2020-12-10

As a kind of briquetting equipment, the high-pressure briquetting machine continuously sends various dry and wet powder materials to the roller pressing area through the preloading device. Under the pressure of the roller pressing area, the dry and wet powder are pressed into briquettes, which are mainly used in coal, mining, metallurgy, refractory materials, building materials and other industries.

Titanium slag is a titanium product obtained by melting and enriching titanium concentrate and reducing agent in an electric furnace. It can be divided into acid-soluble titanium slag and chlorinated slag according to its application. The TiO2 content of acid-soluble titanium slag is 70-80%, and the TiO2 content of chlorinated slag is generally above 85%.

The combined soda production method has the characteristics of light pollution and high utilization rate of raw materials, and has become the preferred production mode for the relocation of old enterprises in the soda production industry, making the output of ammonium chloride, a by-product of soda ash, increase year by year this year. According to statistics, the plant scale reached more than 14 million tons in 2009, with the output reaching 8.55 million tons, and there is an upward trend year by year. There are many restrictions on direct fertilization of powdery ammonium chloride as chemical fertilizer, most of which are used as raw materials for compound fertilizers. Granulation of ammonium chloride is one of the effective ways to solve the problem of agricultural ammonium chloride. Granular ammonium chloride has the advantages of mechanized fertilization, blending with other fertilizers to produce BB fertilizer, prolonging fertilizer efficiency, etc.

Crusher is an indispensable kind of equipment in industrial production. Understanding its current situation and development plays an important role in future work. For a long time, the crusher has been constantly innovating, but in the design process, we should constantly improve the shortcomings in the crusher.

Direct Briquetting and Reduction Roasting of Rhomboid

From the naturally cooled burnt balls after reduction roasting at different temperatures, it is found that the hardness of the burnt briquetts increases with the increase of temperature, and the higher the temperature, the more obvious the deformation of the burnt balls. The hardness of the roasted ball at 1200 ℃ is greater than that of the roasted ball at 1000 ℃, and the shrinkage deformation after firing is more obvious. It may be that the higher the temperature, the more conducive to the diffusion and condensation of metal iron generated in the roasted ball, so the roasted ball shows higher hardness and obvious shrinkage.

Laterite nickel ore contains higher kaolinite, and kaolinite belongs to clay mineral, so it has greater plasticity. The bonding force between molecules can be fully exerted in the ball pressing process, so that the laterite mineral powder is easy to form balls, and the mineral powder has a certain particle size composition, irregular particle shape, rough surface, and the particles can fully fit in the briquetting process, thus improving the briquette strength.

China is rich in iron ore resources, but most of them are low-grade ores, including many hematite, limonite, siderite, etc., which are characterized by low iron grade, fine crystal size, compact distribution with gangue, and difficult dissociation of monomers. Therefore, it is difficult to use conventional beneficiation methods for separation and cannot be reasonably utilized. With the rapid development of iron and steel industry, there are fewer and fewer rich ores available for utilization. Therefore, it is of great significance to effectively develop and utilize low-grade iron ore and complex symbiotic ores.

For the pelletizing performance of mineral powder, the greater the plasticity of mineral powder, the smaller the resistance during pelletizing, and the easier the particles are to produce plastic deformation. It can exert greater molecular adhesion, thus improving the ball pressing performance of the material. The plasticity of ball pressing materials mainly depends on the structural composition of the materials.

Nickel, as an important strategic metal material, has various advantages such as corrosion resistance, oxidation resistance, high temperature resistance, high strength and good ductility, and is widely used in modern industry. Nickel is mainly used to produce stainless steel. 65% of the world's total nickel consumption is used to produce stainless steel and 12% is used to produce heat-resistant alloys and non-ferrous metal alloys. It is an indispensable and important metal. At present, the known nickel reserves in the world are about 160 million tons, of which nickel sulfide ore accounts for about 30% and laterite nickel ore for about 70%. Due to the low nickel content in laterite nickel ore, difficult recovery and poor economic benefits, the nickel produced by laterite nickel ore accounts for only 42% of the world's nickel output. However, in the long run, laterite nickel ore will be the main source of nickel in the future.

Hardener of Sodium Silicate-Magnesium Chloride

Hardener of Sodium Silicate-Magnesium Chloride

2020-11-09

The common hardeners of sodium silicate binder are ammonium chloride, magnesium chloride, alumina, etc. In order to reduce the dosage of ammonium chloride, ammonium chloride-magnesium chloride composite hardener scheme is selected. In this scheme, only ammonium chloride is used to harden the first two layers and magnesium chloride is used to harden the reinforced layer, thus significantly reducing the usage of ammonium chloride.
