The three-cylinder dryer also known as the three return dryers are
wet material drying equipment series products, is in rotary drum
dryer based on the improvement of high efficiency and energy saving
products.This dryer improved the internal structure of the original
single tube rotary dryer, increase into the machine before the wet
material of drying and prolong the drying time of the wet material
in the machine, plus seal, moisturizing and reasonable supporting
measures, make the drying machine production capacity compared with
the original single drum dryer, 50-80%, unit volume evaporation
intensity of up to 120-180 kg/m3, the standard coal consumption for
6 to 8 kg/t only.The three-cylinder dryer is widely used in various industries of
iron ore powder, slag, clay, coal, and other composite materials,
construction of dry mortar, yellow sand as well as chemical
industry, foundry industry such as raw material drying.
The three-cylinder dryer works:
The three-cylinder dryer work by feeding device when the material
into the rotary drum of lining, realize the downstream drying,
inner material constantly grabbed, scattered under the copy board
of a spiral rolling to realize heat exchange, move to the other
side of the lining material into the middle, counterflow drying,
material in the middle are constantly repeated Yang into, is
marching into two steps forward and one back, material in the
middle is fully absorb heat coming from the inner cylinder, and
absorb the middle roller heat and prolong the drying time again at
the same time, dry material in the best condition.Material to the middle at the other end and into the outer material
within the outer cylinder rectangular loop travel more, to achieve
the effect of drying in hot air under the action of moving fast
discharge roller, did not achieve drying effect of wet material
because of the weight can't advance rapidly, the material in this
rectangular copy board to fully dry, dry end.
The three-cylinder dryer key features:
1, the equipment investment is needed for 1/6 of the imported
2, material moisture to ensure below 0.5%, dry mortar and slag
powder production line is the preferred product.
More than 3, barrel self insulation thermal efficiency is as high
as 70% (traditional single drum dryer heat efficiency is only 35%),
improve the thermal efficiency is 35%.
4, fuel can be coal, oil and gas.Can bake 20 mm below the piece of material, pellet and powder
5, covers an area of about 50% lower than single drum dryer and
civil investment to reduce 50%, power consumption reduced by 60%.
6, can according to user requirements of regulation to easily.
7, the low temperature, dust removal equipment with long time.
8, no size gear transmission, using the wheel transmission.
The advantage of the three-cylinder dryer:
My company produces three drum dryer has a compact structure,
simple structure, rational layout, increase the rate of material
and heat exchange of heat energy, make the material drying effect
is good;Basic inputs, one half is only part of the same production single
cylinder dryer, reduce the one-time investment;Reliable operation, low energy consumption, high thermal
efficiency;At the same time, easy to realize automation control, reduce the
operating personnel, save labor resources.
Three drum dryer is mainly used for drying humidity and granularity
range granular materials.Such as yellow sand, sand, slag, clay, coal cinder, small size and
not afraid of high temperature smoke dirty and other small particle
materials.Material moisture after drying can reach 1 - less than 0.5%.
