在教科书和技術書上,通常把計算破碎和磨碎鑛石的能量消耗的假說理解為破碎定律。这些定律,通常是用依次分割成立方体的例子和级數比較的方法(譯註)來解釋的,这些方法卽繁複又不十分確鑿。用分析法得出的結論不僅簡單且而又比較確鑿。鬆散物料的單位表面積用下式計算: 式中d為在鬆散混合物中物料塊的平均直徑,δ為 In textbooks and technical books, the hypothesis of calculating the energy consumption of crushing and grinding ores is often understood as the law of fragmentation. These laws are usually explained by the examples of successive partitioning into cubes and the comparison of progression numbers. These methods are complex and not very conclusive. The conclusions drawn from the analysis are not only simple but also conclusive. The unit surface area of ​​loose material is calculated using the following formula: where d is the average diameter of the mass in the loose mixture, and δ is
