Abstract
A new technique of inducing crushing of rocks and related brittle solids by a single fracture process using thermal shock principles has been developed by the Bureau of Mines in cooperation with the U.S. Army advanced material concepts agency. Thermal crushing of brittle solids is feasible by thermal shock techniques. Fragmentation is initiated by tensile thermal stress concentrations of material defects within the interior of the solid. The magnitude and distribution of thermal stresses and, therefore, the crushed product sizes can be controlled by varying the heating conditions. Increasing the thermal shock intensity reduces the size of the crushed fragments and the energy required for fragmentation.
