The various methods of reducing or eliminating caking in fertilizers basically involve process control, storage/packaging conditions, and/or addition of anticaking agents. Our Anticaking agents are aimed at providing a comprehensive solution to the problem of caking, moisture adsorption and nitrogen loss in granulated fertilizers.

The phenomenon of granule caking of ammonium nitrate fertilizers is associated with the occurrence of cohesion, a ected by the aforementioned physicochemical properties, as well as the storage conditions of the fertilizer. Another factor that determines the susceptibility of nitrogen fertilizers to the caking process is their composition.

Most fertilizers have some tendency to form lumps or agglomerates (caking) during storage. The mechanism of caking in fertilizers is most often attributed to the formation of salt bridges and/or capillary adhesion. The severity of caking can be influenced by a number of factors, such as chemical composition, moisture content, particle structure, mechanical …

Prevent Caking of Bulk Solids. Understanding the mechanisms behind caking, identifying key process variables and product specifications, and testing samples to predict the increase in cohesive strength of a powder over time are key to preventing and solving caking problems. Caking occurs when powders, such as detergents, fertilizers, food ...

Disadvantages of caking Caking of fertilizers or pesticides is an important problem for both the manufacturers and the users. Manufacturers must recycle the caked product to the process which results with and extra cost and end-users may have difficulties during the application of the fertilizer to the soil. Appropriate anti-caking agents should:

Caking in fertilisers. Between production and use in soil, fertilisers may need to be stored for long periods, and it is essential they remain free-flowing during this time. ... Therefore, we would advise if any firm caked1 lumps of cargo are observed at any point during the loading process, a protest is made and the master considers clausing ...
