半自磨机弧形格子板-提升器的设计与应用
|
摘要
对比了半自磨机现有出料端的两种结构,采用离散元计算软件对出料端强制排矿进行仿真模拟,并对弧形结构出料端的实际应用案例进行了数据分析。实践证明,弧形结构在出料端的应用能够提高半自磨机的排矿效率,尤其是顽石可以被及时排出,提高了半自磨机对难磨矿的处理能力。
After comparing two kinds of structure in existing discharge end of the SAG(semi-autogenous)mill, the paper applied discrete element calculation software to simulate the forced discharging operation in the discharge end, and analyzed actual application cases of the curved discharge end. Practice showed the application of the curved discharge end enhanced the discharging efficiency of the SAG mill, especially enhanced the throughput of the SAG mill for refractory mineral due to timely discharge of hard ores.
