Rotary dryer sludge rotary drum dryer rotary vacuum dryer
Single cylinder Rotary dryer is widely used for drying slag
limestone,coal powder,slag,clay,etc.The dryer can also be used in
building materials,metallurgy,chemical, and cement industry.Rotary
Dryer mainly consists of dryer body,raw material feeding
plate,driving and supporting device,seal ring,etc.Dryer can be
generally divided into four types,they are rotary dryer,triple-drum
dryer,indirect heat transfer dryer,vertical dryer.Different kind of
dryer has its own characters and advantages,the specific choice of
a special dryer depends on different elements.
- The drying strength is high, and since the materials are highly
dispersed in the gas stream, the entire surface of the particles is
actively dry and effective.
- Short drying time.
- The air dryer has a simple structure, a small footprint, and is
easy to build and maintain.
- Large amount of processing, high thermal efficiency. When drying
unbound water, the thermal efficiency can reach 60%.
- The dryer achieves "zero horizontal thrust", which greatly reduces
the wear of the brace wheel and ensures smooth and reliable
operation of the barrel.
- Dryer adopts "aligning roller device", so that the support of the
roller and the roller will always be in linear contact, thus
greatly reducing wear and power loss.
1. Yuhong coal dryer, with strong overload capacity, large
quantity, less fuel consumption, low dry cost; Applies the
downstream drying method, flue gas and wet material in the dryer on
one side of the dryer, can take advantage of the high temperature
gas to achieve high evaporative force, low temperature dryer
output, with high efficiency thermal;
2. Can change the working parameters according to different
material properties, the material in the drying cylinder body can
form a durable curtain fabric and more convenient heat exchange;
3. New type of feeding and unloading device, preventing food blockage
of drum dryers, uninterrupted and uneven return phenomenon, reduce
the load of dust collection system;
4. A type of internal structure, to enhance the cleaning effect of
dispersed material and thermal conductivity, remove the cylinder in
moisture, has more flexible adaptation of adhesion and moisture of
5. In the new type of coal slurry drying device to achieve "zero
thrust", greatly reducing the wear of the wheels, the cylinder has
smooth and reliable operation;
6. The dryer acquires a "wheel self-adjusting device", makes the
wheel and roller ring with linear contact, thereby greatly reducing
wear and energy loss; Adopt the unique technology of large carbon
retardation absorption, ensure the uniformity of coal drying.
The quality of building materials continues to increase, energy and
raw material consumption are declining year by year, new types of
new building materials continue to emerge, and building materials
are constantly upgraded. As a result, the requirements for the
processing technology of building materials have been continuously
improved. For example, the control requirements for impurities and
moisture content of raw materials have been continuously improved.
Only in this way can products with guaranteed quality be produced.
The wet material is sent to the hopper by the belt conveyor or the
bucket elevator, and then through the feed pipe to the feeding end
through the feeder of the hopper. The slope of the feed pipe is
greater than the natural inclination of the material so that the
material can flow smoothly into the dryer. The dryer cylinder is a
rotating cylinder slightly inclined to the horizontal line. The
material is added from the higher end, and the heat carrier enters
from the low end, and is in countercurrent contact with the
material. There is also a heat carrier and the material flow into
the barrel together. As the cylinder's rotating material is moved
by gravity to the bottom end. During the forward movement of the
wet material in the cylinder body, the heating of the heating
medium is obtained directly or indirectly, so that the wet material
can be dried, and then sent out at the discharge end via a belt
conveyor or screw conveyor. A copy board is installed on the inner
wall of the barrel, and its function is to copy the materials and
scatter them, so that the contact surface of the materials and the
air flow is increased, so as to increase the drying rate and
promote the advancement of the materials. Heat carrier is generally
divided into hot air, flue gas and so on. After the heat carrier
passes through the dryer, a cyclone dust collector is generally
required to trap the material contained in the gas. If it is
necessary to further reduce the dust content of the tail gas, it
should also be discharged after bag filter or wet filter

Packing and shipping
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.
