Organic fertilizer granulator is a specialized equipment used for producing organic fertilizers. Its working principle mainly involves a series of process steps such as crushing, mixing, adjusting moisture content, and granulation of organic materials to produce granular organic fertilizer. The working principle of the organic fertilizer granulator will be introduced in detail below.

1、 Preparation of raw materials

The main raw materials required for organic fertilizer granulators are various organic waste, crop straw, livestock manure, etc. Before granulation, it is necessary to perform preliminary processing on the raw materials, including cleaning, screening, crushing, etc. This can ensure that the quality and particle size of the raw materials meet the requirements, to ensure the smooth progress of subsequent process steps.

2、 Mixing and regulating moisture

After preliminary processing, the raw materials need to be mixed and adjusted for moisture content. Mixing is the process of mixing different types of raw materials in a certain proportion to meet the standards for making organic fertilizers. Adjusting the moisture is to ensure that the humidity of the raw materials is appropriate, so that the subsequent granulation process can proceed.

3、 Granulation

Granulation is the main process step of organic fertilizer granulator. During the granulation process, it is necessary to press the mixed raw materials into granules through the mold of the granulator. The shape and size of the mold can be adjusted as needed. During the pressing process, cellulose and hemicellulose in the raw materials will be destroyed to facilitate subsequent microbial decomposition.

4、 Drying and Cooling

Producing granular organic fertilizer requires drying and cooling. During the drying process, organic fertilizer particles should be placed in a well ventilated area or dried using specialized drying equipment to reduce moisture content. During the cooling process, the dried organic fertilizer particles are cooled by a cooling device for subsequent packaging and storage.

The working principle of the organic fertilizer granulator is mainly to mix the raw materials, adjust the moisture content, and then go through a series of process steps such as granulation, drying, and cooling to make granular organic fertilizer. The application of this machine greatly improves the utilization rate of organic fertilizers and is also an environmentally friendly and energy-saving production method.
