Our pan granulator bio-organic fertilizer production line could offer production of 20,000 tons/yer. It is proven by our customers that the whole organic fertilizer production process is centralized controlled, and all equipped fertilizer machines are highly automatic and easier to operate. The whole bio fertilizer plant is designed based on advanced and mature technologies. The fermentation system (compost windrow turner) can simultaneously make the best use of solar energy, bio-energy, and mechanical energy, greatly saving energy. The packaging system are controlled by the computer, ensuring the precision of finished products packing. The pan granulator bio fertilizer production line is suitable for organic materials, such as livestock and
poultry manure, dregs, papermaking sludge, and municipal solid waste. Benefits of Organic Fertilizer
After safety disposal and fermentation, raw materials are made into bio-organic fertilizers that contain a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus and potassium. Organic fertilizers not only provide comprehensive nutrition for plants & crops, also with long fertilizer effect, which can increase and update the soil organic matter, promote microbial breeding, and improve soil chemical and physical properties and biological activity. The disc granulator bio fertilizer production line is a complete set of equipment from raw materials collection to the organic fertilizer packaging.

Granulation Process of 20,000 Tons/year Organic Fertilizer Plant
1) Organic Materials Fermentation Process
This process plays the preliminary but indispensable role in the whole production line. There are 4 kinds of compost turns choosable for customers-double helix compost turner, self-propelled fertilizer turner, hydraulic compost mixer turner, and groove type fertilizer fermentation machine. They are widely used to turn and mix the compost and accelerate the fermentation speed.
2) Crushing Process
The compost lump materials should be ground before the granulation process. It is widely used in bio-fermentation of organic compost, MSW compost, carbon mud, rural straw waste, industrial organic waste, chicken manure, cow dung, sheep, pig, duck manure and other biological materials. The semi-wet material grinder is more suitable to crush lump compost fertilizer raw materials with moisture content between 25-55%.
3) Granulation Process
It is the core part in organic fertilizer production. Pan granulator is used in fertilizer plant with low output requirement. Fermented raw materials are uniformly bonded together due to the continuous rotation of the disc. Automatic cleaning equipment is installed in the upper part of the disc to prevent materials sticking to the wall, which greatly improves lifespan of the machine.
4) Drying Process Rotary drum drying machine is mainly used for drying the fertilizer with a certain degree of humidity and particle size. Materials are transported to the drum by belt conveyor. Rotary dryer is suitable for large, medium, and small farms. Different sources of heat are applied, such as coal gas producer, directly/indirectly heated stove, etc., according to different drying requirements of products.
5) Cooling Process
Rotary drum cooler is used for cooling fertilizers to make fertilizer particles stronger.
6) Screening Process
Our rotary drum sifting machine is used to separate the granules from the large particles which need to be returned for the second crushing and granulating. Rotary drum coating machine is used to coat the fertilizer and prevent the fertilizer from sticking together. Technical Data of Pan Granulator Organic Fertilizer Production Line
