The 20mm drill rod finds a wide range of applications across different sectors. In the geological and mining industries, these rods are used for exploratory drilling and core sampling. Drillers can obtain valuable subsurface samples, allowing geologists to analyze mineral composition and assess potential mining projects. The precise and efficient nature of the 20mm drill rod enhances the accuracy of these assessments, ultimately leading to better-informed decisions.

  • 4. The average flow rate of the pipeline is too low, and the average flow rate of the pipeline is lower than the critical settlement deceleration, resulting in pipeline blockage and unable to transport slurry normally. Through the above examples, it can be seen that the selection of ZJ series slurry pump is more complicated, and if any link makes a mistake, it may lead to the mistake of the entire selection, causing irreparable losses to users, and having an adverse impact on their reputation. Therefore, in the selection, we must pay attention to the values of several key coefficients and calculate them carefully to achieve accuracy, so that the ZJ series slurry pump can fully reflect its advantages in field application.

  • 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
