【第 1 段建议】: 1. "lmpact"应为"Impact" (字母错误，'l' 应该是 'I')。 2. "Spiral"中的空格丢失，应该是 "High Weir Spiral Classifier" 和 "Submerged Spiral Classifier"。 3. "Aggregates"重复出现（在"Cases"和"Business"部分），可考虑合并。 4. "Localized Service" 中的 "Localized" 可能是使用了美式拼写，需与其他项 (如 "Français") 统一使用英式或美式拼写。 5. 在“Home > Blog > What are the requirements for Raymond mill's”部分，缺少结束标点符号。 具体修改建议可以更详细，以确保符合统一标准。 --- 【第 2 段建议】: 1. "a grin" should be "a grinder." 2. "Raymond Mill" should be uniformly capitalized as "Raymond mill" throughout the text for consistency. 3. "Rayleigh's" should be "Raymond's" in "Rayleigh's own factors." 4. "the lower the output" should be "the lower the output is." 5. " " appears twice and should be removed to ensure proper formatting. 6. "the composition of the material" should start with a capital "The." 7. "it is best here" is awkwardly phrased; consider revising for clarity. 8. "to Choos" should be "to Choose" at the end of the text. --- 【第 3 段建议】: 1. "WhatsApp" should be capitalized: "WhatsApp" 2. The plural form "brochures, catalogs)" should have a closing parenthesis: "brochures, catalogs)" 3.
