A new concept of thermal crushing of hard rocks is examined in this study. The theoretical methods developed to analyze thermal stresses and fragmentation induced by partial and complete surface heating of rock blocks are correlated with experimental results. A three-dimensional state of tensile stresses induced in the rock specimen interior during surface heating initiates fragmentation.

Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones ...

Thermal spalling drills such as jet-piercing and forced-flame drills heat rocks to 370 to 540°C (700 to 1000°F) to create thermal stresses that spall the rock ().These devices have limited application because most rocks will not thermally spall (Maurer, 1968, 1980). Melting and vaporization drills utilize high-temperature devices such as lasers or electron beams to melt and vaporize rock ().
