6. Conclusion

Wet granulation is a powder shaping technique widely used in many industrial sectors: pharmaceuticals, food processing, metallurgy and steelmaking, mineral chemistry, detergents, fertilizers, cosmetics, etc.

The principle behind this operation is to use a binder to form bonds between particles. As the binder is introduced in the form of a solution or suspension, understanding the physico-chemical interactions at play within the wet granular medium remains the key factor in controlling the process.

The choice of a wet granulation technique should be based on the physical properties of the product to be granulated and the expected properties of the final product. The following points should be borne in mind when selecting a pelletizing technique:

• Fluidized-bed granulation enables several operations...
