The organic fertilizer equipment manufacturer tells you how to deal with the caking of fertilizer?

How do we avoid caking problems in fertilizer processing, storage and transportation? The caking problem is related to the fertilizer material, humidity, temperature, external pressure and storage time. We will briefly introduce these problems here.

Materials commonly used in the production of fertilizers are ammonium salt, phosphate, trace element salt, potassium salt, etc., which contain crystalline water and tend to agglomerate due to moisture absorption. Such as phosphate is easy to agglomerate, phosphate and trace elements meet, easy to agglomerate and become insoluble in water substances, urea encountered trace element salt is easy to precipitate out of water and agglomerate, mainly urea replacement of trace element salt crystal water and become paste, and then agglomerate. Fertilizer production is generally not closed production, in the production process, the greater the air humidity, the fertilizer is more likely to absorb moisture and caking, dry weather or drying raw materials, fertilizer is not easy to caking.

The higher room temperature, the better dissolution. Usually the raw material dissolves in its own crystalline water and causes caking. When the nitrogen is hotter, the water evaporates, and it's harder to agglomerate, the temperature is usually above 50 degrees Celsius, and we usually have to heat it to get that temperature.

The greater the pressure on fertilizer, the easier the contact between crystals, much easier for caking; the less the pressure, the less likely to agglomerate.

The longer fertilizer is placed, the easier it is to caking, and shorten the time, the less likely to caking.
