ABSTRACT. Roller screen is a key device in pelletizing plants employed to size classification of green pellets. Realistic observations showed that some pellets with size slightly larger than the gap were trapped between the rollers and caused blockage and decreasing the device efficiency consequently.

plants across the globe and continues to rule the marketspace. In the early days of the pelletizing technology, pellet plants were small-sized. The first pellet plants had an indurating machine width of 2.5-3 meters and annual capacities in the range of 1 million tons of pellets. The development of the product in the later decades
It is observed that the optimum plastic behavior of the pellet and consequently the efficiency of the roller screen would be achieved when the green pellet is made from magnetite concentrate with 8 % moisture and 1 % bentonite, and roller screen operational parameters include feed rate of 1.5 t/h, the deck inclination angle of 13 degrees and ...
Wide Belt Conveyors are commonly found in the iron ore pelletizing plants, which are used to collect green pellets from the reciprocating belt conveyor and to convey the pellets to the double deck roller screen/feeder or a single deck roller screen/feeder. Generally, it has a width relatively similar to the roller screen/feeder and furnace grate. The equipment is designed according to …
Roller screens are crucial for pelletizing plants. A more efficient roller screen process will enhance production by effectively removing most of the small and large pellets, maintaining a greater number of pellets with optimal dimensions, narrower dimensional distribution, and improved mechanical strength for downstream processes ...
