The Disc Granulation Process for organic fertilizer made from livestock and poultry manure features a short production line, simple structure, low investment, and easy operation. It is highly suitable for small and medium-sized enterprises.
The size of organic fertilizer granules is determined by the inclination angle and rotation speed of the disc granulator, both of which are adjustable. This ensures a wide control range for particle size, high adaptability, and a superior balling rate. The operation is intuitive, allowing real-time monitoring and timely adjustments during production.
Step-by-Step Production Process
Raw Material Loading: Transport the processed manure directly to the Raw Material Hopper (or Raw Material Mixer).
Granulation: The manure is fed into the Disc Feeder, then evenly added to the rotating Disc Granulator. Liquid components or water are sprayed onto the material via a distributor to reach the required moisture level. The friction and centrifugal force from the rotating disc cause the powder to roll, rub, and squeeze, gradually forming granules. Due to weight differences, larger granules are discharged once gravity overcomes friction, while smaller particles remain in the disc to continue growing.
Drying: Materials are conveyed to the Organic Fertilizer Dryer, where heat exchange occurs with hot air from the Hot Blast Stove.
Hot Screening: Particles are sorted in the Hot Screening Machine. Fine particles are returned to the disc feeder to serve as “cores” for new granules.
Cooling: The fertilizer is sent to the Cooling Machine, cooled by natural or forced air.
Finished Product Screening: Materials go through the Product Screener. Oversized granules are crushed by a Crusher (such as a Cage Mill) and returned to the disc feeder for re-granulation.
Coating: Qualified granules are conveyed to the Coating Machine for surface treatment.
Packaging: Finished products are sent to the Automatic Packing Scale for weighing, bagging, and warehousing.
Dust Control: Exhaust and dust from drying, cooling, and the workshop undergo a three-stage treatment (Cyclone Dust Collector, Labyrinth Dust Chamber, and Wet Scrubber) to meet environmental emission standards.
