No cracks were found on the surface and inside of the standby ring through macro inspection and ultrasonic flaw detection. No microcracks and abnormal nonmetallic inclusions were found during high-power observation, which indicates that there are no metallurgical and preheating defects in the roller material.

Production type horizontal double-shaft paddle mixer, the equipment has two shafts, each shaft has 4 stirring paddles and 8 blades. When starting, the mixer uses the two shaft bodies to rotate in opposite directions to drive the blades on the stirring shaft to stir and mix the materials. During stirring, the powder is in a boiling state, and diffusion mixing, shear mixing and convection mixing are carried out at the same time.

Solid preparations of solid beverages, health food and drugs all need to mix the components of solid powder. The proportion of components in the formula can reach 80%-90%, and the proportion of components is less than 1%. The forms are powdery, granular and flaky.

The production of calcium magnesium phosphate fertilizer by blast furnace method has certain requirements on the particle size of phosphate rock and flux entering the furnace. Screening off fine ore less than 10mm is one of the important prerequisites for smooth operation, high yield, stable yield and low consumption of blast furnace. However, at present, the content of fine ore in the raw phosphate ore is as high as 20-40%, so the treatment of fine ore has become an urgent problem to be solved in the current phosphate fertilizer plant.

As the state pays more attention to and invests more in environmental protection industry, New flue gas desulfurization projects are increasing rapidly, and correspondingly flue gas desulfurization gypsum is also growing rapidly. According to statistics, nearly 10 million tons of desulfurization gypsum were produced nationwide in 2010. The development of the domestic desulfurization gypsum market provides an excellent opportunity, and at the same time it also brings difficulties to power companies simply selling digested desulfurization gypsum.

HPS mixed pellet sintering belongs to the small pellet sintering process, which is to mix iron ore powder, returned ore, flux and fuel with water to make small balls with a diameter of 5-10mm, wrap a certain proportion of solid fuel on the surface of the small balls, and then sinter. Compared with the common sintering method, the small pellet sintering method has increased the process links of strengthening granulation and rolling pulverized coal outward. Intensified granulation is to add a disc pelletizer between the first and second mixtures to make the mixture into small balls of 5-10mm. Fuel addition is to add 20%-30% of internal pulverized coal in the batching chamber. After pelletizing, 70%-80% of external pulverized coal is added.

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.

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.
