The Sand dryer equipment 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.
    Sand dryer equipment 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.
