The design of the organic fertilizer production line aims to efficiently produce high-quality organic fertilizers from organic waste, which involves multiple processes and requires a series of specialized mechanical equipment. The following is a list of the main equipment typically included in organic fertilizer production lines:
1. Raw material crushing equipment
Including hammer crushers, roller crushers, or chain crushers, used to break large organic waste (such as straw, tree branches, etc.) into smaller fragments for subsequent processing.
2. Sorting and screening equipment
By using equipment such as vibrating screens and drum screens, non organic impurities such as stones and metals are removed from raw materials to ensure their purity and improve the quality of finished fertilizers.
3. Fermentation equipment
After crushing and screening, organic waste is sent to fermentation tanks or composting bins for anaerobic or aerobic fermentation. The fermentation turning machine or fermentation tunnel plays a key role in this process, promoting uniform fermentation of raw materials, accelerating the decomposition of organic matter, and killing harmful bacteria and viruses.
4. Drying equipment
The organic materials that have been fermented may contain high levels of moisture. Using a rotary drum dryer or fluidized bed dryer can remove excess moisture, which is beneficial for subsequent granulation and storage.
5. Granulation equipment
Granulator is a key equipment for turning dried organic materials into granular fertilizers. Common types of organic fertilizer granulators include disc granulators, extrusion granulators, and flat press granulators, which are suitable for different raw material characteristics and product requirements.
6. Cooling equipment
After granulation, the temperature of the fertilizer is relatively high, and a cooling machine (such as a fluidized bed cooling machine) needs to be used to quickly cool it down, avoiding the loss of nutrients at high temperatures, and also facilitating the next step of packaging and storage.
7. Screening equipment
Use the screening machine again to grade the cooled particles, remove unqualified small particles or powders, and ensure the consistency of the product.
8. Packaging equipment
Finally, use automatic or semi-automatic packaging machines to quantitatively package finished organic fertilizers for easy transportation and sales.
9. Auxiliary equipment
In addition to the main equipment mentioned above, a complete organic fertilizer production line also requires supporting conveying equipment (such as screw conveyors, belt conveyors), mixing equipment (for adding additional nutrients), and automated control systems to monitor and adjust various parameters of the production process, ensuring production efficiency and product quality.
The above equipment constitutes the basic configuration of an organic fertilizer production line, and the specific model selection will vary depending on factors such as raw material types, production scale, and product quality standards. Through careful design and reasonable configuration, the organic fertilizer production line can effectively convert organic waste into high value-added environmentally friendly fertilizers, promoting sustainable agricultural development.
