For those who want to produce organic fertilizer with a richer nutrient content, bio fertilizer manufacturing is an ideal choice. On 5th June 2023, a customer from the United States inquired about how to make bio fertilizer. This client planned to use cattle manure, biogas-slurry, ricebrand or husks, tithonia diversifolia leaves, cassava dregs and azotobacter as raw materials. And the output is about 20 tons per hour. But he hesitated whether to produce powder organic fertilizer or granular? According to the biofertilizer making budget, we send him a system involves 5 t/h new type granulation and 15 t/h powder bio fertilizer production design.The following are the specific details of communication in this case:

How to produce 20 tons of bio fertilizer from cattle manure?

If you want to make biofertilizer in the United States with 20 TPH output, we recommend you buy a rotary drum granulation line. Because it has advantages of large capacity and high erosion resistance.

In general, it consists of 9 parts. Including wheel compost turner, dynamic batching machine, SXFLF-1000 vertical compost crusher, double shaft horizontal mixers, SXZGZ-3210 rotary drum granulator, SXGS-2080 sieving machine, SXHG-2424 compost dryers, SXHG-2424 rotary coolers, fertilizer coating equipment and double bucket packing machine. In general, the large scale organic fertilizer making line costs about $500,000.

Can you give me a more cost-effective bio fertilizer making factory ooperation plan?

The American biofertilizer manufacturer told us his budget for the bio fertilizer production project is $300,000. Is there a more cost-effective solution? The answer is yes. For starting 20 TPH bio organic fertilizer manufacturing from cow dung with $300,000 investment, you can choose buy a combination of a 15 t/h powdery biological fertilizer making line and a 5 TPH organic biofertilizer granulation system. Here, 20 TPH capacity bio fertilizer equipment, it needs these as follows:

Turning raw materials piles to facilitate composting process to kill harmful substances in cow manure and niogas slurry. For 20 t/h large scale organic composting, we recommend you use wheel compost turner. Because its turning span is 8-30 m, which is wider than other organic fertilizer compost machines.

After composting cow dung and biogas slurry, you need to feeding them with rice husks, tithonia diversifolia leaves, cassava dregs, etc.  Here, dynamic batching machine can help you control proportion of every raw materials strictly. In addition, the material hopper number can designed according to your requirement

Next, it is time to crushing cow dung compost mixture into fine fine powder. For this, the vertical fertilizer crusher is the best choice. For one thing, its large capacity is suitable for you. For another, there is no screen mesh. So, it can grind biofertilizer compost without blocking.

Double shaft mixer for better bio fertilizer making

For the combined bio fertilizer making line, it is advisable to add azotobacter bacteria during mixing. In this way, you can make azotobacter organic fertilizer into powder and granules easier. Here, you need two sets of double shaft horizontal mixers.

Then, for 15 TPH powdery cow dung biofertilizer making, you can transport 3/4 products to double bucket powder fertilizer packing machine. At the same time, the left compost powder will be sent to produce bio organic fertilizer granules.

What equipment is used in 5 t/h bio fertilizer granule production line?

After mixing and azotobacter adding, the material need to pass the following machines to make cow manure biofertilizer pellets.

New type bio fertilizer granulator

Because the customer from the United States need to produce 5 tons of bio fertilizer per hour. We recommend him purchase SXJZ-1200 new type granulator. The equipment has advantages of high granulation rate of 97% and higher hardness bacterial fertilizer pellets making. Generally, it can fully meet your needs of 2-5 mm size cow manure azotobacter biofertilizer manufacturing.

Fertilizer screening equipment

Biological fertilizer granule screener

After make cow dung compost into biofertilizer granules, screening machine is necessary. It can help you sieve out granulated biofertilizer with required size. Like the United States customer wanted to make 3-4 mm bio organic fertilizer particles. This will return other material to crushing and granulation again.

Dryer and cooler

If you use new type granulation equipment to make bio fertilizer, dryer and cooler is necessary. They can reduce the moisture content of bio fertilizer pellets to below 10%. This means lower possibility of pulverization, so the produced bio fertilizer is more convenient for transportation and storage. For 5 t/h output, SXHG-1515 rotary dryer and fertilizer cooler are best choice. Compared to 20 TPH large scale biofertilizer making, it only need one set of biofertilizer drying machine.

Fertilizer drying and cooling machines installation

In sum up, a complete 10 t/h bio fertilizer granulation line consists of windrow composter, batching machine, semi-wet materials crusher, powder screener, mixer, new type/ flat die granulator, pellets sieve, (dryer and cooler), coating machine, automatic packaging scale and belt conveyor.

When is it suitable to add azotobacter in the bio fertilizer making process?

As mentioned above, this American client planned to use azotobacter to make biofertilizer. Azotobacter uses organic matter in the soil as a carbon source and converts it to plant-usable combined nitrogen to facilitate the growth of crops and plants. However, will the above steps have negative impacts on azotobacter?

When is it suitable for adding microbiology? In order to prevent azotobacter from high temperature killing, we recommend you add bacteria after composting during powder biofertilizer manufacturing. How about making granular biofertilizer? It is advisable to add microorganism after rotary drying.

The above are details about our communication with the customer about bio fertilizer making in the United States. In addition, we can also provide you with many other fertilizer making business plans. Such as organic fertilizer production plan, NPK fertilizer making line, etc.
