4 Inch Mission 40 DTH Hammer

1. Precisely Pressure Control

Optimizing piston structure design to fully leverage air pressure and maximize air compressor efficiency. Simultaneously enhancing the airflow system directs the majority of pressure directly to the piston, significantly reducing pressure loss and achieving highly efficient air energy utilization.

2. Superior Water Resistance

The piston must operate effectively in water-rich environments, making the precise balance between air utilization efficiency and waterproof sealing performance critical. Equipped with a professional sealing system, it effectively blocks water ingress without compromising air pressure transmission or causing any pressure drop, ensuring stable operation under working conditions.

3. Drilling Velocity

Throughout the drilling operation, the speed must be maintained at 1 m/min or higher until the borehole reaches a depth of 300 meters. This requirement is achieved by precisely balancing impact energy and frequency, ensuring drilling stability and continuity to guarantee efficient progress of the construction schedule.

4. Impact Mechanism

Appropriately balanced piston weights allow the frequency and force of impact operations to be precisely regulated. The proportion of the counterweight piston determines the impact frequency. If the piston is too light, the drilling bit may be subjected to excessive stress. Conversely, if the frequency is too low, the drilling efficiency will be reduced due to improper piston weighting. The core function of piston counterweighting is to balance the distribution of impact energy. Only by setting it within a reasonable range can high, stable drilling rates be consistently maintained across various rock formations.

5. Durability and Maintainability

The piston is manufactured from high-toughness, wear-resistant materials, capable of withstanding continuous impacts in various harsh mining environments. The down-the-hole hammer features simplified component design, with core parts that are easy to disassemble and replace, ensuring convenient maintenance and rapid restoration of optimal equipment performance.

The 4-inch DTH hammer incorporates a high-efficiency, durable piston structure that supports high-speed drilling operations while maintaining stable, efficient performance in challenging conditions such as water-bearing formations. All components exhibit exceptional durability, operate without pneumatic pressure loss, and feature straightforward maintenance and replacement procedures.

6. Airflow and Pressure Management

The piston is designed for continuous operation at pressures of up to 35 bar. With a standard airflow capacity, the air velocity can reach 600 liters per second (l/s). This ensures sufficient power delivery under demanding conditions, enabling efficient drilling and maintaining optimal performance.
