Product Description
DTH hammer, as an underground hammer drilling equipment, is specially designed for open-pit mines, quarries, water conservancy projects and other operations, including low - pressure, medium - low pressure, high - pressure DTH hammers and RC hammers. The low - pressure DTH hammer stands out for its high - efficiency rock crushing and central exhaust and slag removal capabilities. It has high impact energy, low energy consumption, and a weight ratio of piston to drill bit of nearly 1:1, which improves crushing efficiency and extends the life of drilling tools. Equipped with inspection valve device, suitable for water source drilling operations. The DTH hammer has powerful functions and efficient operation. It is an ideal choice for the drilling industry, helping to improve work efficiency and reduce operating costs.

Machine Advantages
High - pressure DTH drilling rigs show many advantages in drilling operations. First, its valveless air distribution system increases reliability and simplifies operation. Secondly, the drilling rig’s piston has a simple design, thus extending its service life. More efficient energy transfer not only increases drilling speed, but also significantly reduces air and oil consumption. In addition, the reduction in the number of internal parts makes the structure simpler, and heat - treated parts improve the overall durability and reduce the probability of failure, making maintenance more convenient. Finally, the top connector, drive ferrule and external cylinder of the drilling rig are connected with multi - stage threads, making them easy to disassemble, further improving operating efficiency. These characteristics make high - pressure DTH drilling rigs an ideal choice for efficient and reliable drilling operations under complex geological conditions.
