许多铁精矿球团试验和球团厂工作实践都证明,精矿水分对球团指标的影响极大。对于任何细磨物料的混合物都有一个最佳的水分值(用吸附水或结合水和毛细水量求得),以保证达到所要求的球团指标和制得的球团矿具有足够的机械性能。同时,现有脱水设备在磨矿细度提高到-0.05mm粒级占92％或更高时,不能保证精矿水分达到最佳球团水分。 Many iron ore pellets test and pellet plant work have proved that the concentrate moisture has a great impact on the pellet index. For any mixture of finely ground material, there is an optimum moisture value (obtained with adsorbed water or combined water and capillary water) to ensure that the desired pellet index is achieved and that the resulting pellets have sufficient mechanical performance. At the same time, the existing dehydration equipment can not guarantee the optimal moisture content of the concentrate when the grinding fineness is increased to -0.05mm, accounting for 92% or more.
