The organic fertilizer pellet production line project is a process that uses organic waste fermented by microorganisms to produce organic fertilizer through granulation.

Process flow of a daily production line for 500 tons of straw granular organic fertilizer

1. Mainly, raw materials containing organic matter (such as sheep manure, pig manure, sludge, chicken manure, duck manure, cow manure) with a moisture content of about 70% are mixed with crushed organic waste (such as straw, corn straw and branches, mushroom residue) and then added with a biological fermentation agent for fermentation.

2. Use a forklift to load the mixed (sheep manure, pig manure, sludge, chicken manure, duck manure, cow manure) and other plant straw into a fermentation and maturation tank, and evenly add fermentation bacteria for maturation.

3. Fermented raw materials can be directly transported to the organic fertilizer crusher for crushing through an automatic material system using a belt conveyor. The crushed materials can be directly transported to the screening machine using a belt conveyor. The screening machine screens out impurities that are not fully decomposed or crushed, and then uses a belt conveyor to transport them to the waste disposal site for processing;

4. After fermentation and crushing, the raw materials are accurately proportioned (bentonite, humic acid) with a forklift into the automatic batching bin and other raw materials (adding nitrogen, phosphorus, and potassium with a total nutrient content of less than 25%) to produce organic and inorganic fertilizer compound fertilizers. After proportioning, they are quickly and evenly stirred by a mixer.

5. It enters the organic fertilizer granulator through a belt conveyor, and a small amount of water is added to the inlet for granulation. The particles formed by the granulator are then transported by the belt conveyor to the rounding machine for shaping

6. After drying and cooling, the particles are sieved by a belt conveyor through a powder screening machine for final product screening. The particles that do not meet the requirements are transported to the waste crusher by a (finished particle 2-4mm) belt conveyor for thorough crushing, and then returned to the granulator for further granulation by the return material belt conveyor.

7. After sieving the powder, the particles are coated by a coating machine and can be added (functional bacteria can produce bio organic fertilizers)

8. After adding functional bacteria to the coating machine, the particles are transported by a belt conveyor to the second screening machine for particle size screening. The particles (2mm and 4mm) can be separated and packaged separately, making them more beautiful,
