Granulation of Fertilizers Using Rotatory Granulation Drum

Granulation of Fertilizers Using Rotatory Granulation Drum - NAQ GLOBAL


Granulation of fertilizer products gives some of the most feasible approaches to mix minerals for creating a multi-nutrient fertilizer. Additionally, it allows for bulk stockpiling and packaging by fertilizer coating material Suppliers, while providing the ease to handle and apply the product. One type of equipment that has turned out to be known for its consistency and adaptability in producing fertilizer is the rotatory granulation drum. This revolving process gear and the assortment of items that it can produce is a perfect fit for the fertilizer industry’s ever-evolving demands.

How the granulation drum manufactures the best quality fertilizer product? 

The meaning of a granule, as it identifies with the rotary drum, is a strong, round pellet, in the size scope of roughly 1-6 mm. These granules can differ in properties and synthetic cosmetics, contingent upon what is required for the application. An inorganic fertilizer, for example, NPK, which is also considered a multi-nutrient compost, comprises of nitrogen (N), phosphate (P), and potassium (K), and is a regularly pelletized item.

A granulation drum is mainly used to bundle these minerals, which regularly are in the form of fine powder. The minerals can be mixed into one granule, forming into an all-in-one product, or the individual granules can be mixed with others during a later stage in the packaging process. In the absence of this technology, the powdery materials would be difficult to handle due to their dusty nature, the denser particles would settle to the base of the barrel or the bag, resulting into the creation of an inconsistent mix and causing huge application challenges.

Apart from developing a highly consistent and durable granule, granulation drum can also be used to create granules that are more dynamic in a property. Diverse liquid binders can be utilized for the purpose of creating an enclosed granule that comes with different release properties. Also, a multi-layered pellet can also be produced with the addition of different materials at subsequent stages during the granulation process.

The Process of Fertilizer Granulation - During the granulation process of inorganic fertilizers, for instance, the creation of diammonium phosphate (DAP) or monoammonium phosphate (MAP), the granulation drum is used for a chemical reaction in connection with the arrangement of a strong granule. The chemical reaction, that basically starts in a pre-neutralizer tank, ends up neutralizing the phosphoric corrosive slurry with alkali, while all the while at the same time creating a granule that contains both phosphate and nitrogen, two indispensable supplements required in a multi-nutrient #fertilizer.


However, as mentioned earlier, another possible option that can build effectiveness in certain settings is the inclusion of a pipe reactor, which pre-blends the fluids and created DAP or MAP in a hot melt state. it is then the hot-melt is then encouraged into the granulation drum; the heat from the compound reaction alongside a particular amount of dry material of seed makes a pellet consisting of both the nitrogen as well as the phosphate.

The granulation drum's flexibility does not finish at DAP or MAP creation; potash powder can likewise be added into this procedure for the purpose of creating an NPK. The successive impact of the drum rotatory functions admirably with practically any combination of wet and dry inorganic minerals.

Advances in Granulation Drum Design 

Almost all industries have witnessed significant growth due to present day technology. Some of the most popular advancements in the design of the granulation drum are as follows -

Integrated Pipe Reactor - Completely blends and helps in the reaction of ammonia with phosphoric or potentially sulfuric acids, for enabling the creation of fluid or hot melt which is then sprayed within the drum. This takes out the requirement for pre-balance tanks and furthermore expands effectiveness. 

Tumbler flights - Used to expand the material disturbance to consummate the falling impact and make the ideal granule properties.

Corrosion resistant and Flexible Drum Liners – Can be utilized to diminish or exclude material develop from the walls of a drum, and also the damage that is the result of corrosive binders/materials.
