Sand Three-Drum Dryer is developed on the basis of traditional single drum dryer, which
is a kind of direct rotary dryer. In drying process of double-drum
dryer, the materials to be dried directly contact with heat
carrier, thus realizing better drying effect and making heat
exchange more full. Meanwhile, double-drum dryer has reduced
manpower allocation, which saves labor resource.
Sand Three-Drum Dryer Application:
Slag, coal, clay, sand, limestone and so on.
Sand Three-Drum Dryer Features:
Sand Three-Drum Dryer is new type of highly efficient drying
equipment developed after many years of improvement of single drum
rotary dryer. Three-drum dryer has three-layer external cylinder,
which can better utilize residual heat. Besides, the three-drum
dryer has increased pre-drying time of wet materials before
entering dryer machine and extended seal and drying time, which can
improve efficiency by 50% to 80%. Sand Three-drum dryer which is of
advanced technology, reasonable operating parameter as well as
simple and feasible operation can be widely applied to drying
operation of slag, clay, coal, mineral powder and other materials
in various industries. Three-drum dryer is highly efficient and
energy-saving, which easily realizes automation control and is the
updated product of traditional dryer machine.
