Ｒｉｔｔｉｎｇｅｒｓ粉碎定律发表于１８５７年，从那时起，出现了不少粉碎理论和定律。虽然Ｒｉｔｔｉｎｇｅｒｓ定律一直是最好的通用粉碎理论之一，但它和广泛应用的Ｂｏｎｄ“第三粉碎理论”一样，仅在一些特定的条件下才是正确的。研磨试验表明，碎磨过程中，筛上物的减少通常可看作为一阶过程（或线性过程——译者注＊通常还认为，经粉碎的产品具有一定的粒度分布，而这种分布符合ＲＲＳＢ公式。当“一阶定律”应用于不同筛孔时，便可得出符合Ｒｏｃｉｏｎ－Ｒａｍｍｌｅｒ公式的通用粉碎理论．多方比较表明，最重要的那些粉碎定律是从通用粉碎理论引出的适用于特定情况的逻辑结果。在闭路研磨中，建议对回路中的分级机采用一个效率系数，这也是以“筛上物的减少是一个一阶过程”为基础的．最终结果是得出一种综合粉碎理论，用以计算在开路或带分级机的闭路中，在不同的筛孔上，研磨到不同的筛上物时的单位能耗。
Rittingers’s law of crushing was published in 1857, and since then a number of crushing theories and laws have emerged. Although Rittingers’s law has always been one of the best general smashing theories, it is just as well as the widely used Bond “third smashing theory,” only under certain conditions. Grinding tests have shown that reduction of oversize during crushing can often be considered as a first order process (or linear process). It is also generally accepted that a comminuted product has a particle size distribution consistent with RRSB formula The general smashing theory according to the Rocion-Rammler formula is obtained when the “first-order law” is applied to different sieve openings and the multi-comparisons show that the most important of these smashing laws are those derived from general smashing theory that apply to specific The logical result of the situation In closed loop grinding, it is advisable to apply an efficiency factor to the classifier in the loop, which is also based on “the reduction of the oversize is a first order process.” The end result is a comprehensive crushing Theory to calculate the energy consumption per unit of time when grind- ing to different sieve contents in open circuits or closed circuits with classifiers on different sieves.
