  • 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

Additionally, HEC can be used as a film-forming agent in the production of oral films and coatings for tablets.
  • In summary, Hydroxypropyl Methylcellulose (HPMC) embodies versatility across multiple industries due to its unique chemical properties and modifications. Its applications in pharmaceuticals, food, and construction demonstrate its significance as a functional ingredient. As the industries continue to evolve, the demand for high-performance materials like HPMC is likely to grow, further establishing its importance in contemporary manufacturing and formulation processes. Its non-toxic nature and adaptability make HPMC a vital component, contributing to innovations and advancements across various fields. As we move forward, understanding and utilizing HPMC's properties will remain essential for creating effective, safe, and sustainable products.


  • In personal care products, HPMC is used in various formulations, including cosmetics, lotions, and shampoos. Its thickening and emulsifying properties help create stable formulations while enhancing the sensory experience of the final product. HPMC is often found in products designed for sensitive skin due to its hypoallergenic nature, making it suitable for a wider audience.


  • In the food industry, hydroxypropyl methylcellulose is recognized for its ability to act as a thickener, stabilizer, and emulsifier. It contributes to the texture of numerous products, including sauces, dressings, dairy items, and baked goods. By improving the consistency of food items, HPMC enhances consumer satisfaction with sensory attributes.


  • In the construction sector, HPMC is employed as an additive in cement mortars, plasters, and tile adhesives. The cold water solubility of HPMC ensures that it can be easily mixed with water, allowing for improved workability and adhesion properties in construction materials.


  • To prepare HPMC gel, one must first dissolve HPMC powder in water. This can be done by adding the powder slowly to water, while stirring continuously to prevent clumping. The mixture is then allowed to hydrate and swell for a period of time, typically a few hours, until a gel-like consistency is achieved. This process is known as the gel hydration process.
