Compound fertilizer production line is widely applied to produce compound fertilizer and the capacity ranges from 5000-200,000 tons/year. It can granulate NPK, NP, ANP, DAP, MAP, CAN, SSP and other materials into compound fertilizer particles in one processing line. This equipment is specially used for manufacturing compound fertilizers with different concentrations and types, such as organic fertilizers, inorganic fertilizers, biological fertilizers and magnetic fertilizers, etc. It is mainly used for producing spherical particles with a diameter ranging from 1mm to 3mm.
Working Process of NPK Organic Fertilizer Granules Making Machine Production Line
Urea npk fertilizer production plant includes crusher, mixer, granulator, dryer, cooler, screening machine, packing machine,belt conveyor and other accessories,etc.
1.Vertical Chain Crusher
Put different raw materials into the vertical chain crusher. The raw materials will be crushed into small particles, so that they can meet the needs of the granulating process.
2.Disc Mixer
After crushing, they will be sent into the disc mixer, in which the raw materials will be uniformly blended. The lining of the pan is made of polypropylene or stainless steel sheet, which helps improve the working efficiency as well as the production quality.
3.Granulator
The granulating process is the most important part of the whole production line. Compound fertilizer production line mainly uses double roller granulator and rotary drum granulator. You can tell us your raw materials, our technicians will suggest you the best granulator accordingly.
4.Rotary Drum Dryer
During the drying process, the water contents of granulated particles will be dried, so that the particles will be harder and easier to store. The whole body is sealed, in which the materials will be contacted with the hot air with the continuous rotation of the drum.
5.Rotary Drum Cooler
After the drying process, the temperature of the particles is a little high, so they need to be cooled before the packing process. The cooler adopts the most advanced cooling technology in the world and makes the temperature of the particles is higher than the room temperature for 3 to 5 degrees Celsius.
6.Rotary Drum Screening Machine
After entering the rotary drum screening machine, the qualified particles will be sent into the coating machine, while the unqualified particles will be selected and then sent into the vertical chain crusher to be granulated again.
7.Rotary Fertilizer Coating Machine
The qualified particles will be coated by fertilizer coating machine, which will beautify the particles and strengthen their hardness at the same time. The fertilizer coating machine can prevent the caking of the fertilizer particles effectively.
8.Fertilizer Packaging Machine
After the particles are coated, they will be packed by the packing machine. The fertilizer packing machine is highly automatic, which makes the packing process more efficient and accurate.
