The working principle of drum granulators commonly used in NPK fertilizer production lines

This new type of organic fertilizer granulator is also known as the internal rotation stirring tooth granulator and is widely used in the granulation of organic fertilizer. In the compound fertilizer production process, due to the high granulation rate, stable operation, sturdy and durable equipment, and long service life, it is selected as the ideal product by the majority of users. The internal-rotating tooth granulator developed and produced by our company has various specifications of Φ600 and Φ800. We can also develop and produce other specifications of stirring tooth granulator according to user requirements. The shell of the granulator is made of thick seamless steel pipe, which is strong and durable without deformation. Coupled with a stable base design, it runs more smoothly.

The new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously realize the process of mixing, granulating, spheroidizing, and densifying the fine powder in the machine to achieve the purpose of granulation. The particle shape is spherical, the sphericity is ≥0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥90%. The particle diameter can be appropriately adjusted by the mixing amount of the material and the spindle speed. Generally, the lower the mixing amount, the rotation speed The higher the particle size, the smaller the particle size, and vice versa. Application range: This machine is especially suitable for the granulation of light and fine powder materials. The finer the basic particles of the fine powder material, the higher the sphericity of the particles and the better the ball quality. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.

It is specially used for granulation of urban domestic waste organic fermented fertilizers such as organic fertilizer raw materials, livestock and poultry manure, compost fertilizer, green manure, sea manure, cake fertilizer, grass charcoal, soil and miscellaneous fertilizer, three waste, microorganism The particles are spherical particles. The qualified granulation rate of this machine is as high as 80-90%, and it is suitable for a variety of different formulations. The compressive strength of organic fertilizer is higher than that of discs and drums, the rate of large balls is less than 15%, and the uniformity of particle size can be passed according to user requirements. This machine stepless speed regulation function adjustment. This machine is more suitable for direct granulation of organic fertilizer after fermentation, saving drying process and greatly reducing manufacturing cost. Now this new type of organic fertilizer wet granulator is popular among users. Huaqiang wet organic fertilizer granulator is in short supply. The birth of new products, new production technology, energy saving and environmental protection are trustworthy!
