Description

CIR70 CIR90 CIR110 CIR150 Low Air Pressure Down The Hole DTH Hammer for Stone Quarry Drilling


Low air pressure DTH hammer

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 prevent dust pollution and get a better performance, some high-pressure water may be added into the air for wet rock drilling.


Main Characteristics:

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 tools;

3.A good performance in central air exhaust and cutting discharge, which reduces the repeated crushing of rock;

4.A check valve device is available to drill holes under water

The CIR series DTH hammer, and ideal drilling tools, is widely used in such industries relating to energy,transportation,metallurgy,building etc.
