摘　　要：某5 000t/d水泥生产线石灰石破碎系统原采用重型板式喂料机+双转子锤式破碎机系统,存在台时产量低、出破碎机物料粒度大等问题。通过采取在重型板式喂料机与破碎机间增加五辊式筛分机,将原破碎机更换为新型双转子锤式破碎机,对重型板式喂料机进行抬高、截断及移位等技改措施,石灰石破碎机篦板篦缝减小,台时产量提升至1 200t/h,出破碎机物料粒度显著降低,且设备稳定性增强,备件使用寿命延长。改造后,立磨台式产量由390t/h提高至410t/h,粉磨电耗降低了1.30k W·h/t,每年可节约电费、人工费、备件费约119.2万元,预计3年左右收回投资成本,改造效果较好。通过采取精细规划改造位置、深化设备厂家与施工单位协同合作、持续优化设备性能、加强员工培训与技术支持等措施,可进一步巩固和提升技术改造效果。The original limestone crushing system of a 5 000t/d cement production line employed a heavy-duty plate feeder and a double-rotor hammer crusher.However,it suffered from low hourly output and large particle size of crushed materials.To address these issues,technical modifications included installing a five-roller screening machine between the heavy-duty plate feeder and the crusher,replacing the original crusher with a new double-rotor hammer crusher,and adjusting the feeder through elevation,truncation,and repositioning.These improvements reduced the crusher grate gaps,increased the hourly output to 1 200t/h,significantly decreased the particle size of crushed materials,enhanced equipment stability,and extended the service life of spare parts.Post-reform,the vertical mill's hourly output rose from 390t/h to 410t/h,grinding power consumption decreased by 1.30kW·h/t,and annual savings in electricity,labor,and spare parts costs reached approximately 1.192million yuan.The investment is expected to be recouped within three years,demonstrating notable success.Further consolidation and enhancement of the technical outcomes can be achieved through meticulous planning of retrofit locations,strengthened collaboration between equipment manufacturers and construction teams,continuous optimization of equipment performance,and enhanced employee training and technical support.
