  • 3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm. The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal. The common feature of these devices is that the degree of automation is getting higher and higher, and some functions realize the application of intelligent i GPS technology on these RIGS, which realizes the automatic positioning of the boom, saves the time of field marking and positioning, improves the efficiency of the operation, and enables the operator to concentrate on monitoring the process of drilling. At the same time, more attention is paid to safety and environmental protection and the improvement of human-machine relationship. With the impact of the implementation of engine emission regulations, mobility, intelligent handling and environmental regulations Tier 3/ Euro ⅢA emission regulations, most foreign rig manufacturing companies have adopted diesel engines that meet the emission standards

  • Furthermore, portable drills are available in a range of sizes and power levels, allowing you to choose the model that best suits your needs. From compact drills that are perfect for light-duty tasks to more powerful models that can handle heavy-duty construction work, there is a portable drill for every job.
  • two types of fiberglass grating (FRP): FRP Molded Grating and FRP Pultruded Grating.

  • One of the key advantages of the anchor cross bit is its ability to provide increased stability during the drilling process. This is particularly important when drilling through challenging rock formations, where the risk of instability is higher. The cross-shaped design of the bit helps to distribute the weight evenly, reducing the chances of the drill string becoming stuck or deviating off course.

  • To begin the drilling process, it is important to first assess the condition of the limestone. This includes determining its thickness, density, and any potential weaknesses or fractures. Once these factors have been evaluated, a suitable drill bit must be selected. For limestone, diamond-tipped drill bits are typically the most effective option as they can withstand the high temperatures and pressures generated during drilling.
  • In the annals of engineering and construction history, the gasoline-powered rock drill has emerged as a groundbreaking tool, revolutionizing the way we excavate and shape the earth. This mechanical marvel, fueled by gasoline, has been a game-changer in the realms of mining and construction since its inception.
