Introduction :
CIR90 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.
Technical Data:
| Length (less bit) | Weight(less bit) | External diameter | Bit shank | Hole range | Connection thread |
| 800mm | 19.00kg | ∅80mm | CIR90 | ∅85-∅110 | T48×10×2 |
| Working Pressure | Impact rate at 0.5 Mpa | Recommended rotation speed | Air consumption | ||
| 0.5Mpa | 0.7Mpa | ||||
| 0.5-0.7Mpa | 14HZ | 25-40r/min | 6.5m³/min | 8 m³/min | |
Feature:
1. The strong energy of single impact and the low energy consumption in rock crushing
2. The wight 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 cuttings discharge, which reduces the repeated crushing of rock
4. A check valve device is available to drill holes under water
Usage:
CIR90 dth hammer an ideal drilling tool, is widely used in such industries relating to energy, transportation, metallurgy, building etc.
