Product Description
The three return Dryer is a new energy-saving drying equipment, the whole
European energy-saving technologies - mosaic structure. In the dry mortar
production line is mainly used for drying sand, river sand, river sand, sea
sand, quartz sand, garnet sand, humidity, than the major materials. Wet
material sand feeder continuously and evenly delivered to the inner cylinder,
throw and move forward through the spiral lifting plate, the other from the
middle to break up the device to form a curtain-like heat full contact. Leads
to the rapid formation of water vapor by the induced draft fan. Almost dry
material into the in-tube, the outer tube. Into a silo full contact heat to
meet the drying requirements.
Three-pass dryer are also often used in the slag, limestone, clay, slag
drying production line, mainly by the disc feeder (increase), belt conveyors
(can be lengthened and widened), the body of the dryer, stove , blowers,
grading screening equipment, dust removal system (the Shaq Long or water dust)
and other components. Full drying equipment design, well-made, stable
performance, advanced technology, high yield, less coal, small footprint, less
artificial, low-carbon, etc..
Return Dryer advantages:
1, equipment investment is 20% of the foreign products, the manufacture of
wear-resistant manganese plate, 3-4 times than ordinary steel wear.
2, 15% of the initial moisture of the material, final moisture to ensure
that 0.5-1%, cement plant slag powder, dry mortar production line and other dry
product of choice.
3, improve the thermal efficiency of more than 40% than the traditional
single-cylinder dryer.
4, the fuel can be adapted to anthracite, bituminous coal, coal gangue, oil,
steam, bake 20-40mm block material, pellets, powder materials.
5, covers an area of about 60% less than monocular dryer. The construction
investment reduced by about 60%, easy to install.
6, seamless wind phenomenon, completely solved the sealing difficulties.
7, a material temperature of ≤ 60 degrees, can be directly into the
database, covered-cooled feed is not needed.
8, the outer shell temperature ≤ 60 degrees, the exhaust gas temperature
<120 degrees, dust removal equipment use time more than 2 times.
9, coal consumption is 1/3 of the single-cylinder dryer, saving 40%, tons of
standard coal consumption <9 kg.
