【第 1 段建议】: 1. "lmpact" should be "Impact" (there's a lowercase 'l' instead of 'I'). 2. "SMP Crushing Plant" should be corrected if it should be in a different format (inconsistent casing). 3. "High Weir Spiral Classifier" should have a single space, not two, before "Spiral". 4. "Submerged Spiral Classifier" should have a single space, not two, before "Spiral". 5. "Wheeled Bulk Reception Feeder" could be rephrased for clarity to indicate it is different from "Tracked Bulk Reception Feeder". Note: Items with "Grinding Mil" at the end are cut off and should read "Grinding Mills". Additionally, some terms may not be consistently formatted (e.g., "Crusher" appears in full caps in some places but not others), which should be standardized based on the desired style. --- 【第 2 段建议】: 1. "Summary："中的冒号应为英文半角冒号，即"Summary: "。 2. "and chalk. Calcium carbonate is also the main component of shells of marine organisms, snails, pearls, and eggshells." 中的“eggshells”应为单数形式“eggshell”以与“component”保持一致。 3. "soluble calcium salts." 后面应增加一个句号以结束该句。 4. "Calcium carbonate manufacturing process" 中的句子没有标点符号，应为“Calcium carbonate manufacturing process: ”。 5. "processing plant" 中的“plant”应为复数形式，即“plants”以符合同一上下文中的复数用法。 6. "general overview of the typical processes involved in a calcium carbonate processing plant：" 应将最后的冒号更改为句号，以结束该句。 7. 在“Quarrying or Mining:”中，“Mining”后面的冒号应为句号。 8. "involved in a calcium carbonate processing plant:" 中的句子没有完整结束，建议以句号结束。 请做相应的修改。 --- 【第 3 段建议】: 1. "Vertical roller mill utilize" should be "Vertical roller mills utilize" (pluralization issue). 2. "Vertical mil" at the end should be "Vertical mill" (spelling error). --- 【第 4 段建议】: 1. "ls are known" - 应为 "mills are known"。 2. "calcium carbonate ball mill" - 首字母应大写为 "Calcium Carbonate Ball Mill"。 3. "the ball mill" - 应为 "a ball mill" 以保持一致性。 4. "calcium carbonate particles, typically in the form of limestone or marble," - 句子结构可改为 "calcium carbonate particles, which are typically in the form of limestone or marble," 以提高可读性。 5. "are usually in the range of several micrometers to a few millimeters in diameter" - 为了清晰，应为 "are usually in the range of several micrometers to a few millimeters in diameter."（句末加上句号） 6. "Milling Process:" - 使用 "Milling Process:" 时，后面句子应该是大写，即 "The ball mill rotates horizontally..."。 7. "Classification equipment, such as air classifiers or sieves" - 在此语境中，"such as"后一词应以 "are" 引入，例如 "Classification equipment, such as air classifiers or sieves, are used to ensure..."。 8. "fur" - 似乎是个错别字，应为"further"。 调整上述问题文本可以改善文档的可读性和专业度。 --- 【第 5 段建议】: 1. "the intended application" - "the" should be removed for clarity. 2. "the ratio of calcium carbonate to grinding media can affect the grinding efficiency and the final particle size distribution." - Suggest adding a comma after "distribution". 3. "Raymond mill is a type of grinding mill that is specifically used for grinding calcium carbonate..." - "Raymond mill" should be "Raymond Mills" for consistency. 4. "Raymond mills have a vertical structure with a small footprint and a strong system of pulverizing, drying, grinding, and powder selection." - "system" should be "systems" for subject-verb agreement. 5. "The material is fed into the grinding chamber between the grinding roller and the grinding ring, and the grinding roller applies pressure to the material, resulting in grinding and pulverizing of the calcium carbonate particles." - "resulting in grinding and pulverizing of the calcium carbonate particles" could be simplified to "resulting in the grinding and pulverizing of calcium carbonate particles". 6. "They are commonly used in the production of calcium carbonate powders with a fineness ranging from 80 mesh to 600 mesh." - "Calcium carbonate powders" should be "calcium carbonate powder" for consistency. 7. "Here are some common applications of calcium carbonate powder:" - "applications" might be better phrased as "application areas" for clarity. 8. "Calcium carbonate is widely used in the construction industry for its ability to enhance the properties of building materials." - Consider changing to "enhancing the properties". 9. "It is used as a filler in concrete, mortar, and stucco to improve strength, durability, and workability." - Consider removing "and" before "workability" for parallel structure. 10. "Calcium carbonate can also be used as a coating material for walls and ceilings." - Consider removing "also" for concise phrasing. 11. "It improves the paper's brightness, opacity, and smoothness while reducing costs and enhancing printing properties." - "properties" should be considered singular for better impact: "property". 12. "Calcium carbonate is added to plastics and rubber products as a filler and reinforcement agent." - "reinforcement" should be pluralized to "reinforcing agents". 13. "It provides opacity, whiteness, and coverage while improving the paint's rheological properties and reducing costs." - Suggest adding a comma after "coverage". 14. "Calcium carbonate is used as a dietary s" - Sentence is incomplete and should be revised to include a complete thought. Overall these issues need addressing for clarity and grammatical correctness. --- 【第 6 段建议】: 1. "upplement" 应为 "Supplement" 2. "WhatsApp" 应为 "WhatsApp" 3. "Materials (brochures, catalogs）" 中的英文括号应使用标准形状，应该是 "Materials (brochures, catalogs)"，且 "catalogs" 应为 "catalogues" (美式拼写不一致)
