Sand Drying Line

Brief Introduction
Sand rotary drying line 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 mining system. 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 . 


Working principle of sand rotary dryer/drying line
 The material to be dried is pushed back immediately by spiral board when enters the shell from feeding tank and feeding chute. Because the dryer is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering. 


Features of sand rotary dryer/drying line
 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℃ (single cylinder dryer outside shell temperature as high as 150℃), output of low temperature, discharging temperature below 60℃.  
 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.
