Three Cyclinder Rotary Sand Dryer Machine For Limestone Drying And
Sand Drying
Three Cylinder Sand Dryer Description:
1.MG series three cylinder sand dryer is produced with three different diameter homocentric cylinder
according to the certain mathematical relationship and cylinder
structure then combinated by embedded with each another.
2.Due to special structure of threecylinder dryer, the length of the
cylinder body is the single cylinder dryer one third. The
occupation area than the single cylinder dryer save 65%, thus the
capital construction investment deduced accordly.
3.MG series thress cylinder sand dryer adopts roller and belt
friction transmission, has a low power transmission and reduces the
noise of equipment. Sealing system adopts a micro touch technology,
has a better sealing effect, reduces the
dust pollution. This dryer use coal, oil, gas and other various
fuels, can dry lump, particle shape,and powder and so on many kinds
of materials, accord with a policy to create an environment
friendly, resource conservation-oriented society, and is an
environmental protection energy-saving products which is the
replacement of traditional drying equipment.
Advantages of sand dryer machine:
1. The cylinder is advanced in technology and can preserve heat by
itself. Its thermal efficiency can reach 80% in thermal
efficiency(35% for single cylinder dryer), 68% in coal saving and
100% production improvement than the single cylinder dryer.
2. The whole length is 60% shorterthan single cylinder dryer, which
creates great convenience to process layout and building area
reduction (the covering area of three-cylinder dryer is about20m2).
40% of the project investment can be saved.
3. The three-cylinder dryer adopts the heat resistant and wear
resistant alloy steel plate which is 4 times stronger than the
common steel plate. So it is longer in service life and easier to
repair.
4. The thermal efficiency is high. The temperature of outer
cylinder is below 60℃ (that of single drumdryer can reach 150℃).
The discharging area and final materials also have a low
temperature—below 60℃.
5. The low temperature of discharging area can prolong its service
life and can be equipped with the pulsed baghose precipitator with
air box directly.
6. It can reduce about 50% building investment and 60% electricity
consumption.
7. It is driven by the riding wheel, needing no big and small
gears.
8. The hot stove can be equippedwith furnace in fluid bed, coal
spraying stove, hand stove, oil stove and gasstove and suitable for
block, granular and powder shaped materials smaller than 20mm.
Materials enter the inner side of the drum through the feeding
device to realize current flow drying process, then the materials
enter the middle layer of the inner wall through the other end to
realize counter current drying process. They are lifted in over and
over in the middle layer which advance in two-steps forward and
one-step back way. The three-drum dryers absorb heat from both
inner drum and middle drum, which extend the drying time and
realize the best drying condition. Finally, materials fall into the
external layer of the drum from the other end of the middle layer,
processing in a rectangle multi-loop way. The dried materials move
quickly out of the drum under the hot air, while the wet ones
remain because of their own weight. Materials are dried completely
inside the rectangle shoveling plate and then cooled by the single
drum cooler, thus finishing the whole drying process.
Application of three pass river sand drum rotary dryer:
Three pass river sand drum rotary dryer is made by our company used
on building materials, metallurgy, chemical industry, cement plant
for drying of sand, sawdust, wood shavings, chicken manure, iron
ore, limestone slag, coal powder, slag, clay stone,etc. This Rotary
Drum Drier is composed of rotary body, lifting blade, driving
device, supporting device and sealing ring,etc.
