Rig: by crushing rock ore body of work, divided into rope impact drill, drill hole, rotary drill and rotary drill. Rope impact rig due to low efficiency, has gradually been replaced by other rig. DTH drill rig driven by pneumatic impactor and bit rotate together, the impact of the use of pneumatic piston shock fracture rock drill, usually used in small and medium mine blast hole drilling diameter of 80 to 250 mm. Rotary drill to fracture rock action by rolling cone bits, suitable for drilling in hard rock and minerals diameter of 150 to 440 mm bore, it has high efficiency, low labor intensity of merit obtained in the medium and large open-air metal ores widely used. DTH (or cone) rig by impactor (or drill), Rotary, lifting mechanism, pressure equipment, travel agencies, slag systems, drill rigs and components. Rotary drilling rig is only suitable for softer rock and coal mines. Sale of second-hand air compressor, used drilling rigs, leasing, recycling business, contract various DTH drilling drilling project! Kisan Compressor Rental Co., Ltd. Shanxi submersible drilling rig in the use of the process, sometimes "run drill" phenomenon. Today, Shanxi Qishan Compressor Rental Co., Ltd. to share with you how to solve the "running drill" phenomenon? Submersible drilling rig because of its relatively simple dynamic open-air DTH crawler drill, the structure is simpler and more use of the characteristics, it is suitable for more complex terrain venues operations. Submersible drilling rig when in use if there is a "run drill" phenomenon, then this how to solve it? But to solve the problem must first understand the reasons arise. Because an impact drill head assembly of large diameter than the open-air DTH drill drill rod, and the length is longer distance open-air DTH drill manufacturers, drill bits and help solder between relatively distant second-hand open hole drilling Moreover drill rod has a certain degree of flexibility, so the irregular cut jobs when the rock is very prone to "run the drill" phenomenon is rock hole axis deviation rig. In this case, it is easy if you have to continue drilling will cause the drill rod bending, or even "Do not drill" phenomenon, resulting in the rig does not work, and the situation on the submersible drilling rig itself can also cause serious damage to make this issue resolved, you can use a solder bucket support locator installed in front of the two legs of the rig. Practice has proved that good results positioning, positioning can be a good solution, "ran the drill" phenomenon.
