On May 30, 2024, an Australian customer asked us: how to make bio fertilizer from cow dung? To make cow manure into bio fertilizer, the following steps are required: dehydration, fermentation, crushing, granulation, drying, cooling, and packaging. Under our communication, the customer chose the solution suitable for his biofertilizer manufacturing. If you have any questions, please contact us.
The solution of how to make bio fertilizer from cow dung
There are two ways to make bio fertilizers from cow dung. It depends on the finished form of biological fertilizer you want.
The powder process:
The powder process will be simpler than the granular biofertilizer process. First of all, the dehydration of cow dung compost treatment, fermentation good cow dung to pieces. If you want to powder biological fertilizer, after crushing screening can directly packaging.
Pelletizing production line:
Then, crush the raw material into the granulation process, secondary screening after granulation. Then it’s time to dry, cool and pack. You can also spray some coating agent to better store microbial fertilizer. The Australian customer wanted to produce a granular biofertilizer, and we recommended this method for him.
What kind of dehydrator to choose?
The Australian customer asked what kind of equipment could dehydrate fresh cow manure quickly and efficiently. YUSHUNXIN has two kinds of dewatering equipment: solid-liquid separator and inclined screen dehydrator. The water content of fresh cow manure is generally around 70% to 80%, so we recommend a solid-liquid separator to our customers. It uses a spiral extrusion method to quickly dehydrate cow manure. The moisture content of dehydrated cow manure is about 30%. The standard dimensions of the sieves’ holes is about 0.5mm. When you want to buy dehydration equipment, please tell us your raw materials to help you recommend the right equipment.
How to dispose of cow manure?
Cow manure is a common organic material, and this Australian customer has abundant resources of cow manure. But there may be some pathogenic bacteria and parasites in fresh cow manure, which can not be directly used as biofertilizer raw materials. To avoid adverse effects on crops, it is common to compost fresh cow manure and turn it into organic fertilizer before using it.
In the production of commercial biofertilizers, turning equipment can be used to speed up the fermentation turning speed. According to the customer’s output, we recommend the corresponding fermentation and stacking equipment. If you also need to pile cow manure, please contact us, YUSHUNXIN has a variety of pile equipment.
What is the granulation equipment used to make biofertilizer from cow dung?
Since the customer wanted to make granular cow dung biofertilizer and asked if there was a suitable granulation machine. We introduced to him the drum granulator, the disc granulator, and the roll extrusion granulator.
The drum granulator:
The drum granulator has a large output and can produce 1-30 tons of microbial fertilizer per hour. At the same time, the lining is anticorrosion material, and the cleaning hole can knock off the fertilizer on the wall to reduce waste.
The disk granulator:
The material of the disk granulator gradually forms a granular shape as the disk rotates. The output is relatively small, about 2-6 tons per hour. It can adjust the biological fertilizer size by disk and bearing Angle.
The roller extrusion granulator:
Different from other granulators, the roller extrusion granulator is a dry granulation process, which can produce a variety of shapes of biofertilizer particles. Finally, after consideration, the customer chose the drum granulator.
