D miningwell Dth Hammer Rock Drilling Tool
D Miningwell DTH hammer works efficiently at the same time, reliability and long life are the advantages of our products. Among all industrial equipment, DTH hammer and drill have the worst working environment, and the working process is uncontrollable and unpredictable. D Miningwell DTH hammer has high matching precision of its internal parts. D Miningwell guarantees the material and processing quality of each part of DTH hammer, and good lubrication conditions can significantly improve the efficiency, stability and life of DTH hammer.
The down-the-hole hammer cooperates with the down-the-hole drilling rig and the dth drill bit, and is mainly used in the construction of mining, marble quarry blasting hole drilling, water well drilling engineering or drilling and other engineering construction.
1. The drill bit does not require nylon tubes, thus eliminating the trouble of nylon tubes being broken, damaged and hard due to thermal expansion and contraction.
2. DTH hammer without nylon tube has low energy consumption, high impact frequency, and the drilling speed is 15%-30% faster than the same type of DTH hammer with nylon tube.
3. Because the structure is very simple and the components are reliable, DTH hammer is easy to maintain and has a longer service life.
