摘要

圆锥破碎机在加工采石场岩石以及一些选矿厂的较粗矿石制备过程中发挥着重要作用。巴西伊塔比里特铁矿石制备厂的情况尤其如此，因此优化圆锥破碎机的性能对于实现回路的最大生产率至关重要。这项工作介绍了在巴西（米纳斯里约）一家工业厂房中运行的 HP500 圆锥破碎机的建模结果，这些结果是通过几年来对不同给料和破碎条件的调查得出的。安徒生-惠顿圆锥破碎机模型的一个版本是在综合萃取模拟器中实现的，具有非归一化破碎响应和适合目的的产量模型。结果表明，在处理不同的封闭侧设置和给料粒度分布时，该模型能够很好地预测破碎机的性能。

Fit-for-Purpose Model of HP500 Cone Crusher in Size Reduction of Itabirite Iron Ore

Cone crushers have a central role in the processing of quarry rocks, besides coarser ore preparation in several mineral processing plants. This is particularly true in the case of Itabirite iron ore preparation plants in Brazil, so optimizing their performance is of central importance for reaching maximum productivity of the circuit. The work presents results of modeling the HP500 cone crusher in operation in an industrial plant in Brazil (Minas Rio), from surveys carried out over a few years with different feeds and crushing conditions. A version of the Andersen–Whiten cone crusher model was implemented in the Integrated Extraction Simulator featuring a non-normalizable breakage response and a fit-for-purpose throughput model. The results demonstrate the good ability of the model to predict crusher performance when dealing with different closed-side settings and feed size distributions.
