三個主要的破碎耗功學說
在選礦廠中，電能的絕大部分用于破碎礦石。為了深入理解破碎礦石過程，評價破碎機械的效率，和找尋更有效的破碎方法，百多年來出現(xiàn)了很多有關(guān)破碎耗功的理論。其中有三個最主要的，為舉世所公認，在此將作介紹。
大家都知道，破碎過程是不會自動發(fā)生和不可逆的，必須外力對礦石作功，克服它的內(nèi)部質(zhì)點間的內(nèi)聚力，才能發(fā)生破碎。當外力對礦石作功使它破碎時，礦料的潛能也因此功的轉(zhuǎn)化而增加。因此，破碎耗功理論實質(zhì)上就是,闡明破碎過程的輸入功與破碎前后礦石的潛能變化之間的關(guān)系，從而明確輸入功是怎樣耗去的。破碎物料時,它的強度、給礦粒度、產(chǎn)品粒度和耗功，是直接易為人查覺的，因此各種功耗學說都必須確定出它們間的關(guān)系,這是各種破碎耗功學說的共同點。但因每一種耗功學說都從不同的角度看問題，所以它們的物理根據(jù)和導出的數(shù)學形式也就不同。

In mineral processing plants, the vast majority of electric energy used for crushing ore. To deeply understand the process of ore's broken, the efficiency evaluation for broken machinery, and seek more effective methods of broken, hundred years appeared many theories for crushing power comsumption. There are three major and universally recognized, and will be introduced here.

As we all know, the crushing process is not automatic and irreversible, it is necessary to do the work of the ore, to overcome its internal cohesion between particles can be broken. When the external force on the ore as power to make it broken, the potential of the mine, so that the transformation of power and so on. Therefore, broken power comsumption theory essence is to clarify the broken relationship between before and after the process of input power and broken ore potential changes, so as to clarify the input power is how consumption to the. Crushing material, its strength, to the ore particle size, the particle size of the product and power comsumption is direct and easy to check to feel, so various kinds of power theory must determine the relationship between them, which is all broken power comsumption theory have in common. But because each kind of theory of power comsumption are from a different point of view look at the issue, so their physical basis and derived the mathematical form is also different.
