议】: 1. "has not add" should be "has not added" 2. """ should be replaced with quotation marks (") 3. "the finer the crushing particle size, the better, and "more crushing and less grinding"" should be "the finer the crushing particle size, the better, and 'more crushing and less grinding'" 4. "Get Solution & Quotation" should be "Get Solution & Quotation" (remove the space before "&") 5. "Please fill out the form below, and we can satisfy any of your needs including equipment selection, scheme design, technical support, and after-sales service." should be rephrased for clarity (optional). 6. "WhatsApp" appears twice as separate entries, which may not be necessary. 7. "Phone" without a label may cause confusion. 8. "WeChat No." is incomplete without a follow-up text. Additional considerations might be made regarding the overall formatting and presentation but were not specifically requested in the instructions. --- 【第 5 段建议】: 1. "Materials (brochures, catalogs）" - 使用的括号类型不一致，应该使用英文括号： "Materials (brochures, catalogs)"。 2. "WhatsApp:+86 13761974616" - "WhatsApp:"后应有一个空格。 3.
