Sintering Mixed Granulation Process (1)

Sintering Mixed Granulation Process (1)

2020-12-21

Mixed granulation process is a very important link in sintering production process. Intensive mixer is to mix all kinds of materials in the batching process evenly. Granulation is to make materials into mixed materials with appropriate particle size and good air permeability.

Nibrasco Briquetting Plant

Nibrasco briquetting plant was completed and put into production in August 1978. This article will describe the process flow of each section of the factory.

Briquetting of Sponge Iron Powder

Briquetting of Sponge Iron Powder

2020-12-21

Sponge iron powder has small particle size, light weight, floating on the surface of molten steel and discharging outward with slag, with low recovery rate, and cannot be applied to industrial production. However, due to the long-term stacking of products, natural oxidation and waste are very serious. Therefore, after the sponge iron powder is pressed and molded, its oxidation resistance will be improved, its chemical composition will be stabilized, steelmaking problems such as floating and caking will be solved, and melting speed and recovery rate will be improved.

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.

Preparation of Metalized Pellets from Titanium Concentrate by Pre-reduction

Preparation of Metalized Pellets from Titanium Concentrate by Pre-reduction

2020-12-10

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%.

Ammonium chloride granulation scheme

Ammonium chloride granulation scheme

2020-12-10

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.

Development of Crushing Equipment(2)

Development of Crushing Equipment(2)

2020-11-30

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

Direct Briquetting and Reduction Roasting of Rhomboid

2020-11-30

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.

Carbon-Containing Pellets with Laterite Nickel Ore(3)

Carbon-Containing Pellets with Laterite Nickel Ore(3)

2020-11-30

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.
