pelletization of iron ore in grinding :

Iron ore pelletization - ScienceDirect

2015-1-1  Straight grate, grate-kiln, and shaft furnaces account for approximately 58%, 35%, and 6%, respectively, of world pellet production in 2013 (Oja, 2013). Therefore, the grate-kiln and straight grate systems are the dominant technologies currently being used in the iron ore pelletizing industry.

KOBELCO Pelletizing Process

2011-1-6  The location of a pelletizing plant affects the method of receiving raw materials such as iron ore, additives and binders. Many pelletizing plants are located near ore mines. This is because these plants were developed to pelletize the raw materials that are beneficiated at these mines. Such plants receive the raw materials via railways and/or slurry pipelines. Other pelletizing plants exist at a distance

Study on the Induration Cycle During Pelletization of ...

2016-1-28  Iron oxide pellets are one of the main feed sources for blast furnaces or direct reduction processes of the iron and steel making industry. Pelletizing is the first step in the production of these pellets. The process basically consists of mixing finely ground iron ore concentrate with several additives and water in pelletizing disks or drums until balls of a specific size are obtained (called green pellets). Prior to shipment to steel plants, green pellets need to be fired in order to increase their mechanical strength for transportation and handling considerations. Pellet induration is typically performed in moving grate or grate kiln furnaces1, through which pellets are sequentially dried, fired and cooled by direct contact with hot gases of varying flow rates and temperatures. Pellets quality (i.e. mechanical strength) strongly depends on their residence time and temperature profile within the firing zone as well as their residual moisture content at the time pellets reach the firing zone, since induration reactions only begin when drying is completed. Pellet
