Product Decription
Three-drum dryer also called three-cylinder dryer, enjoys the
Germany advanced technology.
The three-drum dryer is made up of three layers of sleeves:
internal, middle and external one. Both the internal and middle
drums are two-dimension ones and the external drum is a vertical
one, which makes the most use of the drying drums.
The three-drum dryer's drum length is 25%-35% of the monocular
dryer's, thus decreasing the covering area of the machine.
Three-drum dryer or three-cylinder dyer is mainly used to dry
granular materials with certain humidity and particle size, such as
yellow sand, foundry sand, slag, coal cinder, clay with small
particle size and other granular materials that resist to high
temperature, dust and smoke.
Moisture content of materials after drying can reach 1 to 0.5 % or
below. It is one of the wet materials drying equipment, which is
highly efficient and energy-saving product improved on the basis of
single-cylinder rotary dryer. After application of various
enterprises and industries, three-drum dryer has achieved good
results and well received by various customers.
Three-drum dryer has improved internal structure of monocular
dryer, which prolongs the time of pre-drying of wet materials and
wet materials in the machine, thus improving 50% to 80% of
production capacity compared with original monocular dryer.
Working principle of The sand dryer:
Special three tube structure, it formed a oneself insulation system
through the inside cylinder and the
middle cylinder was surrounded by the outside cylinder, the surface
of the inside and middle cylinder
dryer release invoved in the outside layer in the cylinder
materials heat exchanger, thus the outer tube
lie in the heat flow low-temperature terminal. So the cooling area
and heat loss of the cylinder is
decreased obviously.
Heat Source
The heat source of the dryer is coal, electricity, gas,
etc.Material hot atmosphere flow during drying and radiant, hot air
drying cylinder is the heat flow from the tail, to move forward
with a good contact with the material, through the heat conduction,
convection and radiation heat transfer make full use of;Pass heat
directly to the material, make the material moisture to evaporate
in the cylinder body are constantly being, into the mouth of the
wind device take out a large number of moisture, wet, prevent
secondary pollution caused by the dust outside;Through internal
spiral stirring, scavenging, copying plate, press the material
movement, complete the drying process;Reverse flow dehumidification
to avoid reducing repeat drying procedures.
