Small Triple Pass Cement Industrial Slurry Sludge Silica Sand Clay
Drum Drying Machine Price
Introduction
Three-cylinder rotary dryer is mainly applied for stoving slag,
sand, coal, fly ash, iron powder, ore, quartz sand and other
particle materials. It has the following characteristics:
1. The cylinder protect itself, thermal efficiency can up to
95%.The whole length of the dryer reduced to 50% approximately than
mono-cylinder and reduced land investment to 50% approximately
2. Cylinder adopts heat-resistant and wear-resistant steel plate
welding with long service life and easy maintenance..High thermal
efficiency , temperature of outer cylinder is 60or
below(temperature of outer mono-cylinder is high to 150°C)
3. Low temperature of outlet, long-service of dust removal machine.
It also can be directly connected to air box pulse bag filter.
4. Without gear and pinion drive, but wheel rotation applied, level
operation of the complete machine makes system simple and
reasonable.
5. Air heater could match boiling furnace, or oil furnace can also
be applied, which can dry materials with size below 20mm.
6. Final moisture index can be adjusted according to requirements
of customers.
Application
The Rotary Drier is widely used in the field of building materials,
metallurgies, chemical industry, cement and so on. It can dry slag,
coal powder, mining powder, clay, sand, limestone and so on. It is
made of rotary body, lifting blade, driving device, supporting
device etc. The dryer has advantages of reasonable structure, high
efficiency, low energy consumption and convenient for
transportation.
Working principle
1.The material first goes into the inside drum, because there are
the spiral shape boards fixed in the drum, when the dryer make
rotary working, the spiral shape board will stir the material and
make the material do movement.
2.When the material reaches the right side of the drum, it will go
into the second drum for further drying.
3.The same working principle, the material then goes into outside
drum, during the drying working process, the material will make
three times drying, so the material can be dried completely in this
process.
