Co2 rock breaking system
The Co2 rock breaking system is a new type of rock breaking equipment that can replace explosive blasting. There is no vibration, shock wave, open flame, or harmful gas during the process of using Co2 rock breaking system, which is very safe and convenient. Most importantly, it can be reused, which significantly reduces the construction cost. The emergence of Co2 rock breaking system perfectly solves the problem of the prohibition of blasting in mines and rock excavation and the low efficiency of hydraulic breakers. It has been widely used in mining, quarrying, highway construction, foundation construction, tunnel excavation and other fields.

Product Principle
Below the critical temperature (-31.1 degrees Celsius), Co2 is in the state of liquid Co2. When the temperature gets higher, it will become gas and its volume will expand. The Co2 rock breaking system takes advantage of this feature. During on-site construction, put rock breaking steel pipes into the pre-drilled holes. After starting initiator, liquid Co2 will vaporize at once and its valume will expand 600 times. Hence, strong energy is released in confined space，which will burst sealing gasket at the end of vent head, releasing strong stress wave to breaking up surrounding rocks.
