Description

Technical Field

[0001] This invention belongs to the technical field of fertilizer production machinery and equipment, specifically relating to an energy-saving and environmentally friendly compound fertilizer granulator. Background Technology

[0002] In agricultural production, the use of chemical fertilizers is crucial and a key factor in increasing grain production. However, currently, single fertilizers cannot meet the needs of increased crop yields. Different crops require different production environments, so their fertilizer requirements also differ. When planting, most farmers buy different types of fertilizers to achieve good fertilization results and then mix them based on experience. This method is inefficient and produces poor mixing results: all the fertilizers are poured into a mixing pan according to a rough ratio and then stirred with a tool. This method is prone to uneven mixing, affecting the fertilization effect, and is also labor-intensive and unsuitable for large-scale fertilizer mixing.

[0003] Therefore, how to provide a compound fertilizer granulator that can mix multiple fertilizers is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a compound fertilizer granulator that can mix multiple fertilizers, using one granular fertilizer as the main component and multiple powdered fertilizers as auxiliary components to form compound fertilizer granules.
