Stable Operation Disc Pelletizer, Convenient Control Fertilizer Granulation Equipment
The disc-type pelletizer is the main equipment for pelletizing powdery materials. It has the advantages of high pelletization rate, high pellet strength, stable operation, convenient control, and long service life. It can be widely used in chemical, cement, steel, pharmaceutical, Building materials and other industries.
Application of Disc Granulator:
The disc granulator is the main equipment for pelletizing by powder material and widely used in cement industry, steel industry and fertilizer industry.
Working principle of Disc Granulator:
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.
The working principle of the disc-type ball-making machine is: the disc body is driven by the transmission device to make a rotary motion around its center; when the powder is added to the ball-forming disc, the water-spraying device provided above the ball-forming disc sprays water, humidification, under the action of friction, the wet powder continuously rolls and rotates in the disc while gradually forming a cue ball. The wet cue ball continues to adhere to the powder and slowly grows. When the ball reaches a qualified particle size, under the action of centrifugal force and gravity, roll to the edge of the disk and expel it by itself.
