影响岩石碎磨特性的因素很多,本文着重于讨论颗粒形状和再结晶作用的影响。文中指出不规则形状的颗粒通常都会强化岩石和阻碍矿物的解离;也指出了霞石正长岩中沿晶粒边界的细粒长石层的再结晶作用为什么会强化岩石。因而使之更难碎磨;最后一个实例讨论了石英岩的矿物结构与碎磨特性之间的关系,并提出了一种可能的方法以解释它们的热机械特性和碎磨特性差异的主要原因。 There are many factors that affect rock crushing characteristics. This article focuses on the effects of particle shape and recrystallization. It is pointed out that irregularly shaped particles usually strengthen the rock and impede the dissociation of the mineral. It also shows why the recrystallization of the fine-grained feldspar layer along the grain boundary in nepheline syenite reinforces the rock. Thus making it harder to fragment; the last example discussed the relationship between the mineral structure and crushing characteristics of quartzite and suggested one possible way to explain the differences in their thermomechanical and crushing characteristics .
