Structure of top hammer drilling rig

Our Full hydraulic surface top-hammer drilling rig has a perfect combination:


1. Hydraulic rock drill

YAMAMOTO YH-100 hydraulic rock drill is the core component of the rig, which directly affects the reliability and service life of the whole machine. YH-100 rock drill is manufactured in Japanese factory, with reliable quality, sturdy and durable. Since 1979, it has provided a series of hydraulic rock drills to the world famous drill rig manufacturers. The hydraulic rock drill has an impact power of 20.6kw and an impact frequency of up to 2500bpm, which is very suitable for drilling operations with a hole diameter of 76mm ~ 127mm.


2. Compressor of Full Hydraulic Top Hammer Surface drilling rig

American Sullivan-Palatek is a world-renowned manufacturer of screw compressors, and its screw assemblies are well-known for their high efficiency, reliability and long life. The compressor discharge volume is 10.5 m³/ min, and the discharge pressure is 10.5 bar. Even under complicated geological conditions, it can provide sufficient gas for cleaning holes and smoothly discharge rock cuttings.


3. Control System of Full Hydraulic Top Hammer Surface drilling rig

The unique and easy-to-control rock drilling control system can automatically adjust the propulsion speed, propulsion pressure, slewing torque and impact pressure according to the rock conditions, to achieve the best working condition, and eliminate abnormal accidents such as stuck thread wear. The components of the hydraulic system are selected from domestic and abroad well-known manufacturers to ensure the reliability and durability of the whole machine.

As one of the professional top hammer surface drill rig manufacturers, HBXG understands your drilling equipment needs, which is why drilling rigs are perfectly engineered for optimum precision, efficiency and safety. Whether you're drilling production holes, presplit holes, or anything in between, all of our rock drilling machines are built with safety in mind.

Top hammer drilling principle

1. When the piston hits the shank, kinetic energy in the piston creates a compressive wave in the string of drilling tools, that will cause the bit to penetrate the rock

2. Piston velocity at impact ≈ 10m/s but the compressive wave in the drill steel travels at a velocity of 5180 m/s (velocity of sound in steel)

3. The bit is forced forward and penetrates the rock around 1.0 mm

4. Part of the energy not used to penetrate the rock goes back as a tensile wave and part of it as a compressive wave
