【第 2 段建议】: 1. "one jaw crusher and three sets of single cylinder hydraulic cone crusher" 应为 "one jaw crusher and three sets of single-cylinder hydraulic cone crushers" (需添加连字符并将“cone crusher”变为复数形式) 2. "is because it is recommended" 可考虑改为 "is due to it being recommended" (表达更自然) 3. "the quality satisfying" 应为 "the quality is satisfying" (需添加“is”) 4. "achieved not only capacity expectations, but also good profit" 可考虑改为 "achieved not only capacity expectations but also good profits" (需将“profit”改为复数形式，并删除逗号以符合并列结构) 5. “Turkey Copper Ore Crushing Plant” 中"Turkey"应为"Turkish" (应该用形容词形式)
