In recent years, with the implementation of a series of new environmental protection policies, higher requirements have been placed on the environmental management methods of foundry companies and the occupational health and safety of employees. The pollution control technology and facilities of foundry enterprises during the production process are still relatively backward. Under such realistic conditions, there is an urgent need for environmentally friendly binders, and phosphate inorganic binders have emerged.

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.

Many materials may require binder in the production of cold - consolidated pellets. The choice of binder is varies from different and processes. According to our practice, we are going to make a general description of the choice of binder.

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.

Since the tailings are very fine in size, it is more reasonable for the raw tailings to be pelletized followed by direct reduction roasting. In order to investigate the possibility of iron recovery by direct reduction roasting of carbon briquette from high iron tailings, the effects of different binders on the green briquette strength and high temperature strength of carbon briquette from high iron tailings were studied.

For cold-consolidated pellets, molasses can be used alone as a binder, some of which may need to be diluted during use and a certain temperature is required. Molasses can also be used as a binder together with other materials. For some pellets that need special use, molasses may also be used as the main raw material to add other materials to prepare a binder with composite properties.

Pulp waste liquid is a good binder in the cold consolidation briquette industry, because of its low price, there are industrial cases instead of molasses as binder applications.

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.
