  • 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

  • HPMC is a non-ionic, water-soluble compound derived from natural cellulose. Its unique chemical structure incorporates hydroxypropyl and methyl groups, which enhance its solubility and thermal stability. HPMC powders exhibit high viscosity, excellent gel-forming capabilities, and improved adhesion properties. These characteristics make HPMC an ideal additive for many formulations, providing both thickening and binding functionalities.


  • HPMC grades are categorized based on their viscosity, typically measured in centipoise (cP) at a specific concentration and temperature. Common grades include

  • Furthermore, HPMC 200000 is non-toxic, odorless, and easily dispersible in water, making it safe and convenient to use in various applications. It is also compatible with a wide range of other ingredients and materials, which allows for easy formulation and customization of products. Its versatility and ease of use make HPMC 200000 a popular choice among formulators and manufacturers.
  • Toxicological studies indicate that HPMC does not exhibit carcinogenic, mutagenic, or reproductive toxicity. Furthermore, it is not absorbed in significant quantities by the gastrointestinal tract, which minimizes systemic exposure. As a result, HPMC is suitable for use in products that require ingestion, such as pharmaceuticals and food.


  • In the pharmaceutical industry, specific grades of HPMC are often preferred for drug formulation. For instance, lower viscosity grades are commonly used in tablet manufacturing as binders and disintegrants. These grades help to control the release of active pharmaceutical ingredients (APIs) while ensuring that the tablets are easy to form. Conversely, higher viscosity grades are often used in controlled-release formulations due to their ability to form gels when in contact with water, thus providing a sustained release of the drug.

  • Conclusion


  • - Versatility HEC’s multifunctional properties allow it to be used across diverse industries. Whether in cosmetics, pharmaceuticals, or construction, its adaptability makes it invaluable.


  • In contrast, HEC is produced by etherifying cellulose with ethylene oxide. While HEC also displays good solubility in water, its viscosity and thickening properties can be influenced by temperature changes and pH levels. HEC tends to exhibit higher viscosity formulations at lower concentrations compared to HPMC, which might be advantageous in certain applications.


  • HPMC is also a popular ingredient in the cosmetics and personal care industry. Its thickening and stabilizing properties make it an excellent choice for formulating lotions, creams, shampoos, and conditioners. HPMC enhances the viscosity of these products, allowing for a more pleasant application experience. Additionally, its film-forming properties contribute to long-lasting effects in products such as sunscreens and makeup formulations.
