There are many sources of nitrogen fertilizer, human feces, chicken, duck, goose feces, pig manure, and bean cakes are considered to be the best, nitrogen fertilizer sources some common phosphate fertilizer sources include chicken manure, bone meal, hair, animal hair, rice bran, rice washing water, fish innards, etc. Common potash fertilizer sources include grass and wood ash, charcoal residue, and banana peel.Raw materials are fermented and mixed to create fertilizer particles that can be stored and transported,roller extruding granulator is the key equipment of compound fertilizer granulation. It has the characteristics of advanced technology, reasonable design, compact structure, low energy consumption and matching with the corresponding equipment.
WORKING PRINCIPLE
The dry powder material is added to the top of the roller press granulator, and the rolls are rotated by reverse and constant speed, biting the material and forcibly compressing.
After the compression, the pressure of the material is lowered, and under the action of gravity and surface tension, it naturally escapes, and the crusher is broken and the granulator is granulated.
Finally, the screener is sieved and the qualified product is packaged. For the material under the powder screener, the returning system returns the fertilizer powder to the raw material bin for re-rolling.
The size of the pressing force of the dry roller granulator can be adjusted according to the requirements of the strength of the granules. Different press rolls can be used for materials of different volume shapes.

If the scale is gradually formed, the granulator combined with other NPK fertilizer production machines such as powder machines, mixers, transport machines, packaging machines, etc., can be grouped into a NPK fertilizer production line，Huaqiang Heavy Industry is a variety of fertilizer production line including all aspects of the machine, welcome to consult at any time
