Product Descriptions:
Three cylinder river sand dryer is also called three drum dryer, or
dryer drum or rotary dryer machine, etc. It is a kind of drying
equipment widely used in mining system to dry metal and magnetic,
floating concentrate, the clay of cement industries and the slime
of coal, etc.
Working Principles:
Material are delivered to the hopper by belt conveyor or bucket
elevator . Then they go into the the charger tip by passing through
the pipe of charger. When materials go into the tip of the dryer ,
heat carrier go into the dryer with material.After that ,they go
into the discharging exit by passing through inner drum , middle
drum and outer drum to go into the discharging storehouse .
After heat carrier pass through the dryer it needs cyclone dust
collectors to gather in the material within the gas . If you want
to reduce the amount of dust within tail gas , you should use bag
duster or wet process duster to discharge .Then, materials are
sifted and segregated qualified production by linear vibrating
screen.

Sand Dryer Classifications:
1. According to the heat transfer between the drying medium and wet
materials, rotary dryer can be divided into direct heat transfer
rotary dryer (the direct contact and heat transfer between drying
medium and wet materials) and indirect heat transfer rotary dryer
(the heat required by the drying process is indirectly passed to
the wet materials by the cylinder wall).
2. Indirect heat transfer rotary dryer is rarely used due to its
low transmission efficiency and complex structure and it can be
divided into single passage rotary dryer and triple passage rotary
dryer according to the quantity of the shell drum.
Features:
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. Small occupation area, low construction investment,convenient
installation.
