  • 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

  • Butyl rubber, also known as isobutylene-isoprene rubber (IIR), is a polymer made primarily from the polymerization of isobutylene with a small amount of isoprene. This combination results in a rubber that possesses exceptional impermeability to gases, making it particularly useful in applications where air retention is crucial. Its unique structure gives it a high degree of elasticity and resilience, which further enhances its usability in various products.


  • While E211 is considered safe in moderation, some individuals may be sensitive to sodium benzoate and experience allergic reactions, including skin irritations and respiratory issues. Moreover, ongoing debates about the long-term health effects of consuming preservatives have led some consumers to gravitate towards natural alternatives.


  • One of the principal functions of sodium citrate in food is to act as an acidity regulator. It helps stabilize pH levels in various products, ensuring that flavors remain consistent and preventing spoilage caused by microorganisms. Sodium citrate is commonly found in processed cheeses, where it helps maintain a smooth texture by preventing fats from separating and contributing to a uniform melt.


  • One of the lesser-known aspects of MSG is its potential role as a preservative. Although it primarily serves to enhance flavor, its ability to inhibit the growth of certain bacteria hints at its preservative qualities. Preservatives are substances added to food products to prevent spoilage caused by microorganisms. While traditional preservatives like sodium nitrite and sorbates have been used for years, MSG offers an alternative, especially in enhancing the taste of preserved foods.

  • As with any synthetic material, the environmental impact of butyl rubber is a topic of interest. While butyl rubber is not biodegradable, its long lifespan and durability contribute to reduced waste generation. Moreover, advances in recycling technologies are improving the sustainability of synthetic rubbers, including butyl rubber, leading to innovative solutions that minimize environmental footprints.
