Pan Granualtion Equipment Working Principle

In the process of compound fertilizer powder processing, there are many factors that affect the granulation rate of disc granulator, but the influence of each parameter is not isolated, but interrelated and included. In NPK chemical fertilizer production line, the relationship between parameters should be adjusted according to the actual situation, so as to achieve the best spherical yield.

Ball forming principle of Pan fertilizer granulator

The disc is mounted at a certain inclination. The material in the rotating disc rolls rapidly with the rotation of the main body of the disc. When it rises to the highest position, it falls vertically under the block of the scraper. 

In the process of rotating the disk, it is squeezed and rolled by the disk wall under the action of centrifugal force. As a result of these all-round mechanical extrusion, rolling, collision, powder materials gathered together, with the help of the surface tension of the liquid phase, the "mother ball" is formed. With the increase of "mother ball", the particles are gradually spheroidized into complete particles, and the strength increases gradually from small to large. 

The granulation process is completed until the particle size of the finished product overflows from the edge of the disc. The disc granulator has a good classification function, so that the powder material grows from the bottom of the disc to the earth, forming particles overflow to the outer disk. 

With the increase of the diameter of the outer disk, the linear velocity of the particles increases suddenly. Particles are rolled and rubbed to form spherical particles. Larger particles are prevented from spilling into the hopper by the discharge plate and then sent to the next process by the belt conveyor.

The chemical fertilizer is also produced in different proportions of different chemical fertilizers. Due to the influence of different fertilizer types, in order to achieve high ball rate, the parameters of fertilizer granulator should be adjusted according to the specific situation, so as to achieve the best granulation effect and improve the production capacity.
