Coal Briquetting Binder - the Best Partner to Improve Pulverized Coal Molding
As the degree of coalification increases, the plasticity of coal decreases rapidly, and the formability resistance changes. For coal with a high degree of coalification, it is generally necessary to add a viscous agent to increase the plasticity of the coal before it can be formed.1. Shape characteristics of coalThe forming characteristics of coal is an important internal reason affecting the forming process of coal powder, especially the elasticity and plasticity of coal are more prominent. The plasticity of coal is higher and higher, and the formation of coal dust is more typical.2. Molding pressureWhen the forming force is less than the pressure crushing force, the mechanical strength of the formed coal increases with the increase of the forming pressure. Different types of coal have different crushing forces. The pressure is closely related to the type of coal, the combination of moisture and particle size of the material, the type and quantity of the binder, etc.3. Material moistuRead more -
Binder for Briquettes of Phosphorus Ore Powder, Saving Cost and Improving the Utilization Rate of Phosphorous Powder
Phosphorous powder, gray or brown, has no smell. The main component is fluorapatite (chemical formula, Ca10(PO4)6F2), containing 10-35% of total phosphorus (phosphorus pentoxide), of which 3-5% phosphorus is soluble in weak acid and can be absorbed and utilized by crops. Other large Some crops are difficult to absorb and utilize directly, and belong to insoluble phosphate fertilizers.In recent years, there has been a shortage of phosphate rock resources. The output of phosphorous powder brought by phosphate rock mining is large, and the excess phosphorous powder will take up a lot of space. Therefore, many companies have begun to try to shape phosphorous powder to smelt yellow phosphorus, which can also replace part of the phosphate rock. According to the requirements of customers in the phosphate rock market, Jianjie Group has developed a phosphorous powder binder suitable for phosphorous powder molding. This product has good molding effects, less additives, and low production costs.Read more -
Recycling of Dedusting Ash from Steel Plant
Dedusting ash generally refers to the dust, smoke, sludge and other wastes left by the dedusting of steel plant. For example, during the blast furnace and converter smelting process, there are blast furnace bag ash, ash collected by LT dedusting method, steelmaking dedusting ash, etc. Dedusting ash is rich in Fe, CaO, MgO, C, etc., and some also contain elements such as Zn, K, Na, etc., which has high recycling value, and direct disposal will easily cause resource waste and environmental pollution. At present, dust from steel plant is returned to the furnace for recycling, and cold-pressed pellets are often used for recycling. Zn-rich ash contains a lot of environmental pollutants, which will not only cover a large area and cause environmental pollution problems, but also directly return to sinter production will also cause a decline in the quality of sinter, affecting the smooth running of the blast furnace and the life of the blast furnace. Therefore, in order to make reasonable useRead more -
Development Trend of Iron Ore Pellets Binder
As the demand for sustainable mining practices increases, the development of eco-friendly binding agents for ore pellets has become a major focus for mining companies. The use of traditional binding agents such as bentonite, a type of clay, has been proven to be unsustainable and harmful to the environment. Therefore, there is a need for more sustainable alternatives.One of the most promising developments in this field is the use of biopolymers as binding agents. Biopolymers are natural, renewable materials that are biodegradable and environmentally friendly. They can be derived from a variety of sources such as plant fibers, starches, and proteins.Another potential development is the use of nanotechnology in the production of binding agents. Nanoparticles can improve the strength and durability of pellets, reducing the need for excessive use of binders. Additionally, they can enhance the flow properties of the pellets, improving the efficiency of the production process.The developmentRead more -
Coal Briquette Binder Is Making Waves In The World Of Fuel Manufacturing
Open pit mine, breed sorting. Mining coal. Bulldozer sorts coal. Extractive industry, anthracite. Crushing marshalling complex. Coal industry. Black goldBinder for coal briquette is a new product that is making waves in the world of fuel manufacturing. This specially formulated binder is designed to bind coal dust and other materials together to create high-quality briquettes that burn efficiently and cleanly.Coal briquette binder is made from a blend of high-quality chemicals that react with the coal dust to create a strong, durable bond. This bond not only holds the briquettes together but also helps to improve their combustion properties, resulting in a more efficient and cleaner-burning fuel.One of the key benefits of coal briquette binder is its versatility. It can be used to bind a wide range of materials together, including coal dust, sawdust, and other biomass materials. This makes it an ideal choice for fuel manufacturers looking to create high-quality, eco-friendly briquettesRead more -
India Tata Steel Invests up to $795 Million in Expansion of Capacity of Subsidiary NlNL
Tata Steel Limited, India's leading steel company, announced on March 29th its plans to invest approximately $795 million (equivalent to approximately 5.748 billion RMB) in its subsidiary, Neelachal Ispat Nigam Limited (NINL), for the expansion of its long steel products.NINL, acquired through the Indian government's disinvestment program in early 2022, is a producer of long steel products. Since acquiring this state-owned enterprise, Tata Steel's focus has been on revitalizing the facility and increasing its production capacity to 1.1 million tons per year. The company further stated its intentions to expand NINL's capacity by an additional 4 million tons per year in the next phase, ultimately reaching a production capacity of 5 million tons per year.Additionally, NINL boasts a 62-megawatt captive power plant and reserves of 90 million tons of iron ore. It is strategically located adjacent to another steel plant owned by Tata Steel in India, which is nearing completion of its expansioRead more -
Nucor signs agreement with Samarco for DRI pellet supply
Brazilian iron ore miner Samarco and North American steelmaker Nucor have signed a new five-year commercial agreement for the supply of iron ore direct reduction pellets.Nucor is the largest steel producer in the United States and the largest recycler of scrap in North America.According to Rodrigo Vilela, Samarco’s chief executive officer, the demand for pellets, especially direct reduction pellets, is on an upward trajectory driven by the decarbonization path as industries are increasingly turning to cleaner alternatives that emit fewer greenhouse gases during production.“The initiatives and actions taken to reduce CO2 emissions are a global reality, and Samarco has all the attributes to become a strategic supplier in terms of decarbonization and will accomplish this through joint developments with strategic customers such as Nucor. Samarco is also working to meet all such established goals until 2050.”Vilela also said that this new long-term agreement with Nucor comes in line with thRead more
