Products Description In air-circulation drilling, if a formation is too hard for penetration by a drag bit, a DTH hammer is generally employed. This tool was developed for the mining and quarrying industry. The ‘business’ end – the button bit – is studded with hemispherical tungsten carbide ‘buttons,’ and with channels built in to allow the passage of compressed air. When the hammer is pressed against the ground, the bit is forced into a pneumatic hammer action (like a road drill) by compressed air fed down the drill pipes. Then, as the tool is rotated in the hole, the buttons act across the entire base of the borehole. Most hammers rotate at speeds of 20 to 30 revolutions per minute, and blows can be struck at rates of up to 4000 per minute. Debris is normally flushed (blown) out of the hole at the end of each drill pipe. DTH hammers are most effective in hard rock formations such as limestones or basalts; soft, fine-grained formations tend to clog the air ducts or jam the piston slides. Nonetheless, DTH hammers are extremely cost-effective and hence very popular with commercial drillers. Test Deepth of DTH Drilling Hammers Rock formation Drilling meters Granite 16400 ft above Abrasive granite 9800 ft above Sandstone 26300 ft above Advantages: Our DTH hammer and bits has following advantages: Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to inner structure of DTH hammer designed according to newest rock drilling theory. Smooth performance and long service life of DTH hammer due to high quality alloy steel materials and advanced processing technology adapted. Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of hammer. Easy to depart bit from hammer due to multi-head thread connecting chuck and cylinder of hammer. Interchangeable with DTH bit and dill pipe manufactured by many brands all over the world.顯示更多
