The process of processing livestock manure into organic fertilizer:
The first step: fermentation
Collect livestock manure, mix it with hay and decaying silage, etc. to make compost, and let it ferment. In the fermentation process, the pile turning machine is used to fully ferment the livestock manure, which can only be achieved by turning the pile in time and evenly. Now some places are very dry and some places are very wet, which will affect the quality of fermentation.
The second step: the ingredients are crushed and mixed
Use the batching bin to pulverize, proportion and mix the composted materials, N, P, K and other inorganic fertilizers, and other additives and other raw materials in a certain proportion through a material crusher machine and a horizontal mixer machine.
The third step: granulation
A new type of organic fertilizer granulator is used to granulate the material.
Step 4: Screening and material return system
The granular materials output from the granulation forming system have certain differences in particle size and need to be sieved and classified. The selected rotary screening machine requires low vibration, low noise, convenient screen change, and is equipped with a screen surface cleaning device. It is recommended to be equipped with an automatic material return system to screen unqualified large and small particles, convey them through a belt elevator, and send them to the pelletizer to continue pelletizing after being crushed again, which helps to improve the continuous operation capacity of the production line.
Step 5: Drying
Use an organic fertilizer drying machine to further remove water from the sieved particles to meet the standard requirement of organic fertilizer moisture content.
Step 6: Cool down
Cooling the granular materials with a cooler helps the storage and quality of the granules.
Step 7: Packaging
