Monitoring the Ring Formation in Rotary Kiln for Pellet Firing
Abstract The gratekiln process has been widely applied for oxide pellet production with the quick development of steel industry in China, but ring formation takes place which adversely affects the productivity and properties of fired pellets Rotary kiln at high temperature seems a black box, and ring formation is difficult to measureiron ore His process involved grinding taconite to remove gangues and upgrading the iron ore (ie, an ore beneficiation process) The resultant highgrade ore is in the form of fine particles, as small as 01mm or less, which are not suitable for sintering This issue led to the use of pelletizing Pelletizing plants are expected to play anKOBELCO Pelletizing Process
