The working principle and granulation process of the stirring tooth granulator

fertilizer granulator Dec 6, 2023

The organic fertilizer agitator granulator is used to granulate various organic substances 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.

The complete production line of stock conversion, stirring, and granulation is used to process organic raw materials after fermentation. It combines various advantages. Before granulation, the fermented raw materials are crushed, and the ingredients are directly mixed with a mixer into the stirring tooth granulator machine to produce spherical particles. The particles produced by this machine are spherical, with an organic content of up to 100%, greatly saving energy and improving utilization efficiency. The direct goal of the customer has been achieved by directly processing pure organic matter into particles, and utilizing the characteristic of organic fertilizer raw materials being embedded and enlarged under certain conditions. No additives, adhesives, etc. need to be added during granulation. After the finished product is produced, the particle strength is very good. After granulation, it is directly screened to reduce drying energy consumption and save coal electricity.

The working principle of the stirring tooth granulator equipment is to use the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, compact and other processes of 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 ≥ 80%. 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, the higher the speed, and the smaller the particle.

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

fertilizer granulator Dec 6, 2023

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.
