磨矿试验资料是选择磨矿流程的重要依据。对于常规磨矿流程的结构、性能以及介质的类型和作用，人们已经有了较清楚的认识。但对于不同矿石用不同的磨矿设备磨矿的效果、生产能力、能耗和钢耗等均无确切的现成规律可循，尤其是

Grinding test data is an important basis for selecting grinding process. For the structure, performance and the type and function of the conventional grinding process, people have a better understanding of the process. However, there are no specific rules to be followed for different ore grinding equipment, such as the effect, production capacity, energy consumption and steel consumption.

在采用自磨，流程时，必须事先摸清矿石对自磨的适应情况，自磨介质的适应性基准值越大，则矿石对自磨的适应性越强。如果该值小于1，则矿石不适于自磨；如果矿石的功指数比率值太小，则说明介质不足。在对试验室测定的有关参数进行多方面的综合比较的基础上，进行半工业或工业性自磨试验，是合理选择自磨磨矿流程的必要途径。

In the use of self grinding process, the need to find out the adaptation of the ore to the self grinding, the greater the adaptability of the self grinding medium, the higher the ore to the self adaptability. If the value is less than 1, the ore is not suitable for self grinding; if the value of the ore is too small, the media is not enough. In the laboratory determination of the relevant parameters were based on a comprehensive comparison of various, autogenous grinding test of semi industrial and industrial is a reasonable choice since the necessary means for the grinding process.

为了选矿厂顺利建设，在进行磨矿流程选择时，还应了解建厂地区的技术、经济和交通地理条件、运输条件，磨矿介质、衬板和电能的来源及价格。此外，选用磨矿流程应兼顾到设备操作管理方便，运转可靠，便于维修检查，并尽量降低粉尘、噪音及电磁波等因素对环境的污染。

In order to construct the ore dressing plant, the technology, economy and traffic conditions, transportation conditions, the source and price of the medium, lining board and electric energy in the construction area should be understood. In addition, the selection of grinding process should take into account the equipment operation and management is convenient, reliable operation, easy maintenance inspection, and minimize dust, noise and electromagnetic wave and other factors on the environment pollution.

总之，影响磨矿过程的因素较多，相互之间的关系较复杂，通过常规的研究手段一般很难全面掌握。目前主要根据在选矿厂进行的半工业或工业试验对比各流程的基建投资和生产费用，最后，才能选择出最合适的磨矿流程，并得到最佳的预期效果。由于碎磨过程数学模型的建立，电子计算机的应用和发展，国内外正在逐步积累这方面经验。

In short, the factors that affect the grinding process are more and more complex, which is difficult to master in general. At present, according to the comparison of the semi industrial and industrial test in the mineral processing plant, the investment and production cost of the infrastructure investment and the production cost is the most suitable. Because of the establishment of the mathematical model of grinding process, the application and development of the electronic computer, and the experience in the domestic and foreign are gradually accumulated.

根据各种矿石的磨矿分级技术指标，以及磨矿流程和操作过程的技术参数，可建立电算程序。在应用时，只需将矿石的最基本的磨矿技术数据（ 有时是用批次磨矿试验数据）送入电子计算机内，通过数字模拟可以较准确地评价和选择磨矿流程。

According to the technical index of the grinding classification of various ores, and the technical parameters of the grinding process and the operation process, the calculation procedure can be established. In the application, the most basic ore grinding technology data (sometimes using batch grinding test data) into the electronic computer, through digital simulation can be more accurate evaluation and selection of grinding process.
