The processing of granular organic fertilizer mainly requires two steps, namely, the pre-fermentation treatment part and the deep processing and granulation part.
Fermentation section
Composting fermentation is to use the oxidative decomposition ability of natural microorganisms to controllably promote the biochemical degradation of degradable organic matter in materials under certain temperature, humidity and Ph value, and form stable humus. The control counter of the trough turning and throwing machine realizes automation and comprehensiveness, not only can complete manual operation, but also has a high level of automation.
For example, the nutritional value contained in chicken manure is higher than that of poultry manure, which can provide sufficient nutrients for soil and crops, and is a high-quality fertilizer. When chicken manure is processed into organic fertilizer, fermentation is a very important step. After the compost raw materials are transported to the stockyard, the moisture content and carbon-nitrogen ratio of the compost are roughly adjusted through the mixing device according to the composition of the raw materials. After the mixed raw materials are mixed into a fermentation pile, the pile should be turned over with oxygen for aerobic fermentation.
Granulation Processing Section
The fermented material is crushed and screened. After the undersize is granulated, it is sent to the dryer and then cooled. Finally, they are packed and sorted into storage. The unqualified sieve material is returned to the crushing process for reuse.
The entire organic fertilizer production process specifically includes physical dehydration→mixing (bacteria mixed in proportion + fresh livestock and poultry manure + crop straw crushing), fermentation, crushing, granulation, drying, cooling, sieving, finished product, packaging, and storage. Common organic fertilizer granulators include: npk fertilizer granulator, drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator machine, ring die granulator, each granulator has its own production characteristics, and the fertilizer granulator machine price varies.
