A High Air Pressure Hammer is a drilling tool used in the mining, construction, and exploration industries to create holes in rock and other hard surfaces. It's often used in situations where traditional drilling methods might not be effective. The High Air Pressure Hammer operates by delivering high-frequency, high-impact blows to the drill bit, which in turn fractures the rock and creates a hole.
When it comes to High Air Pressure Hammer, the term refers to a type of hammer that uses compressed air at elevated pressures to drive the drilling process. Here's how it works:
Compressed Air Source: The drilling rig provides a source of compressed air. This air is typically generated by a compressor and delivered to the High Air Pressure Hammer through hoses.
Inside the High Air Pressure Hammer: The compressed air enters the DTH hammer and is directed toward the bottom of the hammer assembly.
Piston Impact: Inside the High Air Pressure Hammer, there's a piston that's driven by high-pressure air. This piston moves rapidly up and down due to the alternating pressure of the air. The piston strikes the back of the drill bit with high impact and frequency.
Drill Bit Action: The repeated impacts from the piston cause the drill bit at the bottom of the hammer to chip away at the rock or material being drilled. The high impact and frequency of blows help break the rock into smaller fragments.
Removal of Cuttings: As the drilling process continues, the cuttings (small pieces of rock or material) are cleared from the hole by the flow of compressed air. This ensures that the drill bit has a clear path to continue drilling.
The term "high air pressure" refers to the increased pressure of the compressed air being used in the DTH hammer. Higher air pressures can lead to more powerful and efficient drilling, as they deliver stronger impacts to the drill bit, allowing it to penetrate harder rock formations more effectively.
High Air Pressure Hammers are often chosen when drilling in challenging geological conditions where regular High Air Pressure Hammer might struggle to make progress. These hammers are designed to handle higher pressures and are equipped with sturdier components to withstand the increased forces generated during drilling.
