2.7×7 High Thermal Efficiency Three Cylinder Industrial Drying Equipment
For Yellow Sand
Equipment Introduction:
High thermal efficiency three cylinder industrial drying equipment
improves the internal structure on the
basis of single drum dryer, the pre drying of wet material is added
before getting into the dryer and
prolong the drying time of wet material in the dryer. It is widely
used in various industries’ slag, clay,
coal, iron ore powder, ore powder, and dry mixed mortar, yellow
sand and other mixed materials.
Performance Characteristics:
1. Low outlet air temperature, longer service life of dust removal
equipment.
2. Gear driving is not required and it’s directly driven by roller,
with higher mechanical efficiency.
3. Without the phenomenon of air leakage, the sealing difficulty is
totally solved, and the installation can
be finished within a few hours.
4. 50% of area covers has been reduced compared with the single
drum dryer, and land investment
reduced by 50%, power consumption reduced by 60%.
5. Advanced internal structure strengths heat exchange. The
self-insulation thermal efficiency of three
cylinder dryer can reach above 70% (the self-insulation thermal
efficiency of traditional single drum dryer
is only 35%), it has remarkable energy saving effect.
6. Less than 1% of material moisture can be assured by the
three-cylinder dryer, which is the preferred
product for the dry mixed mortar and slag powder production line.
7. The temperature of discharged material is < 50 ℃, which can
be directly conveyed into the storage
silo, needless to cool down in the cooling shed.
Working Principle:
Materials get into the internal rotary drum from the feeding
device, to realize the downstream drying,
materials are lifted up and down constantly by the inner layer
lifting plates and the heat exchange is
realized under the form of spiral moving, materials move to the
other side of the inner cylinder and then
get into the middle cylinder, and materials are lifted up and moved
forward in the middle cylinder, by the
way of two steps forward and one step back, materials absorb the
heat both coming from the inner
cylinder and the middle cylinder, meanwhile, the drying time is
prolonged, and materials reach optimum
drying status at this stage. Material move the other end of the
middle cylinder and then get into the
outer cylinder, the dried materials are quickly discharged from the
cylinder under the function of hot
wind.
