How to use poultry waste to make granular fertilizer?
Step 1: Fermentation
After collecting poultry waste and mixing it with hay, rotten silage, bacteria and so on, you need to make compost and then let it ferment. In the fermentation, the compost turner equipment is used to fully ferment the waste. If some places are very dry and others are very wet, it will affect the quality of fermentation.
Step 2: Crushing and mixing the ingredients
After mixing the composted materials, inorganic fertilizers like N, P, K and other raw materials in the batching bin, they will be crushed and mixed in a certain proportion by the new type vertical crusher and horizontal mixer.
Step 3: Granulating
In this step, there is a new type organic fertilizer granulator to granulate materials.
Step 4: Screening and recycling system
The granular material from the granulation molding system has a certain difference in size of pellets. Therefore, it needs to be sieved and classified.
Step 5: Drying
Through the rotary drum drying machine, the moisture are further removed from sieved pellets so that to meet the standard requirements of organic fertilizer moisture content.
Step 6: Cooling
The granular materials need to be cool by using the rotary drum cooling machine, which helps to keep the granules in storage and guaranteeing quality.
Step 7: Packaging
The granular materials cooled by the rotary drum cooling machine are transported into the finished product warehouse through the bucket elevator. Granular materials can be quantitatively weighed and packaged through single (double) bucket automatic packing scale.
