High Efficiency And High Capacity Industrial Drying Equipment For
Drying Sand
Process Flow:
The sand will be fed into the hopper by the wheel loader after a
period of time natural dehydration, and
fed to the conveying device by the feeder at the bottom of the
hopper, and then transported to the
feeding head end of the dryer.
When material enters the dryer, the special feeder is adopted to do
the sealing in order to minimize the
entry of the cool air.
The heat exchange happens with the hot air introduced from the heat
passing through pipe while the
material is entering the dryer. The material is lifted up and moved
forward with the rotation of the dryer,
enter the middle cylinder from the inner cylinder and return, and
then move to the discharging end after
entering the outer cylinder. The special unloader is still adopted
while the material is discharged from
the dryer to prevent the cool air and maximize the reduction of the
entry of cool air, to increase the
efficiency of the dryer and reduce the pressure load of the induced
draft fan and the burden of later stage
dust collecting. According to the needs, the material can be
transported to the finished products’ bin by
the conveying device or packed after discharging from the dryer.
The air temperature at the discharging
end will be reduced to 80-120℃ with increased humidity,
After the heat exchange, the air temperature in the discharging end
is reduced to 80-120℃ with the
increased humidity, under the function of the induced draft fan, it
will be discharged into the atmosphere
after the primary and secondary dust remover processing.
The fully automatic PLC control can be adopted in the equipment of
complete set of granular material
industrial drying equipment. There are temperature measuring
devices both at the feeding and
discharging end of the dryer hoist, which can be linked with
inverter of the blast stove, feeder, and
induced draft fan, dryer hoist, to reach its best performance and
highest capacity with the least man
power.
System Advantages:
High thermal efficiency
Heat preservation material with high heat resistance, combined with
feature of the heat utilization of
three cylinder dryer, the energy saving effect is obvious.
Low equipment investment
The material temperature is <50℃, which can be directly entered
into the material warehouse, and
cooling device is not required; tail gas temperature is low, the
dust removal equipment is with longer
service life.
Small ground space, easy to install
Its covered area is 50% less than that of the single cylinder
dryer, construction investment reduced by
50% and the electricity consumption is reduced by 60%, the layout
of granular material industrial drying
equipment is compact with simple process flow.
