Gaea High pneumatic DTH hammer

The down-the-hole hammer is a component of the down-the-hole drilling rig and belongs to the working device of the down-the-hole drilling rig. DTH hammer is divided into low wind pressure DTH hammer, medium wind pressure DTH hammer and high wind pressure DTH hammer.

It is widely used in hole-forming operations in mines and water conservancy, hydropower, highway, railway, national defense, construction and other projects where metallurgy, coal, chemicals, and building materials are not busy. It is suitable for dry, water and wind mixing and blast hole water gushing wet operations with reliable working performance , Is the ideal drilling and blasting equipment today.

The working principle of the hammer: At the beginning of the impact stroke, the piston and the valve plate are in the extreme upper position, and the compressed air enters the upper cavity of the cylinder through the radial holes of the valve cover and valve seat, pushing the piston to move downward at high speed to impact the drill bit. When the piston travels to the bushing and the spline groove is closed, the pressure in the lower cavity starts to rise, so the center hole of the upper end of the piston leaves the valve rod, the upper cavity is vented to atmosphere, the pressure is reduced, and the working stroke ends. After the piston hits the tail of the drill bit, the valve plate reverses its direction due to the pressure difference between the upper and lower sides, and the piston repeats its return stroke movement.


The DTH drilling rig is composed of a slewing mechanism, a lifting mechanism, a pushing mechanism, a supporting mechanism and an impact mechanism. In rock drilling operations, the DTH hammer is submerged into the hole to reduce the energy loss caused by the impact energy transmitted by the drill rod, thereby reducing the impact of the hole depth on the drilling efficiency.


From the appearance alone, it is difficult to distinguish the difference between the top hammer and the DTH type at first glance. In fact, the biggest difference between the two lies in the location of the impact force, which is why there are two forms of appearance.


Gaea offers the market’s most comprehensive range of DTH hammers(drilling hammers). we offers Down-the-Hole hammer solutions for water well drilling, miners and quarry drilling and for the construction, oil and gas industries. We even offer environmentally friendly water-lubricated hammers and the reverse circulating RC hammers aimed at Green Field exploration. 


Our High pneumatic DTH hammer advantage:

1. The valveless gas distribution method is adopted, and the gas distribution is reliable.

2. The piston structure is simple and not easy to damage.

3. Ideal energy transfer, fast drilling speed, low air consumption and low fuel consumption.

4. Few parts used, simple structure, and all parts are hardened, so it has a long working life, few failures and convenient maintenance.

5. The joint and the brazing sleeve are connected with the outer steel by multi-threaded thread, which is easy to disassemble.
