(Page 1) The propensity for fine solid materials to cake can lead to flow problems that will adversely affect processes. When material caking disrupts gravity flow, a range of flow aid approaches are available to solve a variety of flow issues. This article discusses the operation of passive and active flow aids, as well as considerations for …

Consequences of Caking. Fertilizer caking makes each subsequent step in the fertilizer lifecycle more difficult and less efficient. In handling and transportation, caked fertilizer is difficult to load and unload and often exhibits a difficult flowability, which can cause process flow issues, increase labor costs, and even clog equipment.

Most fertilizers have some tendency to form agglomerates (caking) during storage. This caking is usually effected by: chemical composition, particle structure, moisture content hygroscopic properties, mechanical strength, product temperature, storage time and pressure.The aim of this study is to provide fundamental information on the …

The caking fertilizer, in the view of the peasants, it is the fake fertilizer with bad appearance, so many dealers have to arrange the workers to beat, which is time-consuming and laborious. The reason for the fertilizer caking 1.First of all, from the raw materials to analyze, the main reason is that the raw material is easy to dissolve.

Another challenge with maintaining fertilizer quality is when fertilizers are combined into NPK blends because each fertilizer has a different CRH and caking propensity. Some fertilizers can have limited or no compatibility (e.g. urea and triple super phosphate) with others for safety and chemical reasons [11]. Little data is available on …

In this work, a new anti-caking agent has been developed to cope with the granular fertilizer caking problem and improve their physical quality. First of all, thanks to the screening design of Plackett-Burman, the effect of seven anti-caking components on the phosphate fertilizer caking trend was evaluated only by eight trials.
