“…Notably, pelletizing units using drum technology encounter higher recirculating loads, necessitating efficient screening to maintain productivity [9,10]. Ensuring pellet homogeneity through effective screening positively impacts furnace energy consumption and the performance of the pellet bed in the induration furnace [11,12]. The role of screening, particularly through roller screens, is fundamental to ensuring the production of high-quality iron ore pellets by managing size distributions, enhancing furnace performance, and ultimately impacting the economic viability of pelletizing processes.…”

The iron ore screening process plays a pivotal role in determining the dimensions of pellets that enter the firing process of a pelletizing plant. The particle size distribution resulting from this process significantly influences the gas flow permeability within the induration furnace. This paper investigates the latest developments in screening technology, highlighting advancements that contribute to elevated levels of screening efficiency and enhanced plant productivity. The discussion turns around how these technological innovations pave the way for achieving the objective of producing high-quality iron ore pellets with minimal energy consumption, thereby improving the overall performance of the plant. The paper offers a comprehensive overview of the screening process flowsheet, encompassing these cutting-edge technologies, associated process parameters, and benefits quantified through DEM simulations. Moreover, it examines the consequential impact on greenhouse gas (GHG) emissions, providing a holistic perspective on the environmental implications of these advancements.

“…The studies from Goncharenko et al [7] shows that use of up to 11-11.5% moisture in the pellet charge does not lead to spontaneous pellets accretion on the roller screen, as it inevitably occurs on the vibrating screens. Dias et al [14] has proposed an automatic water addition at the drums based on the growth rate of pellets, due to the importance of this parameter at the final pellets quality and homogeneity. The surface of pellets unloaded from the roller screening is more uniform and contains practically no aggregated charge particles.…”

“…In regards to furnace benefits, a higher granulometry homogeneity of pellets allows an optimum energy consumption due to the better permeability of the pellet bed profile [14], while a higher pellets heterogeneity negatively affects the grate car permeability [15]. The screen is responsible in guaranteeing a good pellets homogeneity in the induration furnace.…”

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.
