1. Dented, chipped, or damaged striking endProbable causes:- Misalignment from worn out bushings- Piston damageSuggested actions:- Replace worn out components in rock drill, including but not li
1. Dented, chipped, or damaged striking endProbable causes:- Beginning percussion or rotation with the shank end placed against the coupling’s shoulder- Feed misaligned- Misalignment from hole deviati
1. Failure Across Female ThreadsProbable causes:-Hole deviation or drill string misalignment-Insufficient feed pressure-Excessive torque due to use of worn drill bits-Mismatched threads-Dents or defor
1. Body WashProbable causes:- Drilling under extremely abrasive conditions- Overwhelming flushing volumeSuggested actions:- Reduce flushing volume- Slow drill rotation to create larger cuttings for mo
DTH drill rods are essential tools in drilling operations, and are widely used mining, geotechnical engineering, hydraulic construction, and geological exploration. 1. Functions of DTH Drill Rods
Friction welding originated over a century ago and after more than half a century of research and development, friction welding technology matured and entered the stage of widespread application. Sinc
Anchor drill rigs are essential machinery for implementing anchor bolt support technology. With the rapid development of anchor bolt support technology, anchor drill rigs have also developed quickly.
Anchoring technology is a method of fixing one end of a tensile rod in the rock or soil layer of a slope or foundation, and connecting the other end to the structural building to withstand thrusts imp
DTH hammers designed for DTH bits with foot vavle V.S DTH hammers designed for DTH bits without foot valve DTH drill bits and hammers use compressed air to generate impact energy, dri
It’s been nearly a century since the invention of DTH hammer. It was originally used for drilling and blasting in quarrying and surface mining.1. Birth of DTH HammersIn 1857, Italian engineer Bartritt
Low pressure, medium pressure or high pressure DTH hammers?Air pressure is the power source for DTH hammers during operation, directly determining their efficiency and drilling speed. Based on the wor
DTH button bits are widely used in mining, quarrying, water conservancy engineering, water wells, railway, and highway construction due to their high efficiency, safety, environmental protection, simp
Tapered drill rods are driven by small pneumatic or hydraulic rock drills, in conjunction with tapered drill bits, to perform shallow drilling operations. They are commonly used in industries such as
