High Energy-efficient BH Rotary Sand Dryer Upgraded Deft design
Description:
Rotary Sand Dryers are one of the typical applying area of rotary
dryers due to its reliable performance, high efficiency and low
manufacturing cost. Our factory has been making rotary dryers for
drying sand since 1950s. Back then only single-pass rotary dryers
were available for all drying processes. As entering 21st century,
all industries facing more and more environmental challenges and
higher demand for energy efficiency. Our factory started to R
&D Triple-pass Rotary Sand Dryers in 2002, which now has
basically replaced conventional single-pass rotary dryer in sand
drying plants.
Rotary dryer is widely used to dry materials in industries like
cement, mine, construction, chemical, food, compound fertilizer,
etc. Thermocouples are installed in feeding and discharging units
to control temperature. Temperature change of the dryer also can be
indicated by the thermometer, which is convenient for temperature
control inside the dryer ( it is usually 250-350℃).

Working Principle :
The material to be dried is pushed back immindiately by spiral
board when enters the shell from feeding tank and feeding chute.
Because the drier is installed in slope, material flows to the back
end under gravity and rotation force, meanwhile, it is lifted by
board repeatedly and thrown down accordingly, which make the
material form even curtain, and exchange heat sufficiently with
inner the heat flow. In the end, water in the material is dried by
repeatedly scattering.
Application:
The equipment is used for drying yellow sand, slag, clay and other raw materials, widely used in building material, chemical industry, casting and glass industries
etc,
Advantages:
(1.) Special thermal design concept, eliminate heat loss, increase wind
tunnel heat transfer area and
unit volume,
(2.) energy saving effect of good evaporation strength
(3.) Accord with international to create an environment friendly,
resource saving social policy, is the
replacement of traditional drying equipment environment friendly
products.
(4.) Fuel can adopt to the hard coal, oil and gas.
(5.) Can drying the clumpy and powder material which size is below
20 to 40 mm.,apply to Food, feed,
chemicals, pharmaceuticals, mining and other industries.
(6.) No air leakage, thoroughly solved the seal difficulty
(7.)Initial material moisture content 15%,it's ensure below 0.5-1%.
It's the first choice of the Ground
slag, the dry mortar plant and other various drying engineering.
