Pelletization
During drying, the binder holds the grains in the agglomerates together while the water is removed and continues to bind them together until the pellet is heated sufficiently to sinter the grains together. ... In the underwater pelletising system (Fig. 4.29), the extruder conveys the molten plastic through the start-up valve into the die plate ...

What is Pelletizing?
Pelletizing is a method of agglomeration, or particle size enlargement, in which material fines are processed into pellets or granules. Pelletizing is used throughout a multitude of industries to process thousands of materials from difficult to handle powders and fines, into easy to handle pellets. With many benefits, and a highly customizable ...

Wet Milling
Wet milling of wheat is the process of separating flour into its components, primarily starch and gluten, using water in the process. This can easily be illustrated in a kitchen. Take some flour and add enough water to form a dough ball and then knead the ball for a few minutes to allow the gluten to form.

Binding mechanisms in wet iron ore green pellets with a bentonite
Another explanation for the shift in the liquid saturation could be eventual shrinkage of the wet green pellets during drying. A 10.0-mm green pellet would need to shrink by 100 μm (1%) to explain the shift in the liquid saturation values. A dilatometer measurement showed a maximum shrinkage of about 10–20 μm, but the measurement …
