It has been found through practice that the finished ore produced by the grate machine rotary kiln process has the characteristics of uniform quality, good metallurgical properties, more usable fuels, and strong adaptability to raw materials. This article introduces what equipment should be equipped with this production line equipment.

The study explores the influence of binder type, binder dosage, and moisture content on the characteristics and properties of the pellets. The efficiency of binders was characterized by the moisture content, drop number test, cold compression strength, and H2 reduction of pellets. For dry pellets, CMS was superior among other binders including bentonite in developing dry strength. After firing, the pellets produced by the partial replacement of bentonite with 0.1 wt.% KemPel demonstrate a performance nearly identical to the reference pellets. While the complete replacement of bentonite with organic binder shows a lower performance of fired pellets compared to the reference, it may still be suitable for use in DR shaft furnaces. The cold-bonded pellets demonstrate a superior reduction rate compared to fired pellets.

The transformation from traditional iron- and steelmaking technologies to green H2-based new technologies will require an improvement in the quality and purity of iron ore burden materials. Iron ore pellets are essential inputs for producing direct reduced iron (DRI), but the conventional binders, used in iron ore pelletizing, introduce gangue oxides to the DRI and consequently increase the slag generation and energy consumption in the steelmaking unit. Partial and/or full replacement of the traditional binders with novel organic binders would significantly contribute to improving the process efficiency, particularly in the next-generation H2-based direct reduction technology. This study illustrates the feasibility of pelletizing magnetite iron ore concentrate using four organic binders: KemPel, Alcotac CS, Alcotac FE16, and CMC, in comparison to bentonite as a reference.

With the demand of structural adjustment and optimization of China's iron and steel industry, and the requirements of green, low-carbon and high-quality, pellets as high-quality raw materials for blast furnace are more and more favored by the industry, which promotes the rapid development of the pellet industry.

In the production of float glass​, the mixing process is a very important link in the production of the mixture, and the mixer is also a very important key piece of equipment. The correct selection and use of the mixer is the basis for improving the quality of the mixture and ensuring the stable quality of the glass.

Through practice, it is found that the finished ore produced by grate rotary kiln process has the characteristics of uniform quality, good metallurgical properties, more fuel available and strong adaptability to raw materials. This paper introduces what equipment should be equipped with the production line equipment.

The Pellet method represents the development direction of fine powdery iron concentrate, bentonite as a dry binder plays a decisive role in the process of caking, therefore, it is of great significance to study the bonding mechanism of bentonite to iron ore pellets.

Cold-solidified briquetting is the main method for steelmaking sludge treatment in metallurgical enterprises at present.

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.

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.
