What’s the rotary sand dryer machine?
The river sand dryer machine is can be also called drum dryer, or
dryer drum or rotary dryer machine,etc, it is a kind of drying
equipment widely used in sand,yellow sand,slag,clay and other raw
materials,widely used in building materials,chemical
industry,foundry industry,etc,can adapt to a variety of fuels such
as coal,oil and gas. It has an advantage of high efficiency ,easy
operation.
Features and advantages of three return sand dryer:
1 | Unique design more than 20 drying room,which greatly promotes the
contact are of the heat and material,make full use of heat,reduce
energy losses. |
2 | Special support wheel channel design,greatly extend the life of
support wheel,widened and thickned the roller run,no worries,when
the dryer is mould,then to locate the machine,ensure the machine
can’t run away. |
3 | Guide vane is adopted special alloy steel material which is
wear-resistant high temperature resistant. |
4 | The dischanrging temperature is low,can be directly into the
storage soil,unnecessary cooling.The fuel can be
anthracite,bituminous coal,oil,steam,low consumption. |
5 | Smalloccupation area,low construction investment,convenient
installation. |
Working Principle of sand drying machine:
1. The heat source of rotary river sand dryer comes from the
combustion train, and adopts down-flow heating methods.
2. When the materials enter into the body from feeding device, it
will be pushed back by the spire raising board.
3. As the dryer is in an inclined position, the materials will be
down to the lower end under the influence of gravity and rotation,
but the raising board will be threw to the upper end for
scattering.
4. This process make the material well-distributed in the body,
then ensure the heat exchanged by heat wind.
5. After repeated cycle with this process, the moisture content can
be dried.
Applications of Three Cylinder Dryer Machine:
| Applications | Powder & Particle: Sands, limestone, stones, clay, mineral filter
cake, coal, iron sulphate, filter cakes, fly ash, gypsum etc. |
|
| Damp and sticky material: Coal slime, sewage sludge, bentonite,
Kaolin etc. |
|
| Corrosive material: Distillers' grains, Fertilizer, animal dung,
slag etc. |
|
| Biomass material: Sawdust, wood chips etc. |
