Powder mixing is a common operation in industrial production, which is widely used in the chemical industry, pharmacy, food, and construction. It is one of the most critical operation procedures in the production of medicines, feed, cement, and other products. Powder material mixing refers to the operation process in which a variety of powder particles with different components change their moving speed or direction in the mixer, and finally, make the particles with different components randomly and evenly distributed in the mixer.

A ferroalloy company produces high-carbon ferrochromium. Each submerged arc furnace is equipped with a negative pressure bag dust removal system to collect and treat the flue gas and dust in the submerged arc furnace.

In order to make the large and medium-sized reduction electric furnaces of ferroalloy run better, it is required that the burden has proper fragmentation and ensures good air permeability. At present, the supply of high-quality lump burden which can be directly fed into the furnace is becoming increasingly tight. In order to adapt to this situation, some manufacturers at home and abroad have adopted various lump technologies to effectively utilize fine ore and concentrate and obtained better smelting indexes.

According to the different subsequent smelting processes, vanadium-titanium iron concentrate pellets determine their respective application fields. Vanadium-titanium iron concentrate acid oxidation pellets are mainly used in blast furnace smelting, blast furnace burden protection and gas-based shaft furnace reduction, but vanadium-titanium iron concentrate carbon pellets are mainly used in coal-based direct reduction.

According to comprehensive analysis, LT dust can be reused while reducing environmental pollution by returning to converter for smelting after being lumped nearby, which is the best choice for its utilization mode.

Dust removal methods in the converter steelmaking process can be divided into the wet method and dry method. The traditional wet purification system is as follows: after the flue gas is treated by water spraying, the smoke dust is removed, and the sewage with smoke dust is treated by separation, concentration, and dehydration to obtain converter sludge, and the purified gas is recycled.

The tunnel kiln process is relatively simple, the technical content is low, and the raw materials, reducing agents, and fuels are easy to solve. The process has strong practicability, small early investment, and is suitable for small-scale production. It is a metallurgical reduction production process commonly used in the powder metallurgy industry.

Gas-based direct reduction iron (DRI), which has been commercialized, is made from natural gas or coal. In recent years, with the global attention to carbon dioxide emissions, active research has been carried out on the low carbonization of DRI processes, mainly carbon dioxide removal in existing commercial DRI processes or the use of renewable energy to produce reducing gas.

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.
