摘要: 浮选机矿化器是用于浮选矿浆预处理的重要设备,其性能的优劣直接影响到浮选机的工作效果。文章通过流体力学仿真软件FLUENT对XJM-KS型浮选机矿化器的内部流场进行数值仿真,重点研究了聚焦式喷嘴布置所带来的流场特征。模拟结果表明,高速的矿浆射流能够在混合室内产生-2.43×10Pa的负压区,从而吸入大量的空气,实现空气与矿浆的有效混合与预矿化,与传统的机械搅拌式矿浆预处理装置相比,该矿化器能够大幅度提高预矿化效果。

Abstract: Abstract: Pre-mineralizing device is a crucial apparatus that utilized in flotation pulp pre-mineralization of which performance tremendously effect the result of flotation process. In this essay, the CFD simulation software is induced in analyzing the features of internal flow field of pre-mineralizing device and the differences between two injectors with different feeding method. In addition, the features of dynamic flow field of focused injector is interpreted. The outcome indicates that the performance of pre-mineralization device matches the demand of industrial application.
