Abstract

"PELOTAS DE MINéRIO DE FERRO COM REDUçãO DA ABRASãO, COLAGEM, DEGRADAçãO E EMISSãO DE POEIRA, E PROCESSO DE SUA FABRICAçãO". As pelotas de minério de ferro são produzidas por processo no qual o minério de ferro é misturado com os aditivos necessários para adequar a composição quimica desejada, sendo, a seguir, pelotizado em disco rotativos; os elementos resultantes são pelotas formadas que são transportadas para um forno de grelha móvel, onde passam pó um processo de queima, recebendo então adição de misturas de polímeros ou copolímeros acrílicos, polímeros e copolímeros de acetato de vinil ou ainda óleos sintéticos - para se tornar resistência a abrasão, colagem, degradação e emissão de poeira."IRON ORE PELLETS WITH ABRASION REDUCTION, COLLAGE, DEGRADATION AND DUST EMISSION, AND THE MANUFACTURING PROCESS". Iron ore pellets are produced by a process in which iron ore is mixed with the necessary additives to suit the desired chemical composition and is then pelletized on rotating discs; The resulting elements are formed pellets which are transported to a movable grate oven, where a firing process is powdered, then added with mixtures of acrylic polymers or copolymers, vinyl acetate polymers and copolymers or even synthetic oils - to become resistance to abrasion, bonding, degradation and dust emission.
