Caking Protection

LignoStar, the Anti-Caking agents Supplier

As an exclusive distribution partner of Novochem, LignoStar offers specialized Caking Protection coatings and additives for fertilizer blenders from the NovoFlow product range.

Most fertilizers have some tendency to form lumps or agglomerates during storage. The reason for caking in fertilizers is most often attributed due to the formation of salt bridges and/or capillary adhesion. Fertilizer caking can be influenced by a number of factors, such as chemical composition, moisture content, particle structure, mechanical strength, hygroscopic properties, product temperature, ambient conditions, storage time, and storage pressure. The various techniques of reducing or eliminating caking in fertilizers basically involve process control, storage/packaging conditions, and the addition of anti-caking agents.

NovoFlow Caking Protection

NovoFlow products are available for each type of production process, such as blending, granulation, crystallization, and for each type of fertilizer. The technical specialists of LignoStar and Novochem are available for the application advice of anti-caking agents for specific fertilizer properties, production processes, storage conditions, and climatic conditions.

NovoFlow anti-caking agents are available for each type of production processes, such as blending, prilling, granulation, and crystallization, and for each type of fertilizer:

Ammonium Nitrate (AN)Ammonium SulfatePotassium Nitrate  
Calcium Ammonium Nitrate (CAN)Ammonium Phosphate  Potassium Nitrite  
NPK/NK/PK/NPPotassium Chloride  Blends  
Urea  Potassium Sulfate  Sodium salts  
Calcium Carbonate / ChalkMagnesium Carbonate / Dolomite   

All NovoFlow anti-caking products should be sprayed on the prills or granules using a metering pump. It is strongly advised to use spray nozzles for good distribution of the coating agents on the fertilizer prills or granules.

Dosage and method of application of NovoFlow

Usually, 400 to 5000 grams of NovoFlow per ton fertilizer will be sufficient to prevent both moisture absorption and caking. However, operating variables determine the exact amount to be employed. The optimum dosage for each fertilizer grade can only be determined by testing under plant conditions. NOVOFLOW can be sprayed over the prills or granules by means of a metering pump with a spray nozzle device. After spraying, ensure a good distribution of the product on the surface of the fertilizer particles.
