磨礦試驗資料是選擇磨礦流程的重要依據(jù)。對于常規(guī)磨礦流程的結(jié)構(gòu)、性能以及介質(zhì)的類型和作用，人們已經(jīng)有了較清楚的認識。但對于不同礦石用不同的磨礦設(shè)備磨礦的效果、生產(chǎn)能力、能耗和鋼耗等均無確切的現(xiàn)成規(guī)律可循，尤其是
在采用自磨，流程時，必須事先摸清礦石對自磨的適應(yīng)情況，自磨介質(zhì)的適應(yīng)性基準值越大，則礦石對自磨的適應(yīng)性越強。如果該值小于1，則礦石不適于自磨；如果礦石的功指數(shù)比率值太小，則說明介質(zhì)不足。在對試驗室測定的有關(guān)參數(shù)進行多方面的綜合比較的基礎(chǔ)上，進行半工業(yè)或工業(yè)性自磨試驗，是合理選擇自磨磨礦流程的必要途徑。
為了選礦廠順利建設(shè)，在進行磨礦流程選擇時，還應(yīng)了解建廠地區(qū)的技術(shù)、經(jīng)濟和交通地理條件、運輸條件，磨礦介質(zhì)、襯板和電能的來源及價格。此外，選用磨礦流程應(yīng)兼顧到設(shè)備操作管理方便，運轉(zhuǎn)可靠，便于維修檢查，并盡量降低粉塵、噪音及電磁波等因素對環(huán)境的污染。
總之，影響磨礦過程的因素較多，相互之間的關(guān)系較復雜，通過常規(guī)的研究手段一般很難全面掌握。目前主要根據(jù)在選礦廠進行的半工業(yè)或工業(yè)試驗對比各流程的基建投資和生產(chǎn)費用，最后，才能選擇出最合適的磨礦流程，并得到最佳的預期效果。由于碎磨過程數(shù)學模型的建立，電子計算機的應(yīng)用和發(fā)展，國內(nèi)外正在逐步積累這方面經(jīng)驗。
根據(jù)各種礦石的磨礦分級技術(shù)指標，以及磨礦流程和操作過程的技術(shù)參數(shù)，可建立電算程序。在應(yīng)用時，只需將礦石的最基本的磨礦技術(shù)數(shù)據(jù)（ 有時是用批次磨礦試驗數(shù)據(jù)）送入電子計算機內(nèi)，通過數(shù)字模擬可以較準確地評價和選擇磨礦流程。
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，流程時，必須事先摸清礦石對自磨的適應(yīng)情況，自磨介質(zhì)的適應(yīng)性基準值越大，則礦石對自磨的適應(yīng)性越強。如果該值小于1，則礦石不適于自磨；如果礦石的功指數(shù)比率值太小，則說明介質(zhì)不足。在對試驗室測定的有關(guān)參數(shù)進行多方面的綜合比較的基礎(chǔ)上，進行半工業(yè)或工業(yè)性自磨試驗，是合理選擇自磨磨礦流程的必要途徑。
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.

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.

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.
根據(jù)各種礦石的磨礦分級技術(shù)指標，以及磨礦流程和操作過程的技術(shù)參數(shù)，可建立電算程序。在應(yīng)用時，只需將礦石的最基本的磨礦技術(shù)數(shù)據(jù)（ 有時是用批次磨礦試驗數(shù)據(jù)）送入電子計算機內(nèi)，通過數(shù)字模擬可以較準確地評價和選擇磨礦流程。
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.
