4" Super Dominator Mission40 DTH hammer ( 2024 new )
- Biggest Benefits : This 2024 new DTH hammer uses a non inner cylinder DTH hammer , which has simple gas distribution, low air consumption, fast impact frequency, and long service life.
ProDrill™ DTH product line comes with a full range covering 4, 5, 6, 7 and 8-inch hammers. The ProDrill™ DTH hammer is built to be a reliable workhorse - combininghigh performance and efficiency with a rugged construction. lts easy-to-service design allows for minimal service time and higher productivity.
New DTH hammer 4" design with NON-INNER CYLINDER
Conventional DTH hammer 4" design with INTERNAL CYLINDER
Features and advantages:
1. Reasonable utilization of air pressure.
The utilization rate of air pressure, the design of the piston, and the maximum utilization of air compressor air pressure. This involves optimizing the airflow system to ensure that most of the air pressure is directed onto the piston, thereby reducing air pressure waste.
2. Water proofness:
The piston must be able to operate efficiently in high water environments. The balance between air efficiency and water resistance is crucial. It should have a sealing system to prevent water from entering without affecting the air pressure even air drop.
3. Drilling speed:
The drilling speed must be maintained at a rate exceeding 1 meter per minute (m/min) throughout the entire drilling process, up to 300 meters. This requires achieving the optimal balance between impact energy and frequency to achieve steady progress.
4. Impact mechanism:
A reasonable piston weight is used to balance the frequency and force of each impact. The frequency depends on the lighter and heavier pistons, which can cause excessive stress on the drill bit. However, if the frequency is slower, the weight of the piston may reduce drilling efficiency.
The weight of the piston is used to balance energy distribution. The weight of the piston is reasonable, which can ensure the effective drilling rate into the rock layer.
5. Durability and maintainability:
Pistons should be made of high toughness and wear resistant raw materials to withstand harsh drilling conditions.
The design of the DTH hammer must have simple accessories, easy maintenance, and basic components that are easy to disassemble and replace, in order to restore the performance of the hammer.
A 4-inch impactor should be an efficient, durable piston that can maintain high drilling speed and operate effectively in harsh environments with water. The components are durable, do not drop air pressure, easy to maintain, and replaceable, ensuring that the down-the-hole is properly scrap
6. Air flow and pressure treatment:
The piston should be able to operate continuously at a pressure of up to 35 bar. The airflow capacity is normal, reaching an airflow speed of 600 liters per second (l/s) to ensure sufficient power for effective drilling and optimal performance under harsh drilling conditions.
