Brief Introduction of Sand Rotary Dryer:
1. The Sand Rotary Dryer is depending on the practice in sand and
stone production, absorbing the leading technology home and abroad,
and is widely used in sand making industry.
2. The Sand Rotary Dryer is of high efficiency and has the features
of reasonable structure, high capacity and low consumption.
3. The Sand Rotary Dryer can make final products free from dirt and
impurities and reduce the high quality sand loss.
Application of Sand Rotary Dryer:
1. Sand Rotary Dryer is widely used in a variety of materials
drying operations. As reliable operation, convenient operation,
strong adaptability, large capacity, it is widely used in
metallurgy, building materials, food, light industry, chemical
industry, coal, medicine and mining industries.
2. Sand Rotary Dryer is suitable for drying granular materials in
general. It can also be mixed with some materials by drying sticky
paste materials or materials with higher water content. Commonly
used in dry sand, slag, coal, animal waste and so on.
Structure of Sand Rotary Dryer:
The Sand Rotary Dryer consists of the cylinder, before and after
the roller circle, a large gear, gear roll, drag roller, a small
gear, a feeding device, lifting plate, reducer, motor, feeding
device and other components. Furnace can be designed according to
user needs, the combustion chamber, bucket elevator, belt conveyor,
feeder, dust and other system equipments.
Working Principle of Sand Rotary Dryer:
The wet material from the belt conveyor or bucket elevator to the
hopper, and then by feeder feeding through the feeding device into
Drum sand rotary dryer cylinder into a slightly tilted to the
horizontal rotating cylinder.
Adding material from the higher end, low-end entry by the heat
carrier, and the material into a counter-current contact, but also
heat carrier and the material together and flow into the cylinder.
With the rotating cylinder, the material runs by gravity to a more
Wet material in the cylinder body to move forward the process,
directly or indirectly heating the heat carrier, the wet material
to dry, and then the discharge end by the belt conveyor or screw
Tumble dryer wall of the cylinder body with lifting plate, its role
is to copy the material up and planted, so that the surface of the
material increases the contact with the air flow to improve drying
rate and to promote material progress.
Heat-carrier is generally divided into hot air, flue gas.
After heat-carrier around cylinder slag dryer machine back then,
generally require cyclone trap the gas inside the material brought
For further reduction of dust content in exhaust gas should be
handled through the bag filter before discharge.
