  • 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

  • Understanding Chlorine and Trichloroisocyanuric Acid (TCCA)


  • One of the most notorious synthetic preservatives is sodium nitrite, commonly used in cured meats. Sodium nitrite helps prevent bacterial growth and enhances the pink color of meats. However, when exposed to high heat, it can form nitrosamines, which are known carcinogens. Studies have linked high consumption of processed meats containing sodium nitrite to an increased risk of colorectal cancer. The World Health Organization has classified processed meats as a Group 1 carcinogen, indicating sufficient evidence that they can cause cancer in humans.


  • Sodium acid pyrophosphate is also used in the preservation of color and freshness, especially in cut potatoes and other vegetables. Its ability to act as an antioxidant helps to prevent enzymatic browning, thus maintaining an appealing appearance and flavor.


  • Sulfur fertilizers are vital in ensuring optimal plant growth and maximizing agricultural productivity. As we face challenges such as soil degradation and changing climate conditions, the strategic application of sulfur fertilizers can play a significant role in sustainable farming practices, ensuring food security for the growing global population. Increased awareness and understanding of sulfur's importance in agriculture will pave the way for healthier crops and more resilient farming systems.

  • Once the hydrolysis is complete, the sugars are subjected to fermentation, which is the heart of the MSG manufacturing process. A selected strain of bacteria, typically *Corynebacterium glutamicum*, is introduced to the sugar solution. This specific bacterium is non-pathogenic and renowned for its ability to convert sugars into amino acids, particularly glutamic acid. Under optimal conditions, including temperature and pH control, the bacteria metabolize the sugars and produce glutamic acid as a byproduct.


  • Another important aspect of mining chemicals is their role in stabilizing waste materials. Tailings, which are the residual materials left after ore extraction, can pose significant environmental hazards if not managed properly. Chemical agents can be employed to stabilize tailings, minimizing the leaching of harmful substances into the environment. For instance, adding lime to tailings can neutralize acidity, while binding agents can help solidify the materials, preventing airborne dust and contamination of water sources.


  • E322 is a phospholipid that acts as an emulsifier, surfactant, and stabilizer. Lecithin consists of a mixture of fatty acids, glycerol, and phosphoric acid, which allows it to interact effectively with both hydrophilic (water-loving) and hydrophobic (water-repelling) substances. This unique structure makes E322 an effective agent for creating stable emulsions. In food production, it helps to ensure that ingredients such as oil, water, and other components blend seamlessly to maintain consistent texture and appearance.


  • Taste enhancers are substances that amplify the flavors of food, making dishes more palatable and enjoyable. They can be natural or artificial, and their primary function is to enhance the basic tastes. Common examples of natural taste enhancers include salt, sugar, herbs, and spices. On the other hand, artificial taste enhancers, such as monosodium glutamate (MSG), have sparked considerable debate regarding their safety and impact on health.
