SP480 DTH Hammer

SP480 DTH Hammer
Powerful Down The Hole Drilling Solution For Mining And Construction

The SP480 DTH Hammer is an advanced pneumatic drilling component designed to provide efficient and reliable rock-breaking performance in demanding drilling environments.

As a key component of a DTH drilling system, the hammer is installed behind the drill bit and uses compressed air to drive the piston, generating powerful impact energy directly at the bottom of the borehole. This design minimizes energy loss and improves drilling efficiency, especially in hard rock formations.

The SP480 DTH Hammer is widely applied in:

Mining operations
Quarry blasting
Marble and stone extraction
Water well drilling
Foundation construction
Rock excavation projects

With optimized internal structure, durable materials, and efficient energy transmission, the SP480 provides stable drilling performance while reducing operating costs.

Advanced DTH Hammer Technology

The SP480 DTH Hammer adopts modern pneumatic impact technology to achieve efficient rock penetration.

Working Principle

During drilling operation:

Compressed air enters the hammer through the drill string.
Air pressure drives the internal piston movement.
The piston creates repeated impact forces.
Impact energy is transferred directly to the drill bit.
Rotation and impact together break the rock formation.

This direct impact method provides:

High impact efficiency
Faster drilling speed
Lower energy loss
Better hole accuracy
Improved drilling productivity
High Impact Energy Performance

The SP480 DTH Hammer is designed to deliver powerful impact performance for challenging geological conditions.

Performance Advantages
Strong Rock Breaking Capability

The hammer generates large impact energy to penetrate:

Granite
Limestone
Marble
Basalt
Hard rock formations
Stable Impact Frequency

Optimized piston movement ensures consistent drilling performance.

Efficient Energy Transfer

The short distance between hammer and drill bit improves impact efficiency.

Durable Internal Structure

The SP480 DTH Hammer uses high-quality materials and precision manufacturing technology to improve reliability.

Main Components
