Pan granulator is divided into unpowered scraper disc granulator (PQW) and powered scraper disc granulator (PQ). The two kinds of disc granulator are all have the feature of simple structure, convenient operation, the moisture of pellet can be easily control and high hardness.
1. The scraper device composed by unpowered scraper and powered scraper, which supporting the use of optimized disc when cleaning the bottom and side, then the pelletizing result is very well and qualified pellets can be reached over 90%.
2. Both of them have advantages like simple structure, easy operation, easy mositure content controlling and high strength of ball etc.
3. The pan granulator have adopt whole set of structure with mutiple steel plate strengthen with durable operation; reducer and motor have driving by flexible belt with steady starting and reduce the impact force of equipment, which also will extend the using life.
4. Novel structure with light weight and low height, and convenient process layout;
The uniform particle core was made by raw material powder, then sent into the disc, after that the core go along a parabola by centrifugal force, friction force and gravity in the disc, the moisture will go out of the core surface in the rolling process, because of the cohesiveness and plasticity, the core will become bigger with raw powder in the process. The pellet has well intensity because of the material cohesiveness and the natural volatilization of surface liquid film. When the disc inclination, edge height, rotate speed and moisture all fixed, the pellets with different diameter will rolling down from disc edge by different angle cause of different gravity, then discharging from the disc edge by rotating inclined disc body.
