Process flow of 15-20 t/d Organic fertilizer production line:
1. The production process of Organic fertilizer granulator is mainly to screen, magnetic separation, granulation and drying the organic waste with a moisture content of about 30% -35% after fermentation and decomposition to prepare round Organic fertilizer. Adding functional bacteria can produce biological Manure, and adding nitrogen, phosphorus and potassium (the total nutrient content is less than 15%) can produce organic and inorganic fertilizer.
2. After magnetic separation and screening of the fermented organic waste, it is measured and batched with the raw materials of binders and other components that need to be compatible according to the ratio requirements. It is lifted by a bucket elevator to a multi-dimensional high-efficiency mixer for rapid mixing. The fully mixed material slides out into the mixing silo, and is uniformly and continuously fed into the extrusion granulator by a disc feeder to form columnar particles;
3. The particles are polished and shaped into spherical particles by the round particle polishing and shaping machine, and sent to the drying, cooling, Organic fertilizer screening machine (three in one model) by the belt conveyor. The particles are dried at low temperature and large air volume in the front section of the drying and cooling screening machine (≤ 65 ℃), and then enter the cooling section for air cooling. The fully cooled materials enter the screen installed at the end of the cylinder, and the screened finished particles are transported to the finished product silo by the elevator, and then measured by the packaging system Packaging and warehousing;
4. The screened large particles are crushed and then returned to the mixed granulation system; The small particles screened out (basically without powder) can be made into small packaging and sold directly..jpg)
Process characteristics of 15-20 t/d Organic fertilizer production line
（1） The new process of extrusion granulation and polishing can be used to produce “spherical” pure Manure, organic and inorganic fertilizer, and biological Manure. The process flow is short, the operation cost is low, the Manure produced is uniform and round, the surface is smooth, the compressive strength is high, the fluidity is good, the survival rate of microbial bacteria is>90%, the granulation rate is 85-95%, and the particle diameter is 3.5-4 mm.
（2） The new process of extrusion granulation and polishing and shaping has strong adaptability to raw materials, which can completely solve key technical problems that traditional granulation processes such as discs or drums are difficult to solve:
1. The fermented organic materials can be directly used for granulation without the need for pre drying or crushing treatment. Traditional granulation processes such as disc or drum have high requirements for raw material fineness, which means that over 80% of the material should have a fineness of over 80 mesh. Therefore, it is necessary to crush it. Due to the high moisture content of the fermented organic material, it needs to be dried to below 13% moisture before crushing to meet the crushing conditions, which requires high equipment investment and high operating costs.
2. It can increase the addition amount of organic materials to over 95%. Traditional granulation processes such as disc or rotary drum use more than 80 mesh organic materials and add binders, and the maximum amount of organic raw materials is 30-40%. Therefore, to produce spherical Organic fertilizer with high content or pure organic matter, traditional granulation processes cannot be achieved.
How much is the manufacturer’s quotation for a full set of 3000-5000t/a Organic fertilizer production line? There is no complete answer to this question, because different equipment configuration schemes, different production line process designs, and different output demands of Manure production lines with an annual output of 3000-5000 tons will require different funds. The specific quotation of Organic fertilizer production lines with an annual output of 3000-5000 tons depends on the actual configuration. However, it can be determined that the configuration is more scientific, more reasonable and more suitable for actual production, and the price investment of equipment will be more cost-effective. Generally, the manufacturer’s quotation for a full set of Organic fertilizer production lines with an annual output of 3000-5000 tons will be in the range of 80000-50000.
