How to choose pig manure organic fertilizer equipment for pig farms?
How a pig farm chooses a manure resource utilization mode mainly depends on the characteristics of the regional resources, environment, climate, local support and the size of the pig farm. It is better to make organic fertilizer from pig manure. And there are two two steps to make pig manure organic fertilizer: the fermentation part and the deep-processing granulation part.
Fermentation is a preliminary process for the production of organic fertilizer. Common types of fermentation equipment include groove type compost turner, moving type compost turner, fermentation cylinder and so on.
The deep-processing granulation part is: the fermented pig manure are translated into a semi-wet material pulverizer for pulverization. Then, the elements such as nitrogen, phosphorus and potassium are added to make the mineral elements contained in the required standard, and a mixer is used for stirring. After mixing well, they can be made into granules by the new type organic fertilizer granulator. After the granules come out, they are dried and sieved by a sieving machine. The qualified products are packaged, and the unqualified products are returned to the granulator for granulation.
