What is the working principle of the pig manure organic fertilizer granulator for processing fertilizers

The pig manure organic fertilizer granulator usually adopts extrusion granulation technology, and its working principle is based on physical changes, mainly including the following steps:

Feeding system:

Pig manure is evenly fed into the working chamber of the organic fertilizer granulator through the feeding system.

The feeding system usually includes a storage bin and a conveying device to ensure continuous supply of pig manure to the interior of the granulator.

High pressure environment:

When pig manure enters the working chamber of the organic fertilizer granulator, it is subjected to high pressure.

There are one or more rotating spindles inside the granulator, which are equipped with a series of molds or pressure rollers.

Pig manure is gradually squeezed into granules by the rotation of the main shaft and the compression of the mold.

Granulation process:

Under the action of high pressure and friction, the surface of pig manure particles begins to harden, and as the material moves in the mold, the particles gradually increase in size.

Meanwhile, due to the moisture and adhesive inside pig manure, the binding force between particles is enhanced, forming a stable structure.

Molding and demolding:

When the particles reach a certain size and hardness, they will detach from the mold and form a complete granulation product.

These particles are then discharged from the granulator through the discharge port and enter the next processing stage.

Drying and cooling:

Freshly granulated particles may contain high levels of moisture and require a drying process to reduce their moisture content for better storage and transportation.

The dried particles may still need to be cooled to prevent quality issues caused by excessive temperature.

Screening and Grading:

Finally, the pelletized product is screened using screening equipment to remove unqualified particles and obtain organic fertilizer products that meet the standards.

The pig manure organic fertilizer granulator converts pig manure, a low value waste, into organic fertilizer particles with a certain shape and particle size through the above working principle, thereby improving its market value and utilization effect.
