Natural fertilizer mixtures whose production processes have been completed are in the form of fine powder in the first version. In this case, it is almost impossible to give fertilizer homogeneously to the soil.

Since both the wind swing and the viscosity are very low in this state and will have a negative impact on the health of working people due to flying, this powdered mixture should be used after being converted to solid particles of 1 to 4 mm.

The process of converting the fertilizer, which was initially in the form of powder, into solid, but easily disintegrated particles when thrown into the soil, is called the GRANULATION PROCESS.

Granulation process: wet system (pelletizing) and DRY GRANULATION is done with two systems called.

In the wet system: the product is firstly made into fluid suspension or viscous paste with water and other binders.

The fluid suspended material is disintegrated into granules by spraying downward from high towers with hot air blown beneath. The particles falling downwards are collected under the tower by drying under the influence of the incoming hot air. This system is often called the Spray Dryer granulation system.

In the other, the material which is made into a viscous dough is pressed by means of extruder and cut into pellets of desired dimensions, then dried and evaporated its water with the help of hot air in fluid bed dryers or various types of conveyor ovens.

In both cases, electricity and natural gas are consumed at a very high rate both during the preparation of the material and during the drying of the particles.

In addition, due to the fact that the fertilizer granules produced by this system have a soft structure after being dried, the majority of them are broken down during packaging and shipment and they are turned into powder form.
