  • 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

  • Hydroxypropyl methyl cellulose, commonly abbreviated as HPMC, is a versatile pharmaceutical excipient widely used in the formulation of various dosage forms. This semi-synthetic polymer is derived from naturally occurring cellulose, which is modified through the addition of methoxy and hydroxypropyl groups to improve its solubility and stability in water. The resulting compound possesses unique characteristics that make it an indispensable component in the manufacturing process of tablets, capsules, films, and even some types of suspensions and emulsions. One of the primary functions of HPMC is as a binder in the production of tablets. It provides cohesion between particles, ensuring that the tablet maintains its structure during compression and post-production handling. Moreover, HPMC can act as a release-controlling agent due to its ability to form a gel layer upon contact with aqueous fluids. This property allows for the sustained or controlled release of active pharmaceutical ingredients (APIs), which can optimize therapeutic efficacy by maintaining drug levels within the desired therapeutic window over an extended period. In addition to its role in solid dosage forms, HPMC also finds application in the preparation of film coatings. These coatings protect the core tablet or capsule from environmental factors such as moisture and light while improving the aesthetic appeal and patient acceptability of the medication. Furthermore, the use of HPMC in film coatings can facilitate the development of modified-release dosage forms, where the rate at which the API is released into the body is carefully managed to suit the treatment regimen. Another notable advantage of using HPMC is its non-toxicity and biocompatibility Another notable advantage of using HPMC is its non-toxicity and biocompatibility
