Granulointi

Granulointi is a process used in various industries to convert fine powders into larger, more manageable granules. This agglomeration technique aims to improve the physical properties of powders, making them easier to handle, transport, and process. By forming granules, issues like dustiness, poor flowability, and caking can be significantly reduced. The resulting granules often exhibit enhanced compressibility, which is crucial in applications such as tablet manufacturing in the pharmaceutical industry.

The granulointi process typically involves binding agents, which are added to the powder to help the particles stick together. Water, organic solvents, or specialized binders can be employed, depending on the specific material and desired outcome. Mechanical forces are then applied to mix and agitate the powder and binder, leading to the formation of granules. These granules can then be dried to remove any residual moisture or solvent, further solidifying their structure.

There are several methods for achieving granulointi, including wet granulation and dry granulation. Wet granulation involves adding a liquid binder to the powder to create a paste or slurry, which is then forced through a screen or dried. Dry granulation, on the other hand, does not use any liquid binders. Instead, it involves compacting the powder into larger sheets or slugs, which are then milled into granules. The choice of method depends on factors such as the material's sensitivity to moisture and heat, as well as the desired granule size and density. Granulointi is a vital step in producing high-quality powders for a wide range of applications.
