There are many raw materials used to ferment biogas, but most of them are livestock and poultry manure, such as cow dung or chicken manure. After biogas production, it will produce waste biogas residues. These biogas residues are rich in a large amount of organic matter, which can  recycle it into fertilizer for sale. In this way, you can successfully dispose of these biogas residues, not waste them, and use them to generate income. So organic fertilizer production line you deserve.

How to Dispose of Biogas Residues as the Raw Material to Produce 2TPH Fertilizer?

The moisture in biogas residues is very high, if it is not dehydrated and directly made into fertilizer, it is difficult to condense into agglomerates. So you can use a solid-liquid separator for dehydration. Its output is 2-3t/h, just suitable for producing 2t/h organic fertilizer. You can prepare the dehydrated biogas residues for later production.

Can we dispose of biogas residues‘ moisture to 3%-5%?

After you use the solid-liquid separator to dispose of biogas residues, the moisture of the biogas residues is below 30%.  So if you want biogas residues‘ moisture of 3%-5%, you can equip a rotary dryer after the solid-liquid separator. You can choose the model- SXHG-1010, its output is 2-4t/h. And it is also very suitable for fertilizer production with 2t/h output.

2TPH Organic Fertilizer Pellets Production for Biogas Residues

Reasonable utilization of biogas residue can bring you the maximum benefit. But how to turn these biogas residues into treasures? You can use this biogas residue to produce organic fertilizer. Because the content of organic matter in these biogas residues is very high, which is a good raw material for the production of organic fertilizers. After dehydrating the biogas residues as mentioned above, you need to compost them to prepare for subsequent production. Crush and stir them all after composting, so that mixing the organic matter fully  and uniform in size. Next you can granulate. According to the output of 2t/h, you can choose the disc granulator. The granulation rate of this equipment can reach 93%, which can meet your granulation needs. Finally, the prepared granules you can dry and cool before being packaged.

Can we produce 8t/h biogas residues pellet fertilizer?

Of course. If you want to produce 8t/h granular fertilizer, you can choose drum granulator. Because the output of this equipment is 1-30t/h, which is suitable for large-scale production. And it is heated by steam during the production process to increase the temperature of the material. After balling the material , the moisture is low, and improving the drying efficiency . This way doesn’t waste time when you are drying high capacity of material.

How to Get Biogas Residue Pellets of Uniform Size?

After granulation, you can equip a sieving machine to screen the granules with consistent size for subsequent production. And those with inconsistent sizes can be sent back to the granulator through the conveyor belt for secondary granulation. Another way is that you equip a rounding machine after granulation. This machine grinds the particles through two rotating discs at high speed so that they are uniform in size. In addition, the rounding machine can polish the surface of the particles to make them look more beautiful.
