Design And Preliminary Testing Of A Thermomechanical Rock Fragmentation Apparatus, Gary Earl Fenton
Masters Theses
"The design characteristics of equipment to thermally weaken and mechanically fragment hard rock were developed and the apparatus constructed. An initial investigation of thermo-mechanical fragmentation was conducted on Missouri red granite. The particles from the fragmentation tests were sized and this analysis was used in the Rittinger theory to calculate surface area breakage energy. It was found that the application of thermal energy could reduce the surface area breakage energy per unit volume of material removed by as much as 41 percent. The use of kerfs in the rock increased the amount of material removed and permitted larger particles to …
