Here the present study investigated co-production of the carbon composite pellet and sinter with existing sintering machines. Even if fired in an oxidizing atmosphere, carbon-core-pellets can be produced under conditions that simulate the conventional sintering process. This is because a protective shell over the carbon core inhibits the carbon ...
Each process differs in size, shape, particle size distribution and uniformity of the pellets produced. Flow mixers or ring-layer mixing granulators can be used as wet granulators or pelletisers. If particularly large agglomerates are desired, multi-stage agglomeration can be used. A pelletising plate is then used.

For sinter process optimization and engineering of following conveying plants sinter breakage behavior is a very important aspect. Usually tumbler tests (ISO 3271, 2015) are carried out to determine the cold strength of sinter.The Micum-test is common practice in Europe and is standardized in (ISO 556, 2020).For this test, a bulk sample is filled into a steel drum …
4 Key Points to Understand the Difference Between Sinter and Pellet 1. Process and End Products. Sintering combines fine particles into a solid mass using heat and pressure below the melting point of the materials. Pelletizing compacts fine materials into small, dense pellets, often used in the steel industry. 2. Sintering Process

agglomerates, such as iron ore sinter and pellet, and lump are re-duced from hematite to magnetite, cracks are formed in the particles and they pulverize in the blast furnaces.4–12) JIS and ISO standards specify using the RDI as an operation management index in off-line tests to evaluate reduction disintegration behavior. The index is ob-
Although tests adopted by the International Standards Organization, including cold crushing (ISO 4700) and tumbling and abrasion (ISO 2371), are often used in quality control in the supplieŕs plant and for setting up commercial contracts, they offer little or no information to predict quantitatively breakage resulting from individual handling and transportation operations of …

Moreover, in comparison with sinter, the agglomerates also have equal or greater strength after reduction at 700°C and 900°C because solid phase sintering was promoted by adding ultrafine iron oxide powder. Therefore, as a blast furnace raw material, the permeability and reducibility of the agglomerates of return fines of sinter are superior ...

Themineral phases composing this structure should be mainly …
2 Pellet was observed for the sinter and pellet rather than the lump and it was suggested that this was due to the significant content of silico-ferrite of calcium and aluminium (SFCA) in the sinter and pellet. 10) When this SFCA has been reduced in the presence of H 2, its fracture toughness value was decreased.
