热力破碎是一种特别适合于难磨物料的工业粉碎过程，当必须避免在常规破碎和磨矿中设备磨损所造成的铁的污染时尤其如此。热力破碎的过程如下：首先将待破碎物料加热，然后将其骤冷（淬火），最后通过常规机械方法将物料破碎。事实上，加热步骤是一个预破碎过程。加热会引起矿物相的变化，同时还可以引起矿物和其它包含在孔隙和裂缝中的物质的体积变化。而骤冷引起矿物的突然收缩或相交，结果产生了大到足以破碎此固体的内应力。本文除了涉及Aaricola’sDeReMetallica这一最典型的热力破碎实例外，还包含有文献综述。本文论述不同的破碎机理，加热冲击、相变、内部体积的变化以及剩余粒间应力。然后本文叙述了热力破碎高纯石英的工业实践。只有采用像这样的无污染的破碎过程，将铁品位减少到低于500ppb（十亿分之五百）的目标才可能实现。最后，本文叙述了作者用石英所做的试验。加热温度和破碎石英所用的设备都是不同的，设备有球磨机、辊式破碎机和捏碎机。粒度分布和破碎产品的显微镜分析清楚地表明，破裂过程实际上发生在加热阶段。正因为如此，不同的最后破碎设备所产生的颗粒都具有相同的形状和类似的粒度分布。结论是热力破碎具有其潜在的利用价值，而且人们应当把注意力更多地集中在将上述的破碎
Thermal crushing is an industrial crushing process that is particularly well-suited for hard-to-grind materials, especially when it is necessary to avoid iron contamination caused by equipment wear during conventional crushing and grinding. The process of thermal crushing is as follows: the material to be crushed is first heated, then quenched, and finally crushed by conventional mechanical means. In fact, the heating step is a pre-crushing process. Heating can cause changes in the mineral phase while also causing changes in the volume of minerals and other materials contained in the pores and cracks. Quenching, on the other hand, causes a sudden contraction or intersection of minerals, resulting in an internal stress large enough to break the solid. In addition to Aaricola’s DeReMetallica this article is the most typical examples of thermal crushing, but also contains a literature review. This article discusses different crushing mechanisms, heating shocks, phase transitions, changes in internal volume, and residual intergranular stress. This article then describes the industrial practice of thermal cracking of high purity quartz. Only with a pollution-free crushing process like this could be achieved by reducing the iron grade to less than 500 ppb. Finally, this article describes the author’s experiment with quartz. Heating temperature and broken quartz equipment used are different, equipment, ball mill, roller crusher and crusher. Microscopic analysis of the particle size distribution and crushing products clearly shows that the rupture process actually takes place during the heating phase. Because of this, the particles produced by the different final crushing devices have the same shape and a similar particle size distribution. The conclusion is that the thermal crushing has its potential value, and people should focus more attention on the crushing
