Henan BH Machinery New Technology Three Cylinders Sand Rotary Drum
Dryer
Description:
The three-pass dryer is a high-efficiency combined three-cylinder
dryer. Large three-cylinder dryer, usually 6 to 7 meters long, is
divided into two types of structure: straight tube and cone tube.
The flow of material is carried out by the inner blade of the
cylinder (ie, the deflector). Suitable for straight or cone
construction. The three-pass dryer is nested by three concentric
cylinders of different diameters, rather than interlocking, which
is a chain. This special structure determines the amount of
production, so this new type of drying The dryer is also called the
three-pass dryer. The LJSH high-efficiency combined three-cylinder
dryer has a compact structure and a small footprint. It is one-half
of the same output single-tube drying floor area, reliable in
operation and energy consumption. Low, high thermal efficiency,
good material drying effect, easy to achieve automatic control, and
fewer operators.

Working Principle :
Three cylinders rotary drum dryer main consists of rotary body,
lifting blade, raise material board, transmission device,
supportive device and sealing ring etc. (Optional auxiliary
equipment includes combustion chamber, feeder and discharging
device, and dust collection equipment).
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.
The main purpose:
The high-efficiency combined three-cylinder dryer is mainly used
for drying granular materials in a certain humidity range, such as
yellow sand used in the dry mortar industry and various
specifications of sand used in the foundry industry. Blast furnace
slag for building materials and cement industry. Small-grained
clay, used in the chemical industry for small-grain materials that
do not chemically change, are not afraid of high temperatures and
soot. According to the requirements of different industries for the
final moisture content of the dried materials, the moisture content
of the dried materials can reach 1 to 0.5%.
The material entering the dryer is preferably a non-stick wall and
a lifting plate. The temperature of the gas entering the heat
exchange in the dryer should not be higher than 750 degrees
Celsius. If there is special requirement for high temperature
drying, the inner tube and the poplar plate at the entrance of the
dryer can be made of heat-resistant steel plate.
