The roller screening process is an important step in the iron ore pellets production. This step is intrinsically linked to the balling production and the induration machine.
Double deck roller screens are often used in iron ore pelletizing circuits to control the size of green pellets entering the induration furnace. Besides removing fines that would increase the pressure drop in the furnace, they can also improve the permeability of the bed by inducing stratification. In spite of the widespread use of roller screens in …
