The Ramair air flush system is designed to prevent dirt from entering the hammer housing and keep the tool grease flowing towards the lower tool bushing. It's most beneficial in applications where the material is highly abrasive and dusty. Ramair is also recommended for applications where the hammer working position is horizontal or above, such as tunneling and scaling applications.
Demolition of standing buildings and structures.
Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
Tunneling with a hydraulic breaker is similar to primary breaking. It is useful in weathered rock conditions, especially in operations with ristricted clearance.
Scaling is removal of loose material from the tunnel roof and walls to prevent accidents by falling rocks.
Hammer fitted to an excavator working directly in a bench to breaks away rock which can then be removed by truck. This is most commonly used where blasting is not allowed.
When blasted rock is too big for the feeder or crusher, secondary breaking is needed to get the boulders down to size. The type of rock dictates the effectiveness of the process, with brittle rock giving the best performance.
The metallurgical industries can be broadly divided into primary, secondary, and miscellaneous metal production operations.
