Resumo

THE SCREENING OF AGGLOMERATES, INCLUDING IRON ORE PELLETS AND SINTER FEED, IS A CRUCIAL STEP IN BOTH IRON ORE PELLETIZING PLANTS AND SINTER PRODUCTION PLANTS. IT ENSURES THE APPROPRIATE FINAL GRANULOMETRY FOR STEEL MILLS AND IMPACTS ENERGY CONSUMPTION IN BLAST FURNACES AND DIRECT REDUCTION MODULES. PROPERLY DONE, THIS PROCESS ENHANCES BED PERMEABILITY, INCREASES PLANT PRODUCTIVITY AND REDUCES THERMAL CONSUMPTION. DESPITE ITS IMPORTANCE, FINAL SCREENING IS OFTEN OVERLOOKED BY OPERATION TEAMS DUE TO ITS FEW CONTROL VARIABLES, WHILE AT THE SAME TIME REQUIRES FREQUENT INTERVENTIONS BY MAINTENANCE TEAMS TO ADDRESS THE MECHANICAL ISSUES, LIKE PARTS REPLACEMENT -EXCITER, SPRINGS AND SCREENING MEDIA - ASSOCIATED WITH VIBRATING SCREEN TECHNOLOGY. THE PAPER INTRODUCES METAL7'S INNOVATIVE ROLLER SCREEN TECHNOLOGY ADAPTATION, HIGHLIGHTING ITS POTENTIAL FOR THE AGGREGATE SCREENING PROCESS. IT ADDRESSES THE LIMITATIONS OF TRADITIONAL VIBRATING SCREENS BY OFFERING ENHANCED EFFICIENCY AND RELIABILITY IN SCREENING HARD PARTICLES AND AGGREGATES ACROSS VARIOUS INDUSTRIES. THE ADAPTATION AIMS TO DEAL WITH CRITICAL CHALLENGES SUCH AS DUST GENERATION, EXCESSIVE NOISE, MATERIAL BREAKAGE, MACHINE BREAKDOWNS, AND MAINTENANCE-RELATED SHUTDOWNS, ENSURING HIGHER SCREENING EFFICIENCY AND OPERATIONAL CONTINUITY.
