振动斜板盒浓密机在铜街选矿厂尾矿浓缩中的应用

云南华联锌铟股份有限公司铜街选矿厂由于产能的提升，原厂区内自主增设的普通箱式沉降槽已不能满足生产的需要。为确保厂区浓缩系统溢流水的质和量，采用新型高效浓缩设备--振动斜板盒浓密机进行了分流处理改造。调试期间-0.047 mm占53.36%、浓度为11.77%、流量不低于200 m3/h的综合尾矿浆经ZXN-300型振动斜板盒浓密机浓缩处理，所得底流浓度≥35%，溢流水含固量＜100 mg/L，回水率达70%～80%。1 a多的生产实践证明，振动斜板盒浓密机的各项生产指标均优于工艺要求，且设备无故障。与箱式沉降槽相比，振动斜板盒浓密机具有处理能力大、占地面积小、工作效率高、技术性能优越等特点，可广泛应用于微细粒尾矿的高效浓缩。

Application of Vibration Inclined Plate Box Thickener in Tailings Thickening of Tongjie Plant

With the capacity increase of the Tongjie Plant of Yunnan Hualian Zinc Indium Co.Ltd.，the ordinary box settling tank which was independently increased in the original factory was unable to meet the needs of production.In order to ensure the quality and quantity of the overflow water plant thickening system，a new type of highly efficient thickening equipment，a vibration inclined box thickener has been used for the splitting treatment.Through the production practice more than one year，when the -0.047 mm size fraction accounted for 53.36%，the concentration of 11.77%，flow rate of not less than 200 m3/h comprehensive tailings slurry is concentrated by ZXN-300 vibration inclined plate box thickener，the underflow concentration is more than 35%，the overflow solid-containing content less than 100 mg/L，the recovery rate of water is 70%～80%；one year production practice indicated the indexes are better than the original technological requirements，and the equipment is running well without fault；compared with box-settler group，the vibration inclined plate box thickener has the characteristics such as large capacity，little occupied area，high working efficiency and superior performance，it can be widely used in the high efficiency thickening of fine-size tailing.
