The raw materials for making organic fertilizer are very diverse, such as various livestock and poultry manures, urban sludge, and plant and animal residues. These raw materials are rich in organic matter, nitrogen, phosphorus, potassium and other nutrients that provide essential nutrients for crop growth, and the purchase price is low.

The working principle of the organic fertilizer production line:

The processing of organic fertilizer mainly involves raw material collection, followed by crushing and mixing. Then, the raw materials are proportioned according to the required formula, and the moisture content and carbon-nitrogen ratio are adjusted before starting the fermentation process.

Fermentation compost turning machine:It assists in turning the raw materials during the fermentation process, providing sufficient oxygen and controlling the temperature to ensure uniform and thorough fermentation.

Fertilizer mixer:The fermented materials have inconsistent sizes and states. A semi-wet material crusher can be used to finely crush them.

Fertilizer granulator:The crushed materials are processed into uniformly sized organic fertilizer granules through an organic fertilizer granulator.

Fertilizer cooler:The granulated organic fertilizer still contains about 30% moisture. To increase its strength, the granules need to be cooled. This also makes it easier for storage and transportation in the later stage.

Fertilizer screener machine :After granulation, there will be a small amount of substandard granules, some too large and some too small. Fertilizer screener machine is used to separate them. The oversized ones are returned to the fertilizer crusher, and the undersized ones are returned to the fertilizer granulator for re-granulation. The qualified granules will flow into the automatic packager.

Fertilizer packaging machine:The finished organic fertilizer granules are packaged using an automatic packager, completing the entire processing process.

However, it should be noted that the above configuration is a conventional organic fertilizer production line configuration and may not be suitable for all situations. In actual production applications, different producers may have different requirements in terms of site, raw materials, and other aspects, and adjustments need to be made according to actual needs.
