“…There is a very limited quantity of technical studies related to the roller screening process [24,[26][27][28][29][30]. Therefore, the objective of this publication is to provide detailed information about the principal roller screening parameters and their impact on the roller screening efficiency.…”

“…Thomazini [29] has reported, through discrete element analysis (DEM), the screening efficiency of an iron ore pelletizing plant using a single deck roller screen (SDRS) at the discharge end of a balling disk using a gap strategy of 9.00 mm for undersize removal and 16.00 mm for oversized removal and feed tonnage of 130 ton/h. Additionally, a double-deck roller feeder (DDRF) was simulated also at a gapping of 16.00 mm for the oversized removal screen and 9.00 mm for the undersized removal screen, feed tonnage of 910.00 ton/h.…”

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. Improvements to the equipment performance not only promotes benefits to the plant’s productivity, but also in the final product’s quality. Several parameters influence the equipment’s performance, impacting directly or indirectly the screening ratio (ton/m2 of open screen area). The objective of this work is to provide information regarding the key parameters influencing the roller screening performance through practical expertise and literature review, due to the lack of studies related to this important equipment. It is a review manuscript describing the screen variables and its impact on the iron ore pelletizing process.
