Compound fertilizer production line
process can usually be divided into: raw materials ingredients, raw materials, mixing, raw materials, granulation, particle drying, particle cooling, particle classification, finished coating, the final product packaging.
The equipment investment is small, quick, good economic returns. Complete sets of equipment flow layout compact, scientific and reasonable, advanced technology. Energy saving, no waste discharge, stable operation, easy operation and reliable maintenance. Raw material adaptability, suitable for compound fertilizer, medicine, chemicals, feed and other raw materials of granulation, product granulation rate is high. Can produce a variety of concentrations, a variety of types (including organic fertilizer, inorganic fertilizer, bio-fertilizer, magnetic fertilizer, etc.) compound fertilizer. Especially the scent, ammonium bicarbonate series of compound fertilizer granulation, to fill the domestic blank, ranking the leading domestic level.
1, raw materials Ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (ammonium phosphate, diammonium phosphate, calcium, calcium), potassium chloride (potassium sulfate) and other raw materials according to a certain proportion Market demand and local soil testing results).
2, raw material mixing: with a good mix of raw materials to improve the fertilizer evenly the average fertilizer content.
3, raw materials granulation: the mixing of raw materials into the granulator granulation (drum can be used drum machine, can also use extrusion granulator).
4, the particles drying: granulation machine made of particles into the dryer, the particles contained in the water drying, increase the particle strength, easy to save.
5, particle cooling: After drying the fertilizer particles temperature is too high, easy to agglomerate, after cooling, easy to bag storage, and transport.
6, the particle classification: the particles after cooling the classification, substandard particles by grinding to re-granulation, the qualified product screening out.
7, the finished film: the qualified product coating coating to increase the brightness and roundness of particles.
8, finished packaging: the film will be wrapped in the film bag is placed in a ventilated place to save.
