CIR Series Low Pressure Down The Hole Hammer Drilling with Solid Steel Material
 
CIR Series Low pressure DTH Hammer for rock drilling machine
 
Introduction
 
CIR series DTH Hammer, a kind of valve equipped low air pressure hammer with a single piston, a plate valve and a central exhaust structure.
 
The compressed air is adopted as the driving force. To get a better performance and prevent dust pollution, some high-pressure water may be added into the air for wet rock drilling.
 
It is mainly featured in:  
1.The strong energy of single impact and the low energy consumption in rock crushing.  
2.The weight ratio of piston and bit almost reaches 1:1 to provide long effective acting time, which leads to the improved efficiency in rock crushing and the extended service life of the drilling tool.   
3.A good performance in central air exhaust and cutting discharge, which reduces the repeated crushing of rock.  
4.Acheck valves device is available to drill holes under water.  
The HR series DTH Hammer, an ideal drilling tool, is widely used in such industries relating to energy,construction,metallurgy,building etc.
