  • 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

  • The Role of Sodium Bicarbonate Properties, Uses, and Benefits


  • E477 is derived from glycerol, a naturally occurring compound found in fats and oils. It is produced through the process of esterification, where glycerol reacts with fatty acids. This process creates a versatile compound that can interact with both hydrophilic (water-loving) and hydrophobic (fat-loving) substances, allowing it to effectively stabilize emulsions. The unique properties of E477 enable it to function as an emulsifier, thickener, and stabilizer in various formulations.

  • Citric acid is generally recognized as safe (GRAS) by major food safety authorities, including the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). It is deemed safe for consumption in moderate amounts, commonly found in various food items ranging from dressings to confectionery.

  • Regulatory bodies have placed limits on the amount of E281 that can be used in food products to ensure consumer safety. These regulations are based on extensive scientific research that evaluates the potential effects of food additives on human health. E281 is generally recognized as safe when used within predetermined limits, and adverse effects are rare. However, sensitivity to food additives varies among individuals, and some may experience intolerances or allergic reactions.


  • Given its varying compositions, businesses in the wholesale market must carefully choose which type of denatured alcohol to stock based on their customer needs and regulatory guidelines.


  • In food manufacturing, carrageenan is predominantly used for its thickening and gelling abilities. It belongs to a category of thickeners known as hydrocolloids, which have the unique ability to form a gel when mixed with water. Depending on the source and processing method, carrageenan can take on different forms, including kappa, iota, and lambda, each serving distinct functions in food applications.

  • Xanthan gum functions as an emulsifier primarily due to its unique molecular structure, which is characterized by a high molecular weight and the ability to form a gel-like consistency in solution. When xanthan gum is added to a mixture of oil and water, its molecules interact with both phases, allowing it to stabilize the emulsion. This stabilization primarily occurs through two mechanisms


  • Despite their numerous advantages, the use of gums as food additives is not without controversy. Some consumers are wary of food additives in general, associating them with processed foods. As a result, transparency in labeling and sourcing is essential for manufacturers. There is a growing trend towards clean-label products, which means that consumers prefer foods with simple, recognizable ingredients. In response to this demand, many companies are now highlighting the natural origins of gum-based additives in their marketing efforts.

  • Carob bean gum is a natural thickening and gelling agent, primarily composed of galactomannan, a type of polysaccharide. The extraction process involves crushing the seeds of the carob pods and separating the gum from the fibrous material. The resulting powder is odorless, tasteless, and has a light brown color, making it an ideal ingredient for various food formulations.

  • Potassium sorbate is used to inhibit molds and yeasts in many foods, such as cheese, wine, yogurt, dried meats, apple cider, dehydrated fruits, soft drinks and fruit drinks, and baked goods.[8] It can also be found in the ingredients list of many dried fruit products. In addition, herbal dietary supplement products generally contain potassium sorbate, which acts to prevent mold and microbes and to increase shelf life. It is used in quantities at which no adverse health effects are known, over short periods of time.[9] Labeling of this preservative on ingredient statements reads as potassium sorbate or E202. Also, it is used in many personal-care products to inhibit the development of microorganisms for shelf stability. Some manufacturers are using this preservative as a replacement for parabens. Tube feeding of potassium sorbate reduces the gastric burden of pathogenic bacteria.

  • 2. Energy Costs The production of aluminum hydroxide is energy-intensive. As energy prices rise, manufacturers may pass on these costs to consumers, leading to increased prices for aluminum hydroxide.


  • In swimming pools, maintaining proper chlorine levels is vital to ensure the safety of swimmers and the longevity of pool equipment. TCCA 90% is often used for routine disinfection due to its ability to provide a continuous sanitization effect. It can be added to pool water in granular form or through a floating dispenser, allowing for easy incorporation into existing maintenance routines. Furthermore, TCCA has a low solubility and a slow dissolution rate, which means that chlorine levels can be maintained consistently without the risk of spikes that could harm swimmers or damage pool infrastructure.
