Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, in particular to granulating equipment for fertilizer production. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. During the planting process of crops, fertilizers are often added to the soil to facilitate the growth of crops and increase yields.

[0003] At present, the corresponding granulation equipment is needed in the production process of fertilizers to make the fertilizers into granules. The granules increase the absorption rate. Granular fertilizers form a certain local fertility zone around the crop roots, which improves the fertilizer effect and makes the fertilizer easier to absorb. In addition, it is not easy to be blown away by the wind during the fertilization process.

The rotation of the spiral extrusion piece 264 will extrude the raw materials inside the extrusion barrel 261 and extrude the raw materials from the granulation hole 268. The rotation of the cutting knife 267 will take the extruded raw materials and cut them. Fertilizer particles are thereby formed. The manufactured fertilizer particles fall into the interior of the discharge chamber 2 and roll down from the discharge channel 3. During the rolling process, the hot air flow will reduce the rolling speed of the fertilizer particles. At the same time, the hot air flow will dry the fertilizer particles.
