Working Process of New Type Organic Fertilizer Production Line
1. Fermentation: Organic materials fermentation process is important in the production. The temperature of the materials should be controlled carefully to prevent the temperature being too high to inhibit the activity of microbes and enzymes. Self-propelled compost turner and hydraulic compost turner are widely used to turn and mix the compost and accelerate the fermentation.
2. Crushing: After the fermentation process, the compost lump materials should be ground by crushing machine. Customers can choose semi-wet materials crusher, chain crusher or cage crusher at will. We recommend semi-wet materials crusher here.
3. Mixing: Use horizontal mixer or vertical mixer in this process to mix the materials and additives evenly. The additives can be added according to the nutrition requirements of different crops.

4. Drying: Before granulating, if the moisture of raw materials is more than 25%, the raw materials should be dried by rotary drum drying machine with a certain degree of humidity and particle size, as the moisture should be less than 25%.
5. Granulating: Use new type organic fertilizer pellet mill to granulate the raw materials into pellets, which can protect the microbial flora and the survival rate is more than 90%. Adjust the hole diameters of dies according the materials to achieve the optimal pelletizing results.
6. Drying: In the production of organic fertilizer, the pellets need to be dried at low temperature as the moisture is about 15%-20% and generally exceeding targets.
7. Cooling: The dried products enter into the cooling machine through a belt conveyor. The cooling machine uses cool gas to cool hot products and make full use of the exhaust heat.
8. Screening: we provide high-quality and good-performance rotary drum screening machine which is used for separating the returned materials and the finished products. The returned materials will go back to fertilizer crusher for further process, while the finished products are conveyed to fertilizer coating machine, or directly transported to automatic fertilizer packager.
9. Packaging: The finished products enter into the packing machine through the belt conveyor. The fertilizer packaging machine package finishes product quantitatively and automatically. Through creative thinking, more new technologies are added and applied in our packaging process, which makes the packager own both essential function and some specific properties which exactly satisfy the particular demands of different commodity and special environmental conditions.
