And top hammer impact drilling mining DTH bit, DTH type impact drilling tool is a kind of compressed air as power source, the dynamics, a large aperture into the rock hole drilling of drill for drilling and blasting method construction machinery, at present in domestic and international application is relatively common in drilling engineering. DTH type impact drilling tool are usually made of drill bit, impact machine, drill pipe of three parts, and equipment in jumbo drill (frame), drilling unit is equipped with air compressor. According to the DTH type impact drilling drilling tools used by different compressed air pressure, usually divided into low pressure DTH drilling tools (0.6 0.8 Mpa pressure), high air pressure DTH drilling tools (1.0 2.0 Mpa pressure), high air pressure Tapered Rock Bit DTH drilling tools (air pressure is greater than 2.5 Mpa) three types.
Due to a difference in the pressure of the drive, the drilling efficiency of DTH drilling tools are different, the performance requirements of the product is different also, therefore, the low pressure DTH drilling tools and high air pressure DTH drilling tools product prices also has bigger difference. At present, the high air pressure DTH drilling tool is in open-pit and underground mining, quarry, water and electricity engineering, water well drilling and digging, mineral exploration, rock cable anchor hole drilling, geothermal, subway engineering digging pile supporting a large aperture is widely used in construction site, such as drilling tools products. The high air pressure DTH drilling drilling tools with drilling rate faster, high hole straightness, hole wall is smooth, good rigidity and a series of drill pipe and percussion tools features by drilling and paid attention to by the construction unit. At present in domestic drilling in the drilling engineering construction site of 110-178 - mm hole, high air pressure DTH drill rock drill is a kind of use large drilling tools.
High air pressure DTH drilling tools products in the material, machining, heat treatment process, as well as the products is very strict in such aspects as overall coordination with the performance. At present, the domestic high air-pressure DTH drill is in product performance and quality of the product development phase, with the domestic high air-pressure DTH drill technical performance index of the stability of product quality and continuously improve, high air pressure DTH drilling tools products will be in the domestic and foreign markets have a bigger market development space. DTH drill bits for mining in its use of time really is very good? This is to make a lot of people are very concerned about a topic, especially for mining DTH drill will often use people, but also very attention. Then mining drill bit the following on this topic for everyone to do a simple introduction, hope to be able to dig DTH bit for everyone to use. For mining DTH drill, just as its name implies is to drill head engraved with the shape of a cross, suitable for for the use of some occasions, and people because it has such characteristics, which will be used very widely. Want to know for mining DTH drill, is absolutely very good, even on either a side, also can be used. For mining DTH bit, of course, also can be divided into a variety of different types and different specifications and models, which requires everyone in its use of time, to the type and model of DTH drill bits for mining know something is possible, because only to know it, so can be more flexible to use. When all of us in the use of DTH drill bits for mining, as long as it is to grasp the accurate, so it must be good.
