摘　　要：分析了锌加压浸出工艺对矿料产品粒度及浓度的特殊要求,对传统球磨磨矿工艺和引进的立式砂磨磨矿工艺进行了分析并指出了不足,开发了先进的锌氧压浸出型专用立式螺旋搅拌磨技术,并介绍了在西部矿业10万t锌氧压浸出冶炼厂的应用及优势。在给矿粒度-75μm占50%、磨矿浓度65%~68%的条件下,最终产品细度可以稳定在-45μm占96%~98%。与某厂进口立式砂磨机进行经济技术指标对比,投资和运行费用仅为立式砂磨机的1/3。Special requirements on particle size and concentration of mineral products in zinc pressure leaching were analyzed.Traditional ball milling and newly introduced vertical sand milling were analyzed and their deficiencies were pointed out.The advanced and appropriative vertical screw agitating mill technology was developed for zinc oxidizing pressure leaching.Applications and technical advantages of vertical agitating mill in zinc oxygen pressure leaching in Western Mining Corporation with capacity of 100kt/a were introduced.Particle size of final product of-45μm is 96% ~98% under the conditions including feed particle size of-75μm of 50%,grinding concentration of 65%~68%.Both investment and operation cost is only 1/3of imported vertical sand mill based on comparison of technical and economic indexes.
