· 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.

The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization:
More Details· Choosing the right pelletizing process involves consideration of more than pellet shape and throughput volume. For example, pellet temperature and residual moisture are inversely proportional; that is, the higher the product temperature, the lower the residual moisture. Some compounds, such as many types of TPE, are sticky, especially at ...
More Details· Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
More DetailsThe process of ''agglomeration'' can be classified mainly into the following groups, namely, Briquetting, Nodulizing (rotary kiln sintering), Vacuum extrusion, Sintering and Pelletizing. Briquetting : This is a very simple process, in which fine grained materials are pressed into briquettes
More DetailsThe pelleting process starts with a bin (Figure 1, Item 1) in which the mixture of mash is stored. From there, the mash will flow by gravity into the pellet mill (Figure 1, Item 2). This machine is usually located on the ground or main work floor level. The hot, extruded mash (pellets) flows by gravity into a …
