Commercial Organic Fertilizer Production and Granulation Process

Classification & Production Standards of Commercial Organic Fertilizer
Main types of commercial organic fertilizer can be classified into several types in accordance with its working conditions and nutrient content, including organic fertilizer, organic and inorganic fertilizer, and bio-organic fertilizer.
The Bio-organic Fertilizer refers to fertilizer produced by special and functional microorganism after harmless treatment and decomposition with composite organic materials. Now, let me introduce bio organic fertilizer manufacturing process for you.

Commonly Used Composting & Granulation Machines in Commercial Organic Fertilizer Production

It is essential for manufacturers to choose the right fertilizer machines. There are many factors affecting the quality of commercial organic fertilizer, equipment being the most important one.
Commercial organic fertilizer production mainly includes 2 processes. One is harmless organic waste treatment process: compost-making materials decomposition and fermentation. The main raw materials for commercial organic fertilizer production includes animal manure, municipal sewage sludge, garbage, candy pomace, crop stalks, paper filter mud, food and fermentation organic industrial waste, etc. The heat produced by thermophilic bacteria kills pathogenic microorganisms, viruses, bacteria, protozoa, worms and eggs that may inhabit wastes.
The other part is the granulation process of composting material. Benefits of organics granulation is to make organic fertilizer have good commercial properties, stable nutrient content and fertilizer efficiency for further storage, transportation and sale.

◇ 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.

◇ Fermented organic material granulation

Fermented organic materials are characterized by coarse texture, poor adhesion and 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 rotary fertilizer granulator production line.


Extrusion granulation
: composting material with an appropriate amount of inorganic fertilizer is extruded by flat die extrusion granulator, and then organic fertilizer is directly bagging. This production has strict requirements of materials selection and pre-treatment. It needs to adjust to appropriate water content. Meanwhile, it requires fine texture and good adhesion. It features simple process, no drying process, high product water content, coarse columnar grains, and uniform particle size. However, it has easy collapsibility in the storage and transportation process and low production capacity.

Disc granulation
: Almost all organic materials can be granulated with a disc fertilizer granulation technology. After material drying and finely pulverized with an adequate amount of fertilizer, materials are sending into thedisc granulator machine. The materials are mixed and bonded by humidifier spraying. With the rotation of the disc granulator, materials are produced to granules, and then it is sieved and dried again. Finally, it can be bagging. This kind of organic fertilizer production has modest production power, needs small power. The granules are in size of round shape. Before granulation, organic fertilizer raw materials need to be dried and crushed.


New type granulation
: new type organic fertilizer granulator is advanced fertilizer granulator machine. It can be used for all kinds of organic matters. There is no drying and crushing in organic fertilizer production. Mix organic raw materials in the machine, and then it can produce spherical granules. The organic matter content can reach to 100%, which is really pure organic material granulation. There is no need to dry fermented organic materials. The water content of organic raw materials can be 20-40%. The granulation rate is over 95%.

Drum granulation: Adopting a unique design in the rotary drum granulator, material particles collide with each other and organic materials with high humidity can be directly granulated. With wide range of applications and no special requirements on the material, it is widely used in large-scale organic fertilizer production line. In addition, it can directly produce organic fertilizer eliminating the need for pre-drying and crushing. The granules are spherical particles. With high granulating rate, drum organic fertilizer has good appearance.

What is New Type Organic Fertilizer Granulator?

New Organic Fertilizer Granulation Machine is one of organic fertilizer equipment. It is the latest product of institute of agricultural machinery with years of experience in organic fertilizer processing equipment design and development, and has won the national utility model patent. It is used for granulation of fermented organic matter to break through conventional granulation processing. Before being granulated, there is no need to dry the raw materials, raw materials and ingredients which can be processed directly into spherical particle. This can save large amounts of energy. Granulation rate and organic content is up to 100%. Organic particles can be characteristic of being able to inlay each other while growing up and granulated without bonding agent. Particle is screened strictly, which saves drying energy. The content of raw materials and water is 20%-40%.
How Does New Type Organic Fertilizer Granulator Work?
New type organic fertilizer granulator consists of machine body, driving part and granulating rotor. The machine body and driving part are mainly fixed on a machine frame, ensuring the sturdy construction, stable performance and easy installation of the granulator machine.The motor and speed reducer of the driving part drive the rotor to rotate. After the materials enter into the organic fertilizer machine through the feeding inlet, by the high speed rotating mechanical stirring force and aerodynamic force thereof, the materials are mixed, granulated, spherified and densified in the machine, achieving the aim of granulation. The formed granules are pushed out in the other end of the equipment.
Note: The diameter of the produced granules can be controlled by adjusting the quantity of the raw materials and rotating speed of main shaft. The less the raw materials mixed and the higher the rotating speed, the smaller the granulated fertilizer.
What is New Type Organic Fertilizer Granulation Machine Application?

1. The organic fertilizers with turfs, lignite, sludge of organic fertilizes and straws as materials can be made into granules;
2. Organic fertilizers or organic compound fertilizer granulation with chicken manure (animal manure) as materials;
3. Cake fertilizer granulation with bean cakes as the main materials;
4. Organic fertilizer granulation with residues of urban rubbish or sewage treatment plants as materials.
