Top Hammer Drilling Tools

Top rock drillingtools is a kind of rock tool consumables widely used in top hammer drilling applications, such as open-pit mining, quarrying, underground mining, rock bolting, tunneling, and production drilling. The top hammer rock drilling toolsinclude four parts: Drill bit, Drill rod, Shank Adapter, and Coupling Sleeve.

Top Hammer Rock Drilling Tools From Litian

Litian is a professional manufacturer of high-quality top hammer rock drilling tools with optimal drilling hole quality, high stability, and long service life. The top hammer toolsare designed and produced to transmit high-frequency impact energy into the rock and minimize energy loss to improve the rock breaking rate, penetration rate, and productivity.

Litian provides standard and heavy-duty series top hammer drilling rig tools, suitable for drilling in soft rock, medium-hard rock, hard rock, and various complex mixed rock working conditions. The drill bit, drill rod, coupling sleeve, and shank adapter are connected by their threads to form a rock drill string. The commonly used thread forms include rope thread (R25, R28, R32, R35, R38, SR28, SR35) and trapezoidal thread (T38, T45, T51, ST58, ST68, GT60).

Litian Top Hammer Rock Drilling Tools FAQs

Which drilling rigs can our drilling rig tools be used for?

Our drilling rig tools and mining machine parts are suitable for top hammer long hole drill rigs, rock support drill rigs, cable-bolting rigs, underground drill rigs, tunneling jumbos, narrow vein drill rigs, development drill rigs, surface top hammer drill rigs, dimensional stone drill rigs, and all other drilling rigs that use the way of top hammer drilling.

How do the top hammer drilling tools perform rock drilling?

Litian top hammer rock drilling tool needs to be installed with the hydraulic rock drill on the rock drilling equipment for rock drilling. The rock drill works according to the principle of impact crushing. When the rock drill is working, the piston makes a high-frequency reciprocating motion, continuously hitting the shank adapter to produce impact energy, which is then transmitted to the drill rod, drill bit, and rock to achieve rock breaking.

What are the reasons that affect the service life of top hammer rock drilling tools?

①Raw material and technology

High-quality raw materials and advanced processing technology can guarantee the overall drilling quality of the rock drill tools from the source and prolong its service life. Choose qualified rock drilling tools and rock drill accessoriesfrom large standardized manufacturers.

② Whether the rock drill tools assembly are concentric

When drilling rock, the shank adapter, the drill rod, and the couplings should be in concentricity. The misalignment of the three will cause bending and deformation of the top hammer drill tools, resulting in stress, resulting in the joint can not cooperate effectively, and causing looseness.

③ Improper use of rock drill tools

When connecting the, it is easy to damage the rock drilling tools chinaif there are mud and sand on the thread, or if there is no lubricating oil at the threaded connection. The combination using of the used drilling rig tool and the new drilling rig tool will shorten the service life of the drilling tool. In addition, the empty beating of rock drill tools should be avoided as far as possible.

④ Propulsion pressure and impact pressure

The propulsion pressure and impact pressure should be set within the rated pressure range.

If the propulsion pressure is too low, it will reduce the drilling penetration efficiency, cause the drilling tool assembly to loosen, and the transmitted energy will be lost, which will cause great stress and cause the instantaneous contact and separation of the contact and joint end faces. If the pressure is too high, the rotation speed of the drill bit is low, there is a danger of sticking, and the bending stress of the drill rod increases.

Improper adjustment of the impact pressure will directly affect the rotation speed and drilling efficiency, and will also affect the life of the drilling tool.

⑤ Rotation speed and rotation pressure.

The rotation speed should match the drill bit diameter and the impact frequency of the top hammer rods, top hammer bits. The cemented carbide of the drill bit has to be rotated at an appropriate angle after each impact, so that new rocks are broken each time.

The normal rotary pressure can provide proper anti-sticking protection for the drill rod. The increment of rotary pressure is the key factor to maintain the tightness of the rock drill tools. if the tightness is not enough, it often causes heating of the joint, peeling off of the thread surface, early wear and even fracture of the thread.
