  • 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

  • Rubber splicing tape is a specialized tool used in the process of joining two ends of rubber conveyor belts. This process, known as splicing, is crucial for ensuring the continuity and efficiency of material handling systems that rely on conveyors. The tape serves as a bonding medium that connects the two belt sections together, forming a seamless transition between them.

  • In the industrial landscape, control boxes are the linchpins of efficiency and safety. Here’s how:

  • Moreover, this tape is frequently employed in the construction and repair of motors, generators, and transformers. It provides a temporary or permanent solution to insulate windings and other components that operate under high tension. The tape's adhesive backing ensures a secure fit, while its heat resistance allows it to function effectively even in hot operating conditions The tape's adhesive backing ensures a secure fit, while its heat resistance allows it to function effectively even in hot operating conditions The tape's adhesive backing ensures a secure fit, while its heat resistance allows it to function effectively even in hot operating conditions The tape's adhesive backing ensures a secure fit, while its heat resistance allows it to function effectively even in hot operating conditionshigh voltage rubber tape.
  • 5. Sika With a focus on construction and automotive industries, Sika offers a range of butyl tapes for waterproofing, bonding, and sealing applications. Their products are backed by strong technical support and innovative research.
  • Moreover, automotive fabric tapes are known for their durability and resistance to harsh environmental conditions
  • The key feature of self-bonding rubber tape lies in its self-adhesive property. When pressure is applied, the tape's surface layers adhere to each other, creating a strong, air-tight seal. This characteristic makes it ideal for applications where conventional tapes might fail, such as in wet or humid conditions, or in environments with extreme temperatures. The tape's rubber composition also imparts excellent elasticity, allowing it to conform to irregular surfaces and maintain its integrity under stress.
  • Vulcanizing tape is a specialized type of tape that is commonly used in the automotive and plumbing industries for repairing hoses, pipes, and other rubber materials. It is also known as self-fusing or self-amalgamating tape because it fuses to itself when stretched and wrapped around an object. This unique property makes vulcanizing tape incredibly versatile and effective for a wide range of applications.
  • Another key benefit of EPR self-amalgamating tape is its ease of use. Unlike traditional tapes that require adhesive or heat to bond, this tape simply needs to be stretched and wrapped around itself to create a secure seal. This makes it a quick and reliable solution for emergency repairs or on-site installations.
  • Butyl rubber tape is also known for its flexibility and easy application. It can be easily cut to size and molded to fit the shape of the surface being sealed. This flexibility allows for quick and efficient repairs without the need for specialized tools or equipment
