How to Make Organic Fertilizer Pellets?

As we all know, there is a long history for making organic fertilizer. From using animal manure directly to making organic fertilizer compost, it develops to make organic fertilizer pellets or granules. However, what is the whole organic fertilizer production process? Generally speaking, it can be divided into two main steps, composting and granulation.

◇ Organic materials fermentation and decomposition

It usually adopts aerobic fermentation as the core of compact treatment in commercial organic fertilizer industrial production. The process consists of solid-liquid separation, material pre-treatment, fermentation, turning and decomposition. Studies have shown that the essence of the fermentation process is microbial decomposition of organic matter, wherein the amount of gas, temperature, humidity, and C/N are the main fermentation parameters, so the key technology of the regulation is to create a suitable environment for the aerobic microorganisms. In the retting process, heap mild pH value rising leads to nitrogen volatilization losses. Reducing nitrogen loss and preventing excessive organic matter decomposition of organic fertilizer are the keys to improve the organic fertilizer quality. The above problems can be solved by improving material pre-treatment, adjusting C/N, moisture, pH, and controlling temperature and fermentation time.

granulating difficulty. It has been bottleneck in organic fertilizer production for a long time. Organic fertilizer granulation can be in extrusion granulator organic production line and disc granulation organic fertilizer production line. Recently, organic fertilizer production can be processing in new type fertilizer granulator production line and pan fertilizer granulator production line.

While we buying fertilizer making machine, we always want to know which one is the most suitable fertilizer machinery for us and how to choose the best fertilizer machine. Now, let me introduce fertilizer making machine information for you.

1. Compost turner machine: for commercial fertilizer production, compost making machine is necessary for the whole organic fertilizer manufacturing production. It not only increases turning efficiency and it saves composting time, which only takes 7-15 days for organic fertilizer fermentation.

2. Fertilizer crusher:  organic fertilizer crusher can crush the organic matters in the sludge, biogas digester, chicken manure, pig manure, cow dung fermentation, etc.

3. Fertilizer mixer:  fertilizer mixing machine is suitable for blending the formula feed, concentrated feed, additive premix, and raw materials of organic fertilizer.

4. Fertilizer granulator machine: organic fertilizer granulation is the most important process in the whole organic fertilizer production. It directly has an effect on fertilizer size, fertilizer strength and fertilizer quality.

5. Fertilizer dryer: rotary drum drying machine is used for drying compound fertilizer granular, organic fertilizer granular, animal manure, etc. High efficiency, evenly drying effect, stable operation, long service time.

6. Fertilizer cooler: Rotary drum cooling machine is used to cool fertilizer with certain temperature and particle size in compound fertilizer production line and organic fertilizer production line.

7. Fertilizer screening machine: Rotary drum screen is used for size separation of compound fertilizer and organic fertilizer. High screening efficiency, stable operation. Adopt combined screen, easy for maintenance and replacement.

8. Fertilizer packaging machine: The fertilizer packaging machine is mainly used for automatic quantitative weighing & packaging of powder and granule materials.

In fact, there are other accessory fertilizer machine in organic fertilizer manufacturing process. such as belt conveyor, fertilizer coating machine, organic fertilizer polishing machine, etc. In general speaking, the total organic fertilizer production process is Hydraulic Compost Turner (raw materials fermentation) → Pan Feeder (smooth feeding) → High Moisture Fertilizer Crusher (fermented materials crushing) → Disc Granulator (materials granulating) → Rotary Drum Dryer (fertilizer drying) → Rotary Drum Cooler (fertilizer cooling) → Drum Sifting Machine (fertilizer screening) → Organic Fertilizer Coating Machine (finished products coating) → Automatic Packing Machine (fertilizer packaging) → Vertical Crusher (substandard products crushing for re-granulating) → Belt Conveyor (raw materials and finished products transporting)
