本文论述磨矿静态数学模型和用电子计算机进行模拟的程序。对我国选矿厂粗精矿(或中矿、尾矿)再磨的流程,即预先分级和控制分级相结合,由一台球磨机和一台或多台水力旋流器组成的流程,进行静态数字模拟。以我国某铅锌矿选矿厂为例,介绍了具体应用方法和步骤,并列出模拟和实测结果的对比。 This article discusses the static mathematical model of grinding and the computer simulation program. The process of regrinding the rough concentrate (or middle mine and tailings) in our ore dressing plant, that is, the combination of pre-classification and control classification, a process consisting of a ball mill and one or more hydrocyclones, simulation. Taking a lead-zinc ore concentrator in China as an example, the specific application methods and steps are introduced, and the comparison between simulation results and measured results is given.
