Xporting Customized Rotary Drum Dryer Drying Equipment Industrial
Rotary Drum Sludge Dryer Machine
Hollow Paddle Dryer is a kind of mixing dryer at low speed by
conducting heating.
Paddle Dryer has compact structure, big heat transfer area and
small floor area.
As well as small air consumption and less dust during drying,
paddle has self-clean function.
It also has long material residence time and high packing
coefficient and could be used in auto-production line for
continuous fabrication.
Principle
After been filtered and heated the air enters into the air
distrbutor on the top of the dryer.The hot air enters into the
drying room in the spiral form and uniformly. Passing through the
high-speed centrifugal sprayer on the top of the tower,the material
liquid will rotate and be sprayed into the extremely fine mist
liquid beads.Trough the very short time of contacting the heat
air,the materials can be dried into the final products.The final
products will be discharged continuously from the bottom of the
drying tower and from the cyclones. The waste gas will be
discharged from blower.
Features
1.compact structure, effective heat transfer area, small area
2.The mixing is uniform, high thermal efficiency, good drying
effect
3.the blade shaft can mesh with each other, with self-cleaning
effect, can prevent the material wall
4.Even of low energy consumption, small operating costs
5.small dust entrainment, less material loss
6.Indirect heating, no material pollution
7.The low rotation speed of liraglug impeller shaft, does not
damage the product shape and properties
8.Therefore the device to operate flexible, smooth and reliable
operation
Centrifugal spray atomizer Features
1.The drying speed is high when the material liquid is atomized,the
surface area of the material will increase greatly.In the hot-air
flow,95%-98% of water can be evaporated at a moment.The time of
completing the drying is only several seconds. This is especially
suitable for drying the heat sensitive materials.
2. Its final products own the good uniformity, flow ability &
solubility. And the final products are high in purity and good in
quality.
3. The production procedures are simple and the operation and
control are easy.The liquid with moisture contents of 40-60%(for
special materials,the contents might be up to 90%).can be dried
into the powder or particle products once a time. After the drying process, there is no need for smashing
and sorting,so as to reduce the operation procedures in the
production and to enhance the product purity.The product particle
diameters,looseness and water contents can be adjusted through
changing the operation condition within a certain range. It is very
convenient to carry out control and managment.
