【第 2 段建议】: 1. "ZSW490*130" should be "ZSW490 × 130" (for clarity in dimension notation) 2. "HPT300 multi-cylinder hydraulic cone crusher (12 sets)" - "12 sets" appears excessive; clarification needed on whether it should be singular/plural based on context. 3. "3Y2460 circular vibrating screen (2 sets), 2Y2460 (1 set)" - need clarification on whether "2Y2460" should specify what it is for consistency with others. 4. "VSI5X114593 sand-making machine (3 sets)" should be "VSI5X-114593 sand-making machine (3 sets)" to clearly indicate model designation. 5. "PEW1100 European hydraulic jaw crusher" should be "PEW1100 European Hydraulic Jaw Crusher" to maintain capitalization consistency with other equipment names. 6. "Multi-cylinder hydraulic cone crusher" should be "Multi-Cylinder Hydraulic Cone Crusher" for consistency with capitalization. Overall, the formatting and consistency of equipment naming conventions need attention to ensure clarity. --- 【第 3 段建议】: 1. "an Jaw Crusher" 应为 "a Jaw Crusher" 2.

Combining faster rotation speed with stroke improves greatly rated power and capacity of HPT crusher" 中的 "greatly rated power" 应为 "greatly improves the rated power"（语法错误） 5. "the design of the special crushing cavity and the rotating speed, proportion of fine cubic material gets improved." 应为 "the design of the special crushing cavity and the rotating speed, the proportion of fine cubic material is improved."（语法错误） 6. "third-stage cone crushing" 应为 "third-stage cone crusher"（应使用名词形式） 7. "customer site" 中的 "site" 应为 "Sites"（需确保复数形式） 8. "Tuff Crushing PlantTuff is fed by vibrating feede" 中的 "PlantTuff" 应为 "Plant.
