Top hammer drilling feature
1. The most suitable for hole diameter between 25–127 mm.
2. Generally, the hole depth is less than 25 meters.
3. Adapt to a stable and uniform hard rock.
4. The slag flushing medium is compressed air or water.
5. High efficiency in shallow holes drilling, the deeper the lower efficiency.
6. Most easily to skew in these three drilling methods.
Kingdrilling rock drill tools application:
1. Mining and quarrying drilling
2. Mining exploration drilling
3. Piling and foundation drilling
4. Water well drilling
5. Geothermal drilling
6. Horizontal directional drilling
FAQ:
1. What is top hammer drilling?
In Top Hammer Drilling the hammer produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit.
2. Is top hammer drilling vs down-the-hole drilling?
The primary difference between the top hammer and down-the-hole drilling methods is where the hammer is attached. The hammer in the industrial equipment makes contact with the bit during the down-the-hole drilling method. The top hammer drilling method's activity is concentrated at the very top of the drill string.
3. How does the Top Hammer Drilling work?
The percussive force of the top hammer drilling produced by the piston of the pump in the hydraulic drilling rig, it is transmitted to the drill bit via shank adaptor and drill pipe, This is the difference between DTH drilling. Meanwhile, the percussion system drives the drilling system rotation. When the stress wave reaches the drill bit, the energy is transmitted to the rock in the form of bit penetration. The combination of these functions enables drilling holes into the hard rock, and the air compressor only performs dust removal and slagging in top hammer drilling.
The combination of these functions enables drilling holes into the hard rock, and the air compressor only performs dust removal and slagging in top hammer drilling.
Impact energy multiplied by impact frequency together creates the percussive output of the drifter. However, usually, top hammer drilling used for hole diameter maximum 127mm, and hole depth less than 20M, which in high efficiency.
4. What is a button bit?
Button bits, or roller cones, have rotating cones that contain tungsten carbide inserts. Tricone, or three cone bits, are the most common; however, manufacturers continue to make two cone and one cone bits.
