The Better Solution in Rock Breaking
The Boulder BusterTM is a compact, cost effective and portable piece of equipment which is extremely useful in splitting and breaking rocks, boulders as well as the demolition of concrete structures. The sheer convenience if operation and low operating costs make the Boulder BusterTM the first choice in standby rock breaking equipment.
Rock Breaking Procedure
The boulder buster is a non-detonating rock breaking tool utilising propellant technology. A pressure impulse is generated in the tool by a cartridge filled with propellant. The pressure impulse is directed via a barrel into an incompressible fluid column (water or gel) placed in a pre-drilled hold in the rock.
The success of the system results from the specific propellant technology used. The unique characteristics of the propellant and cartridge design results in a rapidly developing pressure wave. this impulse pressure (transmitted by the fluid column) starts the propagation of the fractures in the direction of stress concentrations and the nearest free face. The static pressure developed by the propellant causes further mechanical stress on the rock resulting in the tensile fracturing of the rock. The direction of breaking can be controlled by the drilling pattern or by notching the holes.
Rock Breaking: Hard Rock (100 to 350 MPa)
