Since the 1950s, granulation has been frequently employed in the pharmaceutical and agricultural industries. While the science is much the same as it was over 70 years ago, granulation processes and equipment have improved, allowing for a wider range of applications.
Generally speaking, there are 2 methods main methods of granulation: dry and wet granulation. Wet granulation employs the use of water or a binder to stick particles together while dry does not. In this article, you’ll understand more about wet granulation and how it can benefit you.
What is Wet Granulation in Fertilizer Granulation?
Granulation is the process of combining and attaching primary powder particles to form larger, multiparticle entities called granules. Wet granulation is a size-enlargement method that involves agitating a liquid into a powder to produce agglomeration or grains. It is the most popular and oldest method of tablet production.
Wet granulation is becoming very popular in the agriculture industry, particularly in fertilizer production. It creates granular fertilizer with a higher moisture content than dry granulation, requiring the end product to be cooled and dried to solidify.
What Are Advantages Can I Get When Using the Wet Granulation Machine?
- Better Granule Forms
Wet fertilizer granulation includes forming granules directly on a granulator pan from the feedstock without the use of intermediate stages or seed ingredients. As a result, the product has a perfectly uniform cross-section.
The granules are more spherical and have better flow properties than powders. The moist granules are dried correctly and combined with other essential excipients before being compressed into granules, whether they are manufactured with a rotating drum, disc pan granulation, or spray granulation.
- Improved Content Consistency
Wet granulation changes the properties of formulation ingredients and allows them to overcome granulation problems. Moisture is kept at a constant level to ensure that the process does not cycle.
By preventing segregation of components of a homogenous powder mix during processing, transferring, handling, and/or storage, wet granulation lowers intra- and inter-batch variability. The approach has the advantage of permitting the safe and efficient granulation of materials that are either toxic or fundamentally difficult to granulate.
- Longer Lifespans for Machines
Low compression pressure can be used due to the improved compressibility of powders as a result of the wet granulation process. As such, machine wear is reduced, and the machine’s life is extended.
- Improved Product Solubility
The approach may improve the dissolving rate of poorly soluble fertilizers by introducing hydrophilic characteristics to the surface of the granules.
- Healthier Working Environs
Wet granulation minimizes the amount of dust produced during the manufacturing process, lowering the danger of cross-contamination and worker injury.
Wet granulation is used to improve homogeneity, flow, consistency, solubility, compressibility, and even bioavailability of granule forms. We produce amazing wet granulation plants that use a one-of-a-kind blend of tried-and-true technology and bespoke solutions, regardless of your application or need.
Standard components such as our high shear mixer granulators and fluid bed dryers are used to come up with plants that are customised to the customer’s specific needs. Contact us today!
