Collect cow dung and cow urine, mix it with hay and rotten silage, etc. to make compost and let it ferment. In the fermentation process, the fermentation compost turning machine is used to fully ferment the cow dung, which can only be achieved by timely and even dumping. Now some places are very dry and some places are very wet, which will affect the quality of fermentation. https://www.fertilizerproductionprocess.com/fermentation-compost-turning-series/
2. Crushing and mixing of ingredients
The composted materials, inorganic fertilizers such as N, P, K, and other additives are crushed, proportioned and mixed by material crusher and horizontal mixer according to a certain proportion.
A new type of organic fertilizer granulator was used to granulate the materials. https://www.fertilizerproductionprocess.com/fermentation-compost-turning-series/
4. Screening and return material system
The particle size output from the organic fertilizer granulator has a certain difference and needs to be sieved and classified. The selected rotary screener machine requires low vibration, low noise, convenient screen change, and is equipped with a screen surface cleaning device. It is recommended to equip a return system: the unqualified granular materials that are screened out are conveyed by a belt elevator, re-pulverized and sent to the granulator to continue granulation, which helps to improve the continuous operation capacity of the production line.
Use an organic fertilizer drum drying machine to further remove moisture from the sieved particles to meet the standard requirements of organic fertilizer moisture content. https://www.fertilizerproductionprocess.com/fertilizer-dryer-cooler-coating/drum-dryer.html
Cooling the granular materials with a cooler helps the storage and quality of the granules.
The granular materials cooled by the organic fertilizer equipment are conveyed into the finished product warehouse through the bucket elevator. Granular materials can be quantitatively weighed and packaged through automatic packing scale.
