How to use the organic fertilizer production line for manure recycling
2022-09-17
With the increase of large-scale livestock and poultry farms, the total amount of manure put on farmland exceeds the capacity of farmland, and the random accumulation of manure that cannot find a way out has caused serious environmental pollution, which has attracted the attention of the government. The regulations stipulate that large-scale livestock and poultry farms must have facilities for the storage, treatment and utilization of manure and sewage.
The treatment of livestock and poultry manure is mainly carried out in accordance with the principle of "resource utilization", and the comprehensive utilization of livestock and poultry manure is carried out by using the organic fertilizer npk manufacturing process. Livestock and poultry manure has resource attributes and can be returned to the field to make organic fertilizers. The fertilizer utilization of livestock and poultry manure organic fertilizer equipment can further increase the content of soil organic matter, improve the quality of agricultural products, and ensure the sustainable production capacity of farmland.
In the organic fertilizer npk fertilizer production line, after the pretreated livestock and poultry manure enters the organic fertilizer stirring and fermenting device for fermentation, an appropriate amount of nitrogen, phosphorus, potassium and other elements are added in a certain proportion to make the trace elements contained in the organic fertilizer production standard. And then go through the processing technology of stirring, pulverizing, forming, granulating, drying, packaging and so on. Granulation is an important link in the production of granular organic fertilizer. Extrusion granulation is simple and practical. After the compost after fermentation is adjusted to a moisture content of 20% to 30%, it can be directly entered into the granulator and extruded into cylindrical granules. The press granulator, the double roller granulator and the disc granulator are relatively small, with low production capacity and relatively cheap price, generally 30,000 to 50,000 yuan; the drum granulator is large in size and generally has a length of At about 10m, the production capacity is large, the smallest can reach 3t•h-1, and the price is relatively expensive, generally around 100,000 yuan.
