Steam pressure crushing method
  • The crushing agent of the non-chemical composition is heated to high temperature by the external stimulus with an initiator, and the metal solid is instantly replaced by the metal vapor to generate a volume expansion impact pressure. By generating and breaking the pressure above the breaking strength of the rock, it is a micro vibration excavation method that can maintain the work flow of the existing gunpowder blasting against the vibration, noise and scattering that are raised during the gunpowder blasting work and can perform more sedentary and eco-friendly work.
