The Iron Pelletizing Process
The most commonly employed agglomeration technique is pelletizing by which a mixture of iron ore, water, and binder is rolled up in a mechanical disc or drum to produce agglomerates (green or wet pellets).

Several process-control issues can individually or collectively cause the problem. The process water may be too hot. Lower the temperature to adequately quench the surface of the pellet. Another cause may be low water flow, which can contribute to pellets moving slowly out of the cutting chamber, resulting in agglomeration.
