Description

Technical Field

[0001] The utility model relates to the technical field of extrusion granulation, in particular to a fertilizer extrusion granulator. Background Art

[0002] Granular fertilizer is an essential fertilizer for agricultural production. Granular fertilizer is typically made by mixing various fertilizer ingredients in a specific ratio based on plant growth needs, then extruding them into uniformly sized pellets. Existing granular fertilizers are mostly produced by directly extruding them using two rollers.

[0003] However, this extrusion method does not have a component that heats the roller. Although the roller will automatically heat up after a certain period of time, it is relatively cold when it is first started, making it difficult to form particles, and it is easy to produce powder or scatter directly. At the same time, on the one hand, some granular fertilizers tend to stay in the hemispherical holes and cannot fall off, resulting in low extrusion efficiency. On the other hand, the raw materials tend to adhere to the extrusion roller or the hemispherical holes, causing the extruded particles to become smaller and smaller. Utility Model Content
