Because the bio compound fertilizers have higher nutritional value, many bio organic fertilizer manufacturers have the plan to produce bio organic compound fertilizer. Today, we discuss the specific process, key equipment and precautions for the production of bio compound fertilizer.

Different from bio organic fertilizer production line, the production process of bio organic compound fertilizer is more complicated. Here’s how:

First, you need to compost organic waste (animal waste, crop residue). Then, crush the bio compost and inorganic fertilizer containing nitrogen, phosphorus, potassium into 30-50 mesh fine powder through bio fertilizer grinder. It is then mixed with powdered bacteria (nitrogen-fixing bacteria, phosphate-dissolving bacteria and other beneficial microorganisms) in proportion to the formula. Feed the powdered biological fertilizer into the biofertilizer granulator for granulation. You then use a drum dryer to remove moisture from the bio compound fertilizer particles. However, the temperature of the material after drying is higher, and it needs to be cooled. Then select uniform biological compound fertilizer granules for packaging. This is the complete process of bio compound fertilizer manufacturing.

The disk granulator comprises a granulating disc, a bacterial-spraying system, a transmission device and a support. The rotating disc drives the material to rotate and forms the rolling required for granulation under the action of gravity. At the same time, the spray system injects liquid bactericide and sprays it on the rolling material to aggregate it into granules. There are generally two disk granulators, and the use of the second machine can improve the particle strength of bio compound fertilizer and improve the particle shape. But if you are on a budget, just buy a disc granulator.
