COMBUSTION AND AGGLOMERATION OF COAL-OIL MIXTURES

Addition of water may cause droplet swelling and fragmentation due to internal bubbling which, however, can be inhibited by moderate amount of internal circulation induced by the external convective motion. The possibility that agglomeration may be prevented under high pressure combustion is also discussed.

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical

Mixing Expert: Agglomeration -Unique Mixers Furnaces Pvt Ltd

Jun 09, 2012  Agglomeration is the process of combing of finely dispersed particles into larger particles. Agglomeration is caused by a rearrangement of surface forces resulting from a change of environment. Agglomerates in the powder raw material, or those formed during the mixing process, are undesirable as they can lead to non-homogenous mixing of materials.
