What is the principle of hydraulic breaker?
The Science Behind a Hydraulic Hammer | Breaker
Pascal's law, which is a mechanical principle in mechanics, is the basic function of the hydraulic hammer. By putting pressure on one part of a fluid, it transfers the pressure to all areas of the fluid, which multiplies the force.
Application
Breakers for mine, quarry, site, and trench breaking!
At present, the breaker has been widely used in secondary crushing in mining areas by virtue of its advantages, completely replacing secondary blasting for large-block crushing. In mining operations, the application of hydraulic breakers under certain special restrictions presents unique advantages, especially in selective mining and non-blasting mining operations, and it is a new mining method.
