What Is the Difference Between the Granulation Method of Stirring Tooth Granulator and disc Granulator?

FPC disc granulator has the following advantages: high spheroidization rate, high roundness and strength of particles, intuitive operation, convenient maintenance, etc.

The working principle of the disc granulator: The powdered fertilizer is evenly moistened by the atomized water in the double-shaft mixer to form a spherical core with a uniform particle size, and then sent to the spherical disc for granulation. The moisture content of raw materials should be controlled at 12~14%. Most of the water should be added in the double-shaft mixer, and only a small amount of supplemental water should be added to the ball pan, and the supplemental water amount should be controlled at about 0~3%. Dry powder granulation is directly added to the ball-forming disc, and an appropriate amount of water is sprayed. After the raw material ball core enters the ball-forming disc, it moves along a parabola under the action of centrifugal force, friction and gravity in the disc. Due to the cohesiveness and plasticity of the material, the cores adhere to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the high speed of the disc edge and the water content are constant, the material balls of different particle sizes will leave the disc edge and roll down at different detachment angles due to different gravity. The material ball continuously pushes the water out of the surface during the continuous rolling process. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the material ball has a certain strength, and then with the rotation of the inclined plate body The edge of the disc is discharged out of the disc.

Stirring-teeth granulator:

The new type of organic fertilizer granulator is also called a spiral stirring tooth structure due to its internal structure , Granulation, spheroidization, densification and other processes, so as to achieve the purpose of granulation. The particle shape is spherical, the particle size is generally between 0.3-3 mm, and the granulation rate is 90%. The size of 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 higher the rotation speed, and the larger the particle size. Small, 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 quality of the pellets. It is generally required that the particle size of the material before granulation should be less than 200 mesh. Typical application materials: chicken manure, pig manure, cow manure, carbon black, clay, kaolin, etc.

It is dedicated to the granulation of municipal solid waste organic fermented fertilizer such as manure, compost, green manure, sea manure, cake manure, grass charcoal, soil and miscellaneous manure, three wastes, microorganisms, etc. The particles are spherulites. The granulation rate of the machine is as high as 80-90%, and it is suitable for a variety of different formulas. The compressive strength of organic fertilizer is higher than that of discs and drums. The rate of large balls is less than 15%. The uniformity of particle size can be customized according to user requirements. It is adjusted through the stepless speed regulation function of this machine. This machine is suitable for the direct granulation of organic fertilizer after fermentation, which saves the drying process and greatly reduces the manufacturing cost.
