Caking Control

Anticaking Agent For Fertilizers

Caking or agglomeration is a major concern for dry fertilizer production, handling, and application. Due to the hygroscopic nature of salts in freshly manufactured fertilizers, the granular masses tend to coalesce to form cakes that are difficult to separate. Further, the formation of fertilizer cakes tends to intensify by persistent storage. An appropriate anti-caking agent application works on the microscopic level to disrupt cake formation mechanisms to make fertilizer free-flowing.

The storage and handling of materials in bulk have elicited unique problems pertaining to cake formation and dust formation. In the fertilizer industry, this problem has elevated to a vast scale that causes waste and cost issues and has several potential environmental, safety, and health hazards associated with it. Dust particles of the several kinds of anticaking agents for fertilizers are usually small and light enough to be transported even by weak air currents. Some of the key reasons for caking in fertilizers are:

Fertilizer Granules:

Small granules are more easily to cake than large ones. If the granules of fertilizer are not uniform, or there are too many small particles, or the shape is not so round, In that case, the particle strength is low. The granules are prone to efflorescence or deformation under high pressure. The fine power largely reduces the contact area and causes caking.

Packing Temperature and Storage Temperature:

If the environment temperature during storage is too high, the critical relative humidity of compound fertilizer will decrease, and the fertilizer is easy to cake.

If packing and keeping the fertilizer in storage while the dried granules are not fully cooled, especially when the storage temperature is high, the internal water of the fertilizer will evaporate again. The hygroscopicity of the fertilizer causes the vapor around the granules/prills to condense immediately upon contact with the particles.
