The equipment required for a bio-organic fertilizer production line with an annual output of 10,000 to 200,000 tons will vary depending on the production scale, raw material characteristics, production process and degree of automation.But generally speaking, this type of production line roughly includes the following core equipment categories:
1. Pretreatment equipment.Turning machine: used for fermentation and turning of materials, especially suitable for large-scale organic fertilizer fermentation, which can efficiently turn materials and improve fermentation efficiency.
Pulverizer: crush the fermented materials to meet certain particle size requirements for subsequent processing. The choice of pulverizer
should be determined according to the hardness and humidity of the material.
2. Mixing and stirring equipment.Mixer: used to mix the crushed materials with additives (such as inorganic fertilizers such as nitrogen, phosphorus, potassium, etc.) in a certain proportion to ensure stable product quality.
3. Granulation equipment.Granulator: According to the specific needs of the bio-organic fertilizer production line, granular organic fertilizer may be produced by extrusion granulation, disc drum double-stage granulation, etc. The granulator is one of the key equipment of the production line, and its performance directly affects the particle quality and output of the product.

4. Drying and cooling equipment.Dryer: used to remove excess moisture from the material after granulation so that the product reaches the specified moisture content standard. The choice of dryer needs to be determined according to the characteristics and output of the material.
Cooler: Cool the dried particles to prevent the high-temperature particles from deteriorating during storage and transportation.
5. Screening and packaging equipment.Screening machine: Screen the particles after drying and cooling to remove unqualified large and small particles to ensure uniform particle size of the product.
Packaging machine: Package the qualified particles after screening for easy storage and transportation. The packaging machine should have functions such as automatic weighing and sealing to improve production efficiency and product quality.
6. Conveying and storage equipment.Conveyor: used for material transportation between processes, reducing manual handling costs and improving production efficiency.
Storage equipment: such as fermentation tanks, silos, etc., used to store raw materials and semi-finished products to ensure the continuous and stable operation of the production line.
7. Other auxiliary equipment.Dust removal equipment: used to handle dust generated during the production process to protect the environment and employee health.
Control system: Automated control of the entire bio-organic fertilizer production line to achieve intelligent and efficient production process.
