The rolling time and frequency of the material in the rotary drum granulator are the primary factors that determine the ball formation rate and particle roundness.

The principle of drum granulation is that the material relies on surface tension, an appropriate amount of liquid phase, the squeezing force generated by rolling between the materials, and the material is centered on small particles in the correct direction of movement in the granulator. Form a ball. The higher the frequency of rolling in a certain period of time, the higher the ball formation rate and the rounder the particles.

During the production process, we have encountered two situations due to the different friction between the material and the wall of the pelletizer. One is that the internal surface of the granulator has a large surface finish, which reduces the friction between the material and the wall of the barrel, and weakens the power of the material to move upward. The material does not roll, and no particles are produced. In view of this situation, we can solve it by adjusting the speed of the granulator and installing a small copy board inside.

The second is that the material in the granulator is severely sticking to the wall. The friction between the material in the granulator and the wall of the barrel is increased, which raises the material in the machine too high, causing the material to fall from the top, so that the formed particles are not Rounding and excessive large particles,。

we think there are two reasons for this situation: on the one hand, the material is caused by too much viscous materials, this situation is solved by changing the process formula and reducing the amount of viscous materials;

on the other hand, The inside of the granulator is not smooth. This situation is solved by changing the internal material and increasing the smoothness of the inside of the granulator.
