摘要:

磨矿与分级是选矿厂金矿加工流程中必不可少的工序,实现该过程的优化与生产控制对节约资源、提高选矿厂经济效益具有重要意义。针对国内某金矿选矿厂的两段磨矿分级作业流程,建立了磨矿分级过程数学模型。为了提高数学模型的使用效率,以仿真软件ExtendSim为平台,开发了选矿厂磨矿分级过程仿真系统,并介绍了该仿真系统的设计与开发,包括系统结构与运行机制设计、系统功能设计及系统数据库与通讯接口设计。以该仿真系统为平台进行仿真试验,可研究不同工艺条件下的磨矿分级过程生产情况。在仿真实例中,以球磨机的转速率、填充率和料球比为影响因素,通过均匀设计试验法设计仿真试验,以快速地确定较优的试验方案,并以该试验方案的工艺参数值为基础,进行单因素仿真试验以进一步确定最佳的工艺参数值。通过对比分析多组仿真试验结果,得出该磨矿分级过程在某生产计划与入磨矿石粒度条件下的最佳球磨机工艺参数,为实际生产提供科学的参考依据。

Abstract:

The grinding and classification process is an important process of gold ore processing.Realizing the optimization of grinding and classification process is significant to save resources and improve the economic benefit of concentrator.By studing on the grinding and classification process of a domestic gold concentrator,the mathematical model is set up and a simulation system of grinding and classification process is developed based on the simulation software ExtendSim.The structure and functions of simulation system are introduced in detail.As a platform of simulation experiment,the simulation system could help to study the production status of grinding and classification process with different technological parameters.In the simulation example,some simulation tests are designed based on uniform design experimentation to ensure the optimal experiment scheme quickly which choose the rotational speed,the filling ratio and the powder-to-ball ratio of ball mill as factors.In order to obtain the best technological parameters of grinding and classification process,a subsequent series of single factor simulation experiments are implemented.Comparing the multi-bank simulation test results,the optimal parameters of ball mill is obtained under a certain condition of production plan and raw material properties.The simulation results could provide effective reference basis for practical production.
