  Drying and preheating processes of iron ore pellets in a …

  2010109 · A mathematical model of drying and preheating processes in a traveling grate was presented based on the laws of mass, momentum, heat transfer, and drying semiempirical relations. A field test was systematically carried out in a traveling grate. The effects of pellet diameter, moisture, grate velocity, and inlet gas temperature on the pellet …

  An integrated optimal control model for the drying and …

  2024112 · Abstract The drying and preheating process plays a crucial role in the induration of iron ore pellets. It is conducted on a closed, moving bed in both the straight grate and grate-kiln processes. The internal state of the pellet bed cannot be measured and the manipulated parameters are set according to the experience. An integrated optimal …

  Fine Size Dry Iron Ore Beneficiation Using Thin Bed Air Fluidized Dry ...

  2024313 · In the present study, iron ore feed with a size range of − 1 mm to + 0.1 mm with an assay of 58.28% Fe is subjected to dry processing on a thin/shallow bed air fluidized dry separator (TBAFDS). This unit is a gravity-based separator that utilizes the difference in minimum fluidization velocities of heavier and lighter particles.
