  • 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

  • The term “wrought iron” often gets misused today to refer to any metalwork – often mild steel or cast iron – that’s designed to have the precise, intricate appearance of the classical wrought iron designs from the nineteenth century. However, to truly be wrought iron, the metal has to have been forged, heated, and hammered by a trained blacksmith, a process that’s become much rarer today than it was in the past. The hand craftsmanship that goes into its design and construction makes wrought iron a truly unique and special material today.

  • Cast iron, however, is generally more cost efficient and less labor intensive than wrought iron because it doesn’t need to be worked by hand. Since the iron is shaped by pouring it into molds, cast iron is often used to create very intricate designs or to recreate historical or period-specific patterns very precisely.

  • The origins of head spearing can be traced back to prehistoric times when tribes engaged in territorial disputes and battles for survival. In some indigenous societies, such as the Igorot people of the Philippines or the Dayak tribes of Borneo, headhunting was seen as a rite of passage, a symbol of bravery, and a way to bring honor to one's clan. The act of taking an enemy's head was believed to harness their strength and spirit, empowering the victor and his community.


  • One of the most frequent questions I get as a fence designer is whether to install either a wrought iron or aluminum fence.  Both are great fencing materials and both will do the job of providing a highly secure perimeter for your home or commercial property.  However, there are some distinct differences between the two fence materials worth considering before making a final decision. I hope that this explanation of their differences will help!

  • The drawbacks of iron fences are that they are often difficult to install, and the materials are very expensive.

  • Pricing is often a significant consideration for buyers; however, it should not be the only factor influencing your decision. While finding a competitively priced supplier is important, it should not come at the cost of quality. Low prices may indicate inferior materials or cut corners in production, resulting in subpar products. Therefore, it’s essential to strike a balance between cost and quality when selecting a wrought iron supplier.

Once installed, it is virtually impossible for anyone to access your keys without your permission.
  • Aluminum, as a material, is renowned for its lightweight yet robust nature. Its high strength-to-weight ratio makes it ideal for window frame extrusions. The process of extrusion allows manufacturers to shape aluminum into intricate profiles, meeting diverse architectural designs and specifications. The frames are formed by forcing aluminum through a die under high pressure, creating a consistent and precise cross-sectional shape, tailored to the needs of each window.

  • First and foremost, quality is paramount when it comes to wrought iron products. A reliable supplier should provide materials that meet industry standards for strength and durability. Low-quality wrought iron can lead to safety issues, especially in structural applications. Buyers should look for suppliers who can demonstrate compliance with relevant standards or certifications. Additionally, customers should ask about the supplier's production processes and whether they employ quality control measures to ensure that the finished products are free from defects.

  • A wrought iron fence is not complete without a gate. Gates provide access and enhance the functionality of the fence while maintaining security. Wrought iron gates come in various designs, from simple swing gates to more ornate models with intricate scrollwork. They can be operated manually or installed with automatic openers for added convenience. The gate hardware, including hinges and locks, is equally important as it must be robust enough to withstand daily use.


  • Before installing the new rollers, it's a good idea to clean the track and frame of any dirt or debris to ensure smooth operation. You can use a brush or vacuum to clean out any buildup in the track. Once the track is clean, you can insert the new rollers into the frame and secure them with the screws

  • The Enigma of the Metal Box with a Key Lock
  • Furthermore, aluminium is an excellent conductor of heat, which can be advantageous in window systems. Thermal break technology, often incorporated in aluminium profiles, creates a barrier between the inside and outside of the frame, reducing heat transfer. This improves insulation, leading to energy savings and enhanced comfort levels within the building.

  • 4. Adjustment Sometimes, the alignment of the rollers may need adjustment. If a window is difficult to open or closes unevenly, consult a professional to make the necessary adjustments.
