Economic Organic Fertilizer Disc Granulation Production LinePosted by Fertilizer Granulator on May 30th, 2019 Organic fertilizer disc granulation production line is widely used in farmland, fruit trees, flowers, landscape greening, soil improvement and other fields. It is suitable for large and medium-sized enterprises, with short production process, simple structure, less investment and easy operation. Due to different materials, different site conditions and different product objectives, fertilizer production equipment and production line layout are different.
Raw material pretreatment
Fermentation is the first step after material collection. It is necessary to use the compost turner machine to dump the material to accelerate the fermentation speed. After the fermentation, the material is crushed into powder, and then processed in the organic fertilizer granulation production line. Here is a brief introduction of a mature organic fertilizer disc granulation production line designed by our factory for many years.
1.Batching
This batching machine is mainly suitable for 3 to 8 kinds of the material feeding , burdening and mixing , which use the computer for automatic control scale and with pneumatic door for main quantitative feeding control , material after mixing with a belt machine automatically sent out. 2.Crushing Chain Crusher: The machine has compact structure, low power consumption and convenient maintenance. It is also suitable for crushing compound fertilizer raw materials. 3.Mixing Vertical Disc Mixer: The mixer machine is mainly used for mixing raw material in batches, material can be fully mixed. The mixer adopts the cycloidal pin gear speed reducer, which has the advantages of compact structure, easy operation, unloading transportation is convenient. 4.Granulating
Disc Granulator: This granulator design is thicker, heavier and more stable, not need to be fixed by anchor bolts. The rotating disc and its edge exert friction and centrifugal action on the material, which causes the powder particles to knead and extrude with each other and gradually agglomerate into spheres. Because of the difference of particle mass, the gravity and centrifugal action are also different. When the gravity and centrifugal action increase enough to overcome the friction between particles, they will be thrown out of the disk, and smaller particles will remain in the disk and continue to accumulate fine particles.
 5.Drying and cooling
Rotary Drum Dryer: After granulating, granules humidity is high, need drying with dryer machine. The heat source of the drum dryer comes from the Hot Air Stove and adopts the downstream heating mode.
Rotary Cooler: After drying, the granules need cooling down to noraml temperature. 6.Screening Rotary Screener Machine: There are some non-uniform particles, after sieving get the appropriate granules that we need, the small diameter particle can be screened down for twice processing, the bigger granules go to the crusher machine again. Screening twice to ensure get the proper size of particles 7.Coating Coating machine: Coating on the surface of fertilizer particles, can effectively prevent the organic fertilizer caking. 8.Packing Packing Machine:Automatic quantitative packaging of powder and granules, suitable for flour, starch, feed, food, chemical industry, light industry, building materials industries. Organic fertilizer disc granulation production line is one of the treatments for organic fertilizer granulation. The specific investment and construction should be adjusted according to the actual situation. Like it? Share it! More by this author |
