Descriptions of Three Return Dryer:
1. Sand dryer is can be also called drum dryer, or dryer drum or
rotary dryer machine, etc.
2. It is a kind of drying equipment widely used in mining system.
3. Applying to dry metal and magnetic , heavy , floating
concentrate , the clay of cement industries and the slime of coal ,
etc . It has an advantage of high efficiency ,easy operation.
Features of Three Cylinder Drying Machine:
1. Compared to single cylinder dryer this small sand dryer length
shortens 60%, in favour of process arrangement. Reduces workshop
covered area, reduced the project investment by 40%. Occupation
area: about 20m2.
2. Adopted latest technology, cylinder self insulation, thermal
efficiency is as high as 80% (single cylinder dryer is only 35
percent), thermal efficiency than single cylinder drying saves coal
68%, yields 100%.
3. Heat-resisting wear-resisting alloy steel plate, four times than
ordinary steel wear-resisting. Long service life and easy
maintenance.
4. High thermal efficiency, outside shell temperature below 60 °C
(single cylinder dryer outside shell temperature as high as 150°C),
output of low temperature, discharging temperature below 60 °C.
5. Output of low temperature, be helpful for dust collector to use
a long time, can be directly supporting air tank pulse bag filter.
6. Construction investment reduces 50%, power consumption reduces
60%.
7. Adopts roller rotation, no need reducer.
8. Hot air stove can supporting fluidezed bed, spray stove, hands
burned furnace, also used in fuel and gas type, can bake the below
20 mm pieces of materials, aggregates, powder material.
9. After drying the moisture content of materials at 1-0.5% and
below, which can meet different industries requirement.
