Optimization of Silo of Vertical Intensive Mixer

Optimization of Silo of Vertical Intensive Mixer

2020-09-18

The mixing of powder materials is very common in industrial production and occupies a very important position in the production process. It is widely used in metallurgy, pharmacy, construction and other aspects. Vertical high intensive mixer is an important equipment in mine material production system. Horizontal mixer has been used for a long time, but its mixing effect is poor and energy consumption is very large. The vertical multi-propeller high intensive mixer being developed lacks design theory and experience, and there are many key technologies to be overcome. According to EDEM discrete element simulation method, the movement process of the mixer bin is simulated, and the rotation parameters of the mixer bin are optimized to improve the mixing effect and service life of the mixer.

Cold Briquette With Chrome Ore Fines

Cold Briquette With Chrome Ore Fines

2020-09-18

At present, the main raw materials for smelting ferrochromium alloy are chromium lump ore and chromium fine ore. Due to the requirement of air permeability of furnace burden in the smelting process, chromium lump ore is usually more suitable for smelting. However, with the large demand for resources in the contemporary ferrochromium alloy industry, there are fewer and fewer chromium ores suitable for direct furnace entry and the price is getting higher and higher. At the same time, with the increase of chromium ore mining and the decrease of crude ore grade, the output of chromium fine ore is getting higher and higher. In smelting, compared with chromium lump ore, chromium fine ore is easy to lead to poor thermal permeability of ore and cannot be directly put into the furnace, but it has better characteristics than chromium lump ore in other aspects, such as high taste and low price.

Chinese Classical Instrument- Guzheng

Chinese Classical Instrument- Guzheng

2020-09-18

Guzheng, also known as Han Zheng, Qin Zheng, Yao Zheng and Luan Zheng, is one of the traditional musical instruments of the Chinese Han nationality and belongs to plucked string instruments. It is one of the unique and important national musical instruments in China. Its timbre is beautiful, its range is wide, its playing skills are rich, and it has quite strong expressive force, so it is deeply loved by the broad masses of the people.

Binder for Coke Powder Cold Briquetting-Sodium Silicate

Binder for Coke Powder Cold Briquetting-Sodium Silicate

Coke is the main fuel in iron-making industry, but coke is fragile and there are a lot of cheap coke powder. However, the high content of coke powder in iron-making fuel will inevitably affect the air permeability in the furnace during iron making, so it is necessary to block coke powder. At present, coke powder can only be made into blocks by agglomeration method, and the key technology is the development of molding binder. Common binders include inorganic binders, such as hydrated lime, Portland cement and bentonite, which only make the green ball strength of coke powder pellets meet the use requirements, but the dry ball strength cannot meet the use requirements. In addition, there are industrial wastes, such as sulfurous acid pulp waste liquid, which contains sulfur, which will cause harm to iron-making and will not be used in general. Pure organic binder, expensive. Sodium silicate is rich in resources and low in price.

Powder Mixing in Planetary Mixer

Powder Mixing in Planetary Mixer

Planetary mixer is a kind of fixed container batch spiral mixer. It relies on the spiral rotation and revolution in the inverted conical container to make the powder in the container undergo three-dimensional convection, shear and diffusion mixing.

Application of high-strength aluminum iron briquette

Application of high-strength aluminum iron briquette

2020-09-08

As one of the main deoxidizers in steelmaking process, Al-Fe alloy has strong deoxidizing and purifying effects, which can improve the morphology of inclusions and reduce the content of gas elements in molten steel. However, the requirements for aluminum-ferroalloy are very high and strict in terms of production technical standards and quality. Due to the complex production process, high energy consumption, high pollution and the improvement of environmental protection requirements in the production of aluminum-iron alloy briquette by medium frequency induction furnace, its application space is gradually reduced.

Chinese Classical Musical Instrument-Erhu

Chinese Classical Musical Instrument-Erhu

Speaking of Chinese erhu, I believe everyone should know some more or less. Erhu can often be seen in cultural and artistic parties and film and television works. Erhu, a musical instrument, began in the Tang Dynasty and has a history of more than 1,000 years. It originated from a minority in the ancient northern region of our country and was then called "Xiqin". Tang Dynasty poet Cen Can's poem "The Chinese Army Buys Wine to Lead Back to Guests, Hu Qin Pipa and Qiang Di" shows that Hu Qin has begun to spread in the Tang Dynasty, and she is the general name of Chinese and Western stringed instruments and plucked instruments.

Research on High Pressure Grinding Rollers

Research on High Pressure Grinding Rollers

Energy is an important material basis for human survival and development, and is also the focus of international politics, economy, military and diplomacy. Therefore, the requirements for energy conservation, consumption reduction and efficiency improvement in concentrator are getting higher and higher. In all the processes of the concentrator, the grinding process consumes a lot of energy, and the consumption of lining plates, steel balls and other materials is also relatively high. Its energy consumption accounts for about 50%-70% of the total energy consumption of the whole concentrator, while the energy consumption of the grinding process accounts for more than 60% of the whole grinding process. Therefore, the grinding system also directly determines the production cost of the concentrator and the consumption of various energy and materials.

Design of Twin Shaft Horizontal Blade Mixer

Material mixing refers to the homogenization of one or more materials to reduce the uneven distribution of particle size, density, temperature and plasticity. It is a common material treatment method. Different industries have different mixing equipment due to different types, characteristics, uses and subsequent treatment methods of raw materials. The double-shaft horizontal blade mixer adopts intermittent discharging mode, and its structure adopts two stirring shafts with stirring blades arranged on them. The stirring blades forcibly mix and homogenize the materials during their rotation. The equipment is very suitable for mixing and homogenizing powdery, granular and liquid materials.

Chinese Characters

Chinese Characters

2020-08-28

As we know, China is one of the four ancient civilizations in the world,and China has a very long history. We have to discuss Chinese characters when talk about Chinese history. From Origin of Chinese Characters, which said many years ago, people can only speak without text communication, because the Cangjie inspired by birds and beasts, and then created Chinese characters. Now, I would like to introduce the three parts of Chinese characters: the Oracle Bone Inscriptions, the changes in the shape of Chinese characters and Chinese character components.
