PELLET OBTAINING METHOD Russian patent published in 2017 - IPC C22B1/24 

FIELD: metallurgy.

SUBSTANCE: wet charge is fed to the pelletizer in two flows, forming a skull at the bottom of the pelletiszer, to form a working zone on the bottom of the pelletizer, occupied by pellets, and an empty zone, free from pellets, a nucleation, performed by forming a dense layer of wet charge in the zone free from pellets, rotating drums, installed with a gap to the skull surface, feed to the first flow of charge to said gap. In this case, the gap between the skull and each subsequent drum is set less than the previous one. Dividing the dense layer with the help of dividers, cleaning the skull from a dense layer of wet charge, and perform the after-pelletizing with the second flow of charge to obtain pellets. The rotating drums are tensioned with endless elastic band made with transverse metal ribs, the tension of which is carried out by means of a pressing device, and the dense layer of the charge is shielded from the sides with longitudinal metal guides.

EFFECT: increasing strength of pellets and efficiency of the pelletizer.
