  • 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

  • So, Should You Go With an Aluminum Fence vs Wrought Iron Fence?

  • Repaint Your Fence
    Before you start painting, it might be a good idea to add a primer to your fence. Make sure you’re buying a primer that’s specifically made for metal, as these can be purchased with rust inhibiting qualities. Once you’ve applied your primer, choose your paint colour and use a small paint brush to cover all areas of your fence with a thin coat of paint. Allow the paint to dry fully before applying a second coat. We recommend a paint such as hammerite to re-coat paintwork when necessary.

  • Hiking also offers a wide range of physical and mental health benefits. Not only does it provide a great cardiovascular workout, but it also helps to reduce stress, improve mood, and boost overall well-being. Spending time in nature has been shown to lower blood pressure, decrease anxiety and depression, and enhance cognitive function.
  • Now, use your socket wrench or crescent wrench to turn the wheel assembly until it is adjusted to the correct height. The goal is to have the wheel centered in the track, with equal distance on either side. If the wheel is too high or too low, it can cause the door to bind or come off the track altogether.
  • Another great benefit of using a fly screen door roller is that it enhances the overall appearance of your home
  • In the medical field, Polymeric New Type materials are being used to create advanced medical devices and implants that are more biocompatible and less likely to cause adverse reactions in patients. For example, polymer-based stents and prosthetics are more flexible and less invasive than traditional metal alternatives, leading to faster recovery times and better outcomes for patients.
  • However, it's crucial to understand that the performance of a sliding door largely depends on the quality of its roller assembly. A poorly designed or worn-out assembly can result in sticking, noise, and premature failure. Regular inspection and timely replacement of worn parts are essential to maintain optimal performance.

  • Stainless steel finger pulls are versatile and can be used in a variety of applications. From kitchen cabinets to sliding barn doors, from closet systems to office partitions, these pulls can adapt to different settings with ease. Their low-profile design allows them to be installed on various thicknesses of doors, making them suitable for both residential renovations and new commercial constructions. Additionally, they can be found in various shapes and sizes, enabling designers to choose the perfect fit for their projects.


  • High humidity, saltwater, and constant exposure to rain can accelerate rust formation on wrought iron. On the other hand, in drier climates or indoor environments, rusting may occur at a much slower pace. Regular maintenance and care play a crucial role in preventing or slowing down this process Regular maintenance and care play a crucial role in preventing or slowing down this process Regular maintenance and care play a crucial role in preventing or slowing down this process Regular maintenance and care play a crucial role in preventing or slowing down this processwill wrought iron rust.
  • One key feature of aluminum window extrusion profiles is their thermal efficiency.
