摘　　要：针对现有磁选设备分选高岭土除铁效果不好、处理量小、容易堵塞的现状,开发了ZQS-X-1000新型磁选机,该机具有磁场强度高、磁场分布均匀,采用独特的组合磁介质,配合高压水、高压气进行卸矿的特性.工业试验结果表明,该机具有处理量大、生产效率高、生产指标良好及长期运行平稳的特点.应用该机处理福建某含Fe 2O 3为0.55%和烧成白度75.2的高岭土原料,在给矿时添加六偏磷酸钠0.4%、矿浆浓度17.5%、给矿量25 m^(3)/h的条件下,经一次磁选可以取得产率84.15%、含Fe 2O 3品位0.29%及烧成白度88.7的优质高岭土产品.There were some disadvantages found in the magnetic separator on processing kaolin,such as in efficiency of removing ferrous,lower capacity,easy to be plugged.In this paper,a novel type magnetic separator with high strength and uniformly distributed magnetic field,unique combined magnetic medium,high pressure water and gas for washing,named ZQS-X-1000 was developed.Industrial experiments showed that the novel separator has a good performance of large capacity,high production efficiency,high quality of products,long-term operational stability.Kaolin raw ore with 0.55%Fe 2O 3 and 75.2%calcination whiteness in Fujian province was magnetic separated by the novel equipment.Under the pulp conditions of 17.5%pulp density,0.4%sodium hexameter phosphate concentration and 25 m 3/h pulp feed capacities,high quality kaolin products with 0.29%Fe 2O 3 and 88.7%calcination whiteness was obtained through only one time separation.
