攀钢密地选钛厂强磁选生产系统整合升级改造的探讨

Discussion on the Integration and Upgrading of High Intensity Magnetic Separation Production System of MIDI Titanium Concentrator of Panzhihua Steel

目前选钛厂的强磁工序主要采用的是Φ2000 mm以下的高梯度强磁机,最大台时能力仅为80 t/h,其产能较低,设备投入数量较多,配套公共辅助设施多,总体能耗高;且已运行12 a以上,目前故障频繁,需要进行设备更新。而目前国内的高梯度强磁机最大型号已达Φ4000 mm,台时能力可达550 t/h,生产实践证明其性能优良。本文主要探讨了选钛厂强磁选生产系统的优化升级改造方案:拟采用大型化的高性能设备取代现有故障频繁的小型设备,并对全厂的强磁选工序流程进行优化整合升级改造,从而达到节能降耗、减员增效、提高生产效率和降低生产成本的效果。

Now the high gradient magnetic machines with the diameter below Φ2000 mm are mainly used in the high-intensity magnetic process of the titanium Concentrator,with maximum 80 t/h.They have low production capacity,more equipment investment,more supporting public and auxiliary facilities,as well as high overall energy consumption.Moreover They have been running for more than 12 years and have frequent faults.So they needs to update the equipment.At present the largest model of high gradient magnetic machine in China has reached Φ4000 mm,and the per hour capacity can reach 550 t/h.The production practice has proved that its performance is excellent.Therefore,this paper mainly discusses the optimization and upgrading scheme of high-intensity magnetic production system in titanium Concentrator:large-scale high-performance equipment is proposed to replace the existing small-sized equipment with frequent faults,and the high-intensity magnetic process flow of the whole plant is optimized,integrated and upgraded,so as to achieve the effect of energy saving and consumption reduction,staff reduction and efficiency improvement,production efficiency improvement and production cost reduction.
