The granulation principle and characteristics of organic fertilizer rotary drum granulator

drum granulator is a molding machine that can manufacture materials into specific shapes. The drum granulator is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation as well as large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after being humidified. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are compressed and agglomerated into balls.

The drum granulator is driven by the main electric motor to drive the belt and pulley. Drive to the driving shaft through a reducer, and work in opposite directions by meshing the split gear installed on the driving shaft with the large gear ring fixed on the body. The material is added from the feeding end and passes through the inside of the cylinder. Through the special structure inside the cylinder, it is made into particles and flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, large-scale production can be achieved.

Characteristics of organic fertilizer drum granulator:

1. The ball forming rate reaches 70%, with a small amount of returned material and small particle size, which can be re granulated;

2. Heating with steam to increase the temperature of the material, reducing the moisture content of the material after balling, and improving the drying efficiency;

3. Using rubber engineering plastic as the inner lining, the raw material is not easy to stick to the cylinder, and it plays a role in anti-corrosion and insulation;

4. Large output, low power consumption, and low maintenance costs.

The working principle and granulation characteristics of a chicken manure stirring toothed granulator

The chicken manure stirring toothed granulator is also known as the internal rotation stirring toothed granulator. The shell of the granulator is made of thickened seamless steel pipes, which are sturdy, durable, and do not deform. Combined with a stable base design, it operates more smoothly. Used for granulation of various organic compounds after fermentation, breaking through the conventional organic granulation process. Before granulation, the raw materials do not need to be dried or crushed, and spherical particles can be processed directly with ingredients, which can save a lot of energy.

Characteristics of the external rotation internal rotation organic fertilizer stirring tooth granulator: The produced particles are spherical. The organic content can reach up to 100%, achieving pure organic granulation. By utilizing the characteristic of organic matter particles being able to embed and grow together under certain forces, no binder is required during granulation. The particles are solid and can be sieved after granulation, reducing drying energy consumption. The organic matter after fermentation does not need to be dried, and the moisture content of the raw materials can be between 20-40%

Working principle of chicken manure stirring teeth granulator:

The chicken manure stirring toothed granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thereby achieving the purpose of granulation. The particle shape is spherical, with a sphericity of ≥ 0.7 and a particle size generally between 0.3-3 millimeters. The particle formation rate is high, and the size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount and the higher the speed, the smaller the particle, and vice versa. Application scope: This machine is particularly suitable for granulating lightweight fine powder materials. The finer the basic particles of fine powder materials, the higher the sphericity of the particles, and the better the quality of the pellets. The new type of organic fertilizer pelletizer is a newly developed pelletizing equipment for sludge, chicken manure, pig manure, cow manure, and straw, also known as the internal rotation stirring tooth pelletizer. Widely applicable for granulation of organic fertilizers. Due to its high granulation rate, smooth operation, sturdy and durable equipment, and long service life, it has been chosen as an ideal product by a large number of users.

Advantages and disadvantages of organic fertilizer granulators in wet granulation production lines

Granular fertilizer can add some inorganic components in fertilizer to improve fertilizer efficiency, while powdery fertilizer is easy to absorb moisture and caking if inorganic components are added. Granular fertilizer is more convenient to apply, especially in some large-scale planting bases, mechanical fertilization is generally used. If mechanical fertilization is used, only granular fertilizer can be used. If it is powdery, it is easy to fly everywhere.

Wet granulation is divided into many kinds of equipment, the early disc granulator, drum granulator, stirring granulator, organic fertilizer combination granulator and so on. Each granulation method is different for different raw materials, but it has one characteristic, that is, the moisture content of raw materials is generally 25% – 60%, and the requirements of moisture content are different with different equipment.
Disc granulator is an early granulation equipment for wet granulation. The moisture requirement is generally about 50%. The disc is used to make the materials roll on the disc and slowly stick together to form granules. It is suitable for relatively fine raw materials with low adhesion. Disadvantages: too high moisture, too much consumption in the later stage, and too high material requirements.
Among these granulating equipment, the most outstanding technology and performance are stirring teeth organic fertilizer granulator machine and organic fertilizer combination granulator machine. If it is pure organic matter granulation, it is recommended to choose stirring teeth granulation, which is suitable for a wide range of applications, and the water content can be controlled between 25% – 45%. Organic fertilizer combination granulator is mainly used to add some inorganic components (nitrogen, phosphorus, potassium, etc.) into the organic matter. The wet granulation material requires high moisture, and the consumption of drying and cooling is increased.

Factors affecting the price of organic fertilizer pelletizers in fertilizer production lines

If you want to invest in organic fertilizer granulator, the price of fertilizer equipment manufacturers is often different. How to choose your own suitable equipment when the fertilizer granulator machine price is not used? As long as you understand the difference of equipment price, you can choose fertilizer granulator pertinently.
One of the reasons for the price difference of organic fertilizer granulator: material quality
The same material, material thickness, integrity affect the price. No matter what kind of products, raw materials are worthy of being a common factor affecting prices. It is self-evident that the commonly used plates, some 10mm, 12mm and so on, have an important impact on the processing. Of course, the price will not be the same. For the integrity of a body, some are made of raw materials and leftover materials, and some are made of a complete piece of processing.

The second reason for the price difference of organic fertilizer granulator: the influence of power consumption
Organic fertilizer granulator machine is related to agricultural environmental protection equipment, and it also pursues environmental protection and energy saving. Energy saving performance is also a factor affecting the price. It is the same type of organic fertilizer granulator equipment. For one ton of organic fertilizer production, some models need 5kW energy consumption, while others need 8kw. How would you choose?
The third reason for the price difference of organic fertilizer granulator: the influence of unit capacity
The larger the unit capacity of organic fertilizer granulator machine, the higher the price. It is not difficult to imagine that there is a big price difference between an annual output of 50000 tons of organic fertilizer equipment and an annual output of 10000 tons of organic fertilizer equipment. It’s not only because of the number of large equipment, but also because of the different requirements of large and small equipment for process technology. The larger the unit capacity, the higher the corresponding requirements of process technology, and the higher the price
