The pellets …
Pellets required for the present study were collected from a commercial straight-grate pellet plant of 3 Mt/year capac-ity. Production of iron oxide pellets from iron ore fines in-volves different operations like drying of ore fines to re-move the moisture and grinding to get the required fine-ness.

The exhaust heat is also recovered and used for pellet drying and preheating [5]. With the rapid development of the iron and steel industry, the annular cooler has been widely used in most large and medium palletizing factories at home and abroad. However, 3-D models of the pellet cooling process in an annular cooler are rare in literatures.
Annular cooler, circular cooler, sinter cooler . Annular Cooler is one of the main equipments in pelletizing process project, which is used for cooling the hot pellet from the rotary kiln, and also for absorbing the heat from the hot pellet, for reusing in the former process, to reduce the energy consumption of the whole process.

Jan 01, 2015· This Pelletizing Process develops best pellets for DR plants (HK Naik et al) A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in almost the same manner that one rolls a snowball, to make a pellet …
Pelletizing is the process of transforming iron ore fines into spherical pellets through agglomeration and induration to ... Traveling Grate, the Rotary Kiln, and the Annular Cooler. Independent variable speed control of drying/preheating, induration, and cooling allows process flexibility to adjust to changes in ... line modeling…
In iron ore pelletizing there are many opportunities to recycle lost energy to produce a more efficient process. While there are areas for improvement in this process it can be very costly to trial these methods in full-scale production due to the large scale of the furnaces and large through put. Using equations to model the process is an ...
Annular cooler. An annular cooler is a turntable that holds the hot pellets. Ambient air is blown through the hot pellets. The turntable is made of wedge shaped pans. The pellets fall out of the kiln directly onto the pans. The pellets travel all around the turntable until the pan is tipped and the pellets fall underneath.
Taconite, a low grade iron ore of approximately 30% iron content or lower, is mined (by open-pit methods) and processed in the Mesabi Range in northern Minnesota and the Marquette Range in the northern part of the Upper Peninsula of Michigan. Pellets of approximately 65% iron …
