High Thermal Efficiency Intermittent Industrial Drying Equipment For Quartz Sand
 
Equipment Introduction:
 
High thermal efficiency Intermittent industrial drying equipment is improved on the basis of traditional
rotary drum dryer, the feeding, drying and discharging process of the dryer is intermittent, the drying 
time can be set up according to the temperature of drying medium, the moisture of the feeding and 
discharging material and other factors. It is applicable for drying sludge, coal, sand, animal dung, fly 
ash, clay, coal slime, ore, steel slag, quartz sand, kaolin clay, bentonite, sawdust, desulfurization 
gypsum, compound fertilizer and other materials by utilizing of tail gas waste heat. Advanced internal
 structure strengths heat exchange, that is to say, increasing thermal efficiency.
 
Working Principle:
 
The corotation of the cylinder is the feeding stage when the feeder starts to work, and the feeder stops
 once the set feeding quantity is reached. And then the cylinder rollbacks and enters the stage of drying,
 the drying medium will be drew into the cylinder of the dryer by the induced draft fan at the end of the
 drying system, to do the heat exchange with the materials being lifted up constantly inside of the dryer,
 the evaporated moisture is taken out continuously by the hot air, the material to be dried to qualified
 moisture content after a certain period of time. At last, the cylinder corotates once again, the dried
 material is discharged from the dryer cylinder under the push of discharging screw, one time of drying
 process has been finished.
