The Methods and Steps of Turning Cow Dung to Organic Fertilizer
Cow dung is regard as waste from the point of cattle farm. Whether it can be used for secondary development of cow dung and making full use has become the focus of attention. However, this problem is not difficult at present. With the emergence of various advocacy and encouragement policies for the development of the organic fertilizer industry by the state and local governments, the timing of the large-scale and industrialized development of organic manure for cattle manure has matured.
What kind of organic fertilizer equipment do you need to turn cow manure, chicken manure and sheep manure into organic fertilizer? Let’s Shunxin Machinery tell you:
The first step: fermentation
Collect the cow dung cow urine, mix it with hay and rotten silage to make it compost. In the fermentation, the use of a turn-over machine allows the cow dung to be fully fermented, and this can only be done in a timely and even turn. Some places are very dry now, and some places are very wet, which affects the quality of the fermentation.
The second step: crushing and mixing
Use the batching bin to mix the materials after composting, and inorganic fertilizers such as N, P, K, and other additives, through a material pulverizer and a horizontal mixer for crushing, proportioning and mixing.
The third step: granulation
The material is granulated using a new type organic fertilizer granulator.
Step four: Screening and material returning system
The pellets output from the granulation molding system have a certain difference in particle size and require sieving and grading. The rotary sifter selected requires less vibration, low noise, convenient screen change, and is equipped with a screen cleaning device. It is recommended to equip the automatic feeding system to screen out unqualified large and small granular materials, which are transported out through the belt hoist, re-pulverized and sent to the granulator for further granulation, which helps to improve the continuous operation capacity of the production line.
Step 5: Drying
The organic fertilizer dryer is used to further remove water of the granules after sieving to meet the standard requirements for the moisture content of the organic fertilizer.
Step 6: Cooling
Cool the pellets with a cooling machine which helps to preserve the quality of the granules.
Step 7: Packaging
The cooled particulate material is transported through the bucket elevator into the finished product bin. Granular materials are quantitatively weighed and packaged by automatic packing.
