Disc Granulator ,Organic Fertilizer Granulation Machine
Introduction:
ZK disc 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. The disc granulator adopts
massive structure, the disc bottom reinforced by multiple radiation
steel plate. The motor and reducer adopt flexible belt driving, so
the life time is increased by the smooth start and low impact.
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.
Structure:
The disc granulator is composed by disc, driving device, rack,
pedestal, scraper etc. The structure feature is:
1. The disc bottom reinforced by multiple radiation steel plate
with high strength and stiffness
2. The driving gear adopts high frequency quenching process with
long life time.
3. The reducer and motor adopt flexible belt driving with smooth
start and low impact.
4. The driving system installed bridging device which can reduce
the impact between gear and reducer, and increase the equipment
running stability, at the same time the main accessories working
life also increased.
5. The auxiliary power consumption was reduced by the unique
unpowered scraper device.
