How to use disc granulator to produce fertilizer granules of qualified size
In the process of using the disc granulator, it is inevitable to encounter large or small particles, so how to adjust the particle size of the disc pelletizer? Here is a detailed introduction of the organic fertilizer making machine manufacturer for you.
First of all, if the rotating speed of the disc is too fast, the more times the material rolls in the disc per unit time, the larger the particles will be, otherwise, the smaller the particles will be. Therefore, whether the rotating speed is reasonable or not plays an important role in the granulation process of fertilizer production line.
Secondly, the inclination angle of the disc of the disc granulator. The larger the inclination angle is, the greater the force of gravity on the material is, and the smaller the effective utilization area of the disc surface is, which directly affects the pelletizing rate of the disc granulator. Therefore, the inclination angle of the disc must be increased while the rotation speed is increased. As the inclination angle of the disc increases, the final rolling speed of the particles will also increase correspondingly, so the inclination angle of the disc should be kept at a pole Limit value to prevent damage to rolling and granulation of materials.
Disc granulator is generally suitable for the granulation of organic fertilizer, NPK fertilizer and compound fertilizer. Compared with rotary drum granulator, its price is lower. It is suitable for granulation process in most fertilizer plants.
Granulation principle of disc granulator
The disc pan granulator drives the disc to rotate through the motor and reducer. The materials in the disc roll along the disc surface under the action of gravity and centrifugal force. The powder materials collide with each other and finally form particles. With the increasing of particles, it overflows out of the disc.
Adjustment of particle size of disc granulator
The particle size is directly related to the rotation speed of the disc pelletizer and the inclination angle of the disc.First of all, if the rotating speed of the disc is too fast, the more times the material rolls in the disc per unit time, the larger the particles will be, otherwise, the smaller the particles will be. Therefore, whether the rotating speed is reasonable or not plays an important role in the granulation process of fertilizer production line.
Secondly, the inclination angle of the disc of the disc granulator. The larger the inclination angle is, the greater the force of gravity on the material is, and the smaller the effective utilization area of the disc surface is, which directly affects the pelletizing rate of the disc granulator. Therefore, the inclination angle of the disc must be increased while the rotation speed is increased. As the inclination angle of the disc increases, the final rolling speed of the particles will also increase correspondingly, so the inclination angle of the disc should be kept at a pole Limit value to prevent damage to rolling and granulation of materials.
Disc granulator is generally suitable for the granulation of organic fertilizer, NPK fertilizer and compound fertilizer. Compared with rotary drum granulator, its price is lower. It is suitable for granulation process in most fertilizer plants.
