Grate Kiln process is unique process designed to evenly indurate pellets to increase its mechanical properties This process employ a conventional ‘Straight Grate’ followed by a ‘Rotary Kiln’ designed to churn the pellets thus increase even heating as well to avoid fragmentation in transportation

Jan 01 2015 · In contrast the gratekiln system has been demonstrated to be capable of producing fired pellets using a variety of pellet feeds such as magnetite hematite specularite goethite pyrite cinder and their mixtures Fu and Zhu 2007 The largest annual capacity of

The innovation and creation of process and equipment of Ezhou pelletization plant of BAOWU plays an exemplary role for the application of largescale gratekilncooler in iron and steel industrial

Mar 21 2015 · The gratekiln system is easy to control and the product pellets have a uniform quality It can also be scaled up to a fairly large degree Gratekiln systems can be designed for production capacities up to 6 million tons per year per line These systems are used by many plants Pelletizing processes are being improved constantly

energy intensive part of the pelletization process The two most common processes for heat treatment are called the gratekiln and straightgrate processes The gratekiln process uses a travelling grate for drying preheating and cooling and a rotating kiln for sintering while the straightgrate uses a travelling grate for the entire process The

pelletization theory grate kiln technology producers who use iron ore pelletizing kiln rotary kiln process in iron ore pelletization NOx Formation in Rotary Kilns for Iron Ore Pelletization The production of iron ore pellets is often performed in the socalled GrateKiln process The aim of the process is to oxidize the magnetite Fe3O4 to hematite Fe2O3 and to sinter the pellets

Nov 26 2014 · In the STG process a stationary bed of pellets is transported on an endless travelling grate through the drying oxidation sintering and cooling zones In the GK process drying and most of the oxidation is accomplished in a stationary pellet bed transported on a travelling grate Thereafter the pellets are loaded in a rotary kiln for sintering and then on a circular cooler for cooling
